The Russian Federation has a great number of land plots to be used for a particular purpose, which depends on the category and type of the land. Agricultural land plots are of particular importance for the regional economy because they are subject to the local tax, established by the municipalities, i.e., land tax makes up a significant share of local budget revenues. Prompt and correct accounting of agricultural land improves the local budget. The authors determined the area of agricultural land in the Kemerovo Region and calculated the budget effect from their use. They also identified the potential income to the regional budget. The appropriate land measurement and classification proved to have a positive impact on the budget of the Kemerovo Region. The article contains an assessment of potential tax fees to the budget of the Kemerovo Region, as well as the amount of fines for irrational or improper use of agricultural lands.

Introduction. The review of existing ideas of artificial intelligence implementation in the construction industry is carried out. On the basis of the studied data the applicability of the technologies was analyzed and their economic efficiency was evaluated, as well as the feasibility of investment in potential projects was substantiated.

Forests are both an irreplaceable natural resource and a vital economic asset for all humankind. Based on the data of counties in mainland China from 2007 to 2020, the article explores the direct impact and spatial spillover effects of the policy implementation on the economic growth of counties with the help of the forest city pilot policy and the policy evaluation model. The results reveal that policy implementation can have a positive economic growth effect on the pilot counties, which, in turn, can significantly increase the size of the county's GDP, the level of GDP per capita, and the total amount of nighttime lighting brightness. The implementation of forest city construction can bring about 2.74% of total GDP size, about 2.63% of per capita GDP development level, and about 7.25% of nighttime light brightness to the county on average. Cost–benefit analysis also indicates that forest city construction can bring about a comprehensive economic benefit of approximately CNY 686.453 million (approximately USD 96.82 million) to the counties. The rapid improvement in labor productivity, significant influx of high-end factors, and continuous expansion of market potential are important mechanisms through which policy implementation promotes economic growth in pilot counties. While promoting economic growth in the pilot counties, forest city construction can also have positive spatial spillover effects on neighboring areas in the pilot counties. Furthermore, when the deficits in atmospheric vapor pressure and annual evapotranspiration are used as instrumental variables for forest city construction, the empirical estimates are not significantly altered. In the process of building forest cities, county governments should be wary of issues such as the high cost of forest maintenance. This study provides a Chinese model and policy reference for other countries and regions in the world to deal with the relationship between forest city construction and county economic growth.

Introduction: The potato holds the distinction of being the world's largest non-cereal food crop and ensuring its sustainable production is imperative for global food security. Notably, China leads in both the planting area and output of potatoes globally, cementing its crucial role in the nation's agricultural economy. A scientific assessment of the effectiveness of organic fertilizers on potato cultivation can significantly contribute to the promotion of sustainable agriculture. Methods: This study utilizes a Propensity Score Matching (PSM) model and introduces a novel cost-efficiency approach to analyze and evaluate the production efficiency and economic impact of organic fertilizer application among 546 potato growers in Shandong. Results: The research findings reveal the following: Firstly, compared to the control group without organic fertilizer application, it is evident that the use of organic fertilizers enhances production technology efficiency, labor productivity, land productivity, and net profit per unit by 3.6%, 1588.47 kg/ person, 16346.77 kg/ha, and 16135.32 yuan/ha, respectively. Secondly, an examination of cost efficiency among growers with different production scales indicates that those with a planting scale of 0.667-1.333 hectares demonstrate relatively high production efficiency across multiple factors. Additionally, there is an observable inverted U-shaped trend in the relationship between planting scale and production efficiency. Thirdly, the continuous application of organic fertilizers proves advantageous in mitigating inefficiencies in investment techniques, leading to cost savings and efficiency improvements in potato cultivation. Discussion: Consequently, it is recommended that the government and relevant departments enhance technical support, elevate professional training programs, and optimize the allocation of input factors. These measures aim to encourage farmers to adopt organic fertilizers, thereby promoting sustainable agricultural practices. [ABSTRACT FROM AUTHOR]

• Coal, sawdust and their mixtures were combusted in the fluidized bed of catalyst. • Addition of biomass increase the burnout degree up to 99.9% at 750 °С. • Addition of biomass decrease the environmental impact of combustion. • Combustion at 750 °C with the highest amount of sawdust is the most profitable. • Presence of CaO and MgO prevents SOx emission and slagging of heat exchange surfaces. The work is devoted to the study of combustion of brown coal, pine sawdust, and their mixtures in a fluidized bed of catalyst at 600–750°С. It is shown that an increase in the content of sawdust in a mixture with brown coal leads to an increase in the burnout degree of solid fuel from 94.4% to 99.9%, while the emission of greenhouse gases in the form of CO 2 CO and NO x is reduced (CO 2 from the biomass is not included in the balance). The high content of alkaline earth metal oxides (CaO and MgO) in the mineral part of brown coal, sawdust, and their mixtures eliminates the emission of sulfur oxides and the slagging of heat-exchange surfaces during the combustion in a fluidized bed of catalyst. The optimal temperature, when the highest burnout degree of the above fuels is achieved in the combustion is 750°С. It is also shown that the increase in temperature and the content of sawdust in the composition of the fuel mixtures has a positive effect on the economic and environmental process indicators.

The aim of the study is to evaluate the economic effect of foliar treatment with biostimulants: chitosan, vermicompost and vermicompost + nature-identical growth regulator on organic production of spring rape on organic production of spring rape. Two-years field trials were conducted using a block method with foliar treatment in 2 phenological phases (in rosette and flowering phase). The biological response of the culture at different doses of the biostimulators was investigated. The obtained primary results were used as input data for the construction of an economic-mathematical model for economic evaluation The treatment of spring rape with biostimulators has a positive effect on the yield of the crop. After that, a specific agricultural holding in the region is selected, which will serve as a model on which to construct the optimization model for evaluating the economic efficiency. In this farm, along with the intended crops in the production structure, spring canola is added - controls and treated with BS. The results are optimal after using chitosan in a dose of 500 mL daa-1 . The results of this research show the economic benefits of using biostimulants, which are extremely important for farmers. They are an alternative to the requirements of the European Union's Green Deal At the heart of the Green Deal is the Farm to Fork (F2F) and the ‘Biodiversity Strategy’ (BS) strategy, which was launched by the European Commission in May 2020 to achieve a fair, healthy and sustainable food system by 2030. Under the F2F strategy, there is a need to reduce reliance on pesticides and antimicrobials, reducing excess fertilization, increasing areas for organic farming, improving animal welfare and reducing biodiversity loss. With the announcement of the goals and intentions of the Green Deal and its manifestations in agriculture, preparations also began for preliminary assessments of the consequences and impact that it will have on the entire food chain and for its transposition into the Common Agricultural Policy. At the same time, science research on alternatives to traditional conventional technologies is increasing. The results of the studies also took into account a set of assumptions for simulations of farm incomes, production and product prices. [ABSTRACT FROM AUTHOR]

The growing demand for electricity, driven by factors such as the shift to carbon neutrality and economic growth, is a challenge shared by South Korea and Japan. South Korea, a peninsula nation, and Japan, an island country, which are both heavily dependent on foreign energy sources and have manufacturing-based industrial structures, are actively working to secure stable power supplies for their economic development. This article carries out a quantitative analysis of the roles of the South Korean and Japanese electric power sectors (EPSs) in their respective economies, seeking to identify differences and generate actionable insights for decision making and policy formulation. Utilizing the input–output (IO) technique with the latest available data, the analysis includes a demand-side model, a supply-side model, and a price-side model to examine various effects of the EPSs. The key findings reveal differences in the production-inducing, value-added creation, and job-creation effects between the two countries, highlighting operational disparities in their electricity sectors. Additionally, South Korea exhibits higher wage-inducing, supply shortage, and price-side effects than Japan, because of its public enterprise-oriented high-wage structure and a substantial manufacturing sector. These quantitative results provide valuable reference material for future government decisions and policy development in the EPS and emphasize the significant role and impact of the power sector in both countries.

In this paper, we propose technological principles for determining rational parameters of the supply chain in order to establish a balance between demand and supply for goods in the chain links under conditions of variable demand and optimisation of total costs for all cargo delivery participants, which will affect the final cost of goods to customers. For the experimental research of the supply chain functioning, the forecast values of demand were determined based on the study of demand trends. As a result of the research conducted using mathematical modelling, regularities of the influence of supply chain parameters on the total costs of delivery participants have been established and rational parameters of the supply chain for consumer goods customers in international connections have been determined, minimising additional costs and ensuring a minimum level of total costs. The positive results of the economic effect estimate demonstrate the effectiveness of the proposed solutions.

Production digitalisation is a significant factor in the development of mechanical engineering that triggers countries and regions’ economic growth. Implementing digital integration at industrial enterprises implies that production operations are linked through a corporate information system. The paper aims to develop and test a method for assessing the economic effect from digital integration at mechanical engineering enterprises. Methodologically, the study rests on the theories of production organisation and integration as well as the main postulates of the concept of industrial digitalisation. The study applies methods of econometric modelling. The evidence base is the information about the activities of one of the Ural macroregion’s largest mechanical engineering enterprise – Production Association “Ural Optical and Mechanical Plant named after E. S. Yalamov” (UOMZ). The paper systemitises ideas about the essence of the economic effect from digital integration. The case of the enterprise is used to identify the level of specific costs in this process and to forecast their changes depending on different factors using econometric modelling. The value of the findings consists in broadening the scientific and practical understanding of the economic effects brought about by industrial digitalisation.

In modern heavy-loaded friction units, various types of antifriction coatings are used on the surface of the bearing profile of the bearing sleeve to ensure high load-bearing capacity and increase the duration of the hydrodynamic regime, and consequently, the economic effect of sliding bearings. In the study, the creation and development of mathematical models of a radial sliding bearing with an antifriction polymer coating of the support surface containing a groove is carried out. The key role here is played by the method of analytical forecasting, which determines the mechanism of friction and the conditions for its transition from boundary to liquid. The aim of the study is to develop a mathematical model of a radial sliding bearing with a polymer coating of the bearing sleeve bearing surface containing an axial groove to predict the economic effect. The objective of the study is to develop new mathematical models and analyze the movement of lubricant in the working gap of a radial sliding bearing, taking into account design features to predict the economic effect. The difference from the existing models of tribosystems with antifriction coatings is the presence of a groove, which ensures stable ascent of the shaft on the hydrodynamic wedge and reduces wear during start-up and run-outs, hence increasing the service life of tribosystems. Using the lubricant motion equation and the continuity equation, new mathematical models are obtained that take into account the design features of the bearing sleeve surface – polymer coating, groove width, rheological properties of the lubricant used. Based on the results of an experimental study on the AI 5018 friction machine, the economic efficiency of net discounted income was calculated on samples in the form of partial inserts. As a result of the research, new mathematical models for engineering calculations have been developed that allow predicting the efficiency, reliability and duration of the hydrodynamic lubrication regime, as well as determining the main tribotechnical parameters. Net discounted income based on the results of theoretical and experimental research is estimated at 0.36 million rubles per year.

The article discusses the concept of efficiency in the context of assessment system solutions and the methods used to measure it. Efficiency is defined as the ability to produce effects and achieve results, while effectiveness is understood as the outcome of certain actions. Efficiency theory is based on operations research and decision-making methods using mathematical models such as probability theory and machine learning techniques. The results of performance measurements can be used to solve a variety of practical problems related to unmanned aerial vehicles, including comparing similar systems, conducting operational assessments, and optimizing requirements. The paper also discusses the modification of flight control and planning models, where stochastic parameters that affect mission quality need to be considered. Societal effects, such as flight normality and safety, can be measured by direct assessment methods and statistical metrics. More generalized metrics can be used to assess flight safety by comparing the number of accidents and workload. Suggested methods include the use of mathematical models and integration techniques to assess flight safety. [ABSTRACT FROM AUTHOR]

The winter and spring varieties of peas (Pisum sativum) require careful study of the entire range of technological measures, including seeding rates, as the basis for optimal sowing density and the formation of phytocenose crops. This issue has not been resolved to date, not only in the context of agrobiological justification but also in everyday practice in Ukraine. This research was carried out in a field experiment in a three-way factorial experiment: factor “A” was the type of development – winter and spring; factor “B” was the variety – spring peas (Svit and Darunok Stepu) and winter peas (Moroz, Enduro and Baltrapp); and factor “C” was the seeding rate. According to the field studies, differences in the physiological and biochemical parameters of the P. sativum test culture characterised the photosynthetic activity of the plants, considering the type of development and variety. The winter varieties of P. sativum were characterised by a higher chlorophyll content (by 35–40%) compared to the spring varieties, which had an economic effect with an increase in the yield of dry biomass of the experimental crop and a decrease in seeding rates, with the formation and increase in grain yield by 14–18%. The intensity of chlorophyll in the process was not a determining factor in the accumulation of organic biomass. The extensive nature of the integration complex was noted (the amount of chlorophyll – the amount of biomass). At the optimal seeding rate, a certain specificity was observed in different types of P. sativum: for spring varieties, the sufficient rate was 0.9 million seeds/ha, and for winter varieties, it was 0.7 million seeds/ha. For varieties with a low productivity level (spring – Svit and winter – Moroz), the optimum sowing rate was around 0.7 million seeds/ha. The increase in the seeding rate was accompanied by a decrease in the content of various chlorophyll fractions from 10–12% to 20–26%.

The livestock sector plays a crucial role in sustaining the livelihoods of millions of families across the world, especially in developing countries. However, farming households that rely on agriculture and livestock are particularly susceptible to the impacts of various infectious diseases and natural disasters. This study focuses on estimating the economic burden imposed on households by lumpy skin disease (LSD) in Pakistan and explores the effect of various socioeconomic factors on mortality ratio. Data were collected through a questionnaire survey from 406 farmers and were analyzed through descriptive statistics to calculate the monetary losses. In addition, the study employed fractional probit regression to identify factors affecting mortality ratio. The results demonstrate significant economic impacts of LSD on farm households in Pakistan, leading to direct and indirect losses and reduced milk productivity. Exotic cows were found to be more susceptible to mortality compared to indigenous cows. The study also found that farmers’ education, experience, household income per month, vaccination, domestic-commercial, commercial animals, and access to information were negatively associated with mortality. The findings of this study emphasize the need for preventative measures such as affordable vaccines, treatment, and improved livestock health and welfare to mitigate the negative effects of LSD on farmers’ income and the local economy.

The economic effects of tourism industry during periods of crisis, such as the COVID-19 pandemic, have received significant attention in recent years. The future is likely to pose a range of new challenges and opportunities to sustainable tourism. This paper employs the Markov-switching vector autoregressions (MSVAR) model to investigate the sustainability of tourism's economic effects in Hong Kong, both during periods of crisis and in the absence of crises. The empirical results show that: (1) The MSVAR model is effective in capturing the nonlinear relationship between the economy and tourism and allows for the categorizing of this relationship into four regimes, for example, the "major event crises" regime and the "economic crises" regime; (2) The economic effects of tourism differ noticeably across the four different regimes, and sustainability varies depending on the presence and type of crisis; (3) The Hong Kong economy, and the tourism industry in particular, exhibits high levels of stability and sustainability. In short, economic growth in Hong Kong's tourism industry is capable of rapid recovery following major crisis events, and it has the capacity to rebound quickly into new periods of rapid growth.

The relevance of the subject matter is conditioned by the existing difficulties of operating the wastewater treatment system of large modern cities and the need to make qualitative changes in the structure of their functioning. The main purpose of the study is to investigate the economic effect of restructuring the municipal wastewater treatment system in the city of San Francisco in the context of analysing the promising possibilities of applying this experience in Ukrainian realities. The basis of the methodological approach is a combination of methods of systematic analysis of the experience gained in San Francisco during the restructuring of the wastewater treatment system, with an analytical investigation of the factors influencing the assessment of the economic effect of the implementation of this event. The study revealed the need for comprehensive investment into the restructuring of the wastewater treatment system existing in a large modern city to obtain a sustainable economic effect from the implementation of such programmes and improve the quality of water use services provided to residents of modern Ukrainian cities. The results obtained and the conclusions formulated on their basis are of significant practical importance from the standpoint of prospects for improving the functioning of wastewater treatment facilities in large modern Ukrainian cities and stabilising the overall environmental situation in these cities, as well as obtaining a tangible economic effect from the modernisation of wastewater treatment systems to improve the quality of services provided to city residents

The purpose of the article is to substantiate the feasibility of an integrated approach to the implementation of measures for the restoration and modernization of housing stock and heat supply objects. On the conditional example of heat supply of a heated quarter (which means a small number of residential buildings to be heated, a local boiler room and local distribution heat networks), various modernization options are considered: separate thermal modernization of buildings, modernization of heating networks, modernization of the boiler room, and options for simultaneous modernization of all elements of the chain: production-supply-consumption of heat energy (complex modernization of the heated district). It is proved that precisely a comprehensive modernization, which involves a simultaneous production, coordinated in terms of time and volumes, supply and consumption of heat, is an effective instrument for improving efficiency in the sphere of heat supply and heat consumption. The complexity of modernization in this example involves thermal modernization of buildings in the heated district (with a decrease in heat consumption by 40%) with the simultaneous modernization of heat transmission networks (with a decrease in heat loss when supplied from 20% to 5%) and modernization of the boiler room (with an increase in the efficiency quotient of boiler equipment from 88% to 93%). The implementation of such a project is economically feasible for all participants: consumers reduce the cost of paying for heat supply services by 49%, and the supplier and producer of heat with a slight (up to 6%) increase in heating tariffs provide break-even activities and receive a larger investment resource in the form of a larger amount of depreciation. At the national level, the proposed mass complex modernization of heated districts can almost halve the consumption of natural gas by municipal heat and power engineering and to the same extent reduce emissions of harmful substances into the atmosphere. In addition, it becomes possible to significantly reduce the amount of subsidies from the budget for the payment of housing and communal services by the population.

In modern conditions, cost minimisation for business entities is the main condition for existence in the market. One of the tools for such minimisation is outsourcing accounting. In addition to minimising costs, accounting outsourcing ensures the correctness of accounting, provides high-level advice, and protects against possible fines. The purpose of the study was to investigate accounting outsourcing as a tool for optimising the activities of entities in modern business conditions. The study applied methods of induction and deduction, cause-and-effect communication, tabular and graphic methods, description and concretisation, and logical generalisation. A single definition of the concept of accounting outsourcing was developed, which revealed the characteristic features of outsourcing. The SWOT analysis of accounting outsourcing services demonstrated accounting outsourcing as an effective tool for minimising costs. It is determined that all shortcomings and threats can be eliminated with careful selection of an outsourcer and signing a contract. The stages of accounting for accounting outsourcing consist in developing a document flow schedule that would ensure timely receipt of information for the customer and quality control of the services provided. A unified methodology for determining the economic effect of accounting outsourcing is proposed, which considers the disadvantages and advantages of existing methods, which would allow revealing the economic, organisational, and managerial aspects of outsourcing accounting. The main proposals received by the author based on the findings of the study can be used in accounting based on outsourcing. Further study of the problems of outsourcing as a tool for optimising the activities of enterprises in Ukraine should be directed to the development of laws and regulations to encourage companies to make managerial decisions regarding the use of accounting outsourcing

The article examines the problems of knowledge capitalization in the innovation economy paradigm. The modern globalized world is characterized by the commercialization of educational and scientific activities, the formation of educational ecosystems, as well as the capitalization of knowledge as a resource. The paper describes the theoretical basis of knowledge capitalization and defines the stages of the formation of academic capitalism. It is defined that the capitalization of knowledge is an increase, the maximization of the value of own and engaged intellectual assets, as a result of the increase in the influence of higher education institutions and scientific institutions on the scientific-technical and socio-economic development of society, and commercialization is the process of turning knowledge into a commodity. A system of statistical indicators of capitalization of knowledge within the economy has been established (expenditures on education; the number of patents; share of costs for scientific research and development; costs for innovative activities; share of innovative enterprises in the total number of enterprises; share of income from the sale of innovative products to the total volume of products sold ). The methodology for calculating the model of the change in GDP per capita has been developed, taking into account the indicators of knowledge capitalization, and the algorithm of necessary actions regarding its application has been described. The hypothesis about the impact of capitalization of knowledge on the economic development of the state, namely the change in macroeconomic indicators, such as GDP (gross domestic product) per capita, has been confirmed. The author’s formula for determining the coefficient of the economic effect from the capitalization of knowledge is proposed, which reflects the ratio of investments in knowledge-creating (innovative activity) to the income received from the implementation of an innovative product. Investments in knowledge-creating activities are the number of expenses for scientific research and development, so the innovative product is a patent, as a formalized unit of knowledge. The calculation of the coefficient of the economic effect of knowledge capitalization for Ukraine and the Republic of Poland was carried out, which clearly showed the expediency of implementing the knowledge capitalization experience of Poland and the need for a balanced internal policy to stimulate educational, scientific and innovative activities with the attraction of appropriate investments in Ukraine.

Voucher markets where governments subsidise the consumers of public services to give them a free choice of service provider are implemented by public authorities as a means to reap the supposed benefits of competition and choice. Such voucher markets imply economic costs for the public authority in the form of transaction costs, e.g., for preparation of quality standards and information material as well as approval, coordination and supervision of providers. However, voucher markets may also affect the public authority's production costs through a competitive pressure for increased efficiency and/or by affecting the potential economies of scale for public service delivery. This article shows that in a voucher market without price competition voucher markets increase the public production costs of delivering home help services. Specifically, the larger the share of elderly persons who choose a private provider, the higher the public costs of delivering practical home help. [ABSTRACT FROM AUTHOR]

Drawing on the essence of Marxist consumer economy theory, this paper argues that the innovations of digital technology can effectively facilitate the integration of economies of scale, economies of scope, and long-tail economies. Through careful analysis of the practical case of Xiaomi's business ecosystem, this paper highlights the notion that data serve as both a key production factor and a critical consumption carrier within the context of digital consumption. We thoroughly investigated the influence of the digital economy on transforming consumption behavior among residents by analyzing a range of typical business cases and the latest data that triggered this transformation. Based on the analysis, this paper argues that such transformation can lead to the platform agglomeration effect, the inclusive diffusion effect, and the push-pull effect by highlighting the specific ways in which the digital economy disrupts the consumption-production model and contributes to the upgrading and transformation of traditional industries. Additionally, this paper demonstrates how the digital economy can expand and promote emerging business forms, providing insights into the ways in which digital innovation is reshaping the contemporary economic landscape. This study intends to provide several policy suggestions that can expand domestic demand, promote consumption, drive the high-quality and integrated development of China's digital and real economy, and position China as a strong cyber and consumer nation by using digitalized consumption as a starting point.

With high carbon emission, the low-carbon transition of power sector will be critical for China to achieve the carbon peaking and carbon neutrality goals. The power transition will have an impact on the economy and employment through the value chain. Quantifying the impact is important for China's future energy and welfare policies. This study adopts input‒output model to analyze the impact on economy and employment based on accelerated and slow power transition scenarios. The results show that the low-carbon power transition will have a negative impact on coal power and coal mining and washing sectors, while a positive impact on machine manufacturing and equipment sector. Low-carbon power transition will have a positive economic and employment effect to promote inclusive growth. By 2060, economic output will increase by about 8.50 trillion CNY, value-added by about 3.39 trillion CNY, and employment will increase by about 3.74 million. Although slower coal power transition can stabilize the economic and employment effect in the short and medium run, accelerating the power transition will produce more positive effect and lower job losses by coal power in the long run. By 2060, accelerating transition will boost output by 8.21%, value-added by 8.20% and jobs by 7.97%. Accordingly, the government should establish an all-round just low-carbon transition mechanism.

Introducing the results of innovative activity into economic circulation is one of the essential characteristics of an effective industrial enterprise. Commercializing intellectual property objects involves coordinated production and commercial activity, adopting and implementing scientifically based decisions. This is necessary to successfully pass an intellectual product through all stages of its life cycle.The purpose of this study is to form market processes for commercializing intellectual property objects at industrial enterprises, finding the most effective option for their introduction into economic circulation.The theoretical investigation of the problem made it possible to identify and analyze various possible conceptual approaches to commercializing intellectual property in an industrial enterprise. Among them are market push, market pull, engineering, and reengineering commercialization models.Separate stages of forming the market model for commercializing intellectual property in an industrial enterprise are highlighted. First, the methodological principles of the vertical, horizontal, and vertical-horizontal market processes of intellectual property commercialization have been developed. The peculiarities of an intellectual product’s life cycle are determined; based on this, a market model of intellectual property’s life cycle (model of successive changes) is proposed. Finally, for each of the proposed market processes, the main advantages and disadvantages of their practical use are determined, as well as the areas of their most effective usage.

The trade-off between environment and economy has been one of the hot topics discussed in academia, but there are many disputes among them. Based on the micro data of Chinese listed companies from 2016 to 2020, this paper uses the shock of the Environmental Protection Tax Law (EPTL) in 2018 as a quasi-natural experiment. Our Differences-in-Differences (DID) method is used to study the impact of the environmental governance pressure caused by the EPTL on firms’ total factor productivity (TFP). The conclusions suggest that: 1) The EPTL has significantly improved heavily polluting enterprises’ TFP, and this finding remains stable after a range of robustness checks. 2) The subgroup analysis shows that. The smaller the size of the administrative expenses paid by the enterprises, the larger the effect of the EPTL on firms’ TFP; the positive effect of the EPTL on the TFP of heavily polluting enterprises is not pronounced in the sample of small-scale enterprises; when the degree of financial slack is small, the effect of the EPTL on firms’ TFP is greater; the effect of the EPTL is greater when the enterprises are located in provincial capital and municipalities. 3) Meanwhile, we also find that promoting firm value and stimulating green innovation may be the potential mechanisms of the EPTL affecting firms’ TFP. This paper provides experience summary for the firms’ high-quality development under the background of government environmental governance.

The winter and spring varieties of peas (Pisum sativum) require careful study of the entire range of technological measures, including seeding rates, as the basis for optimal sowing density and the formation of phytocenose crops. This issue has not been resolved to date, not only in the context of agrobiological justification but also in everyday practice in Ukraine. This research was carried out in a field experiment in a three-way factorial experiment: factor "A" was the type of development - winter and spring; factor "B" was the variety - spring peas (Svit and Darunok Stepu) and winter peas (Moroz, Enduro and Baltrapp); and factor "C" was the seeding rate. According to the field studies, differences in the physiological and biochemical parameters of the P. sativum test culture characterised the photosynthetic activity of the plants, considering the type of development and variety. The winter varieties of P. sativum were characterised by a higher chlorophyll content (by 35-40%) compared to the spring varieties, which had an economic effect with an increase in the yield of dry biomass of the experimental crop and a decrease in seeding rates, with the formation and increase in grain yield by 14-18%. The intensity of chlorophyll in the process was not a determining factor in the accumulation of organic biomass. The extensive nature of the integration complex was noted (the amount of chlorophyll - the amount of biomass). At the optimal seeding rate, a certain specificity was observed in different types of P. sativum: for spring varieties, the sufficient rate was 0.9 million seeds/ha, and for winter varieties, it was 0.7 million seeds/ha. For varieties with a low productivity level (spring - Svit and winter - Moroz), the optimum sowing rate was around 0.7 million seeds/ha. The increase in the seeding rate was accompanied by a decrease in the content of various chlorophyll fractions from 10-12% to 20-26%. [ABSTRACT FROM AUTHOR]

Global warming and the urban heat island (UHI) phenomenon have significant impacts on human activities, against which it is necessary to develop effective coping strategies. Based on the local climate zone (LCZ) system, this study used the land-cover and surface temperature data on the Chang–Zhu–Tan (CZT) urban agglomeration in China in 2006, 2010, 2016, and 2020 to analyze the impact of climate change on the land surface temperature (LST) under different land-cover types. The results illustrate that the LCZ map generated on the basis of the improved World Urban Database and Access Portal Tools (WUDAPT) is more accurate and efficient than the traditional method. The accuracy is increased by more than 15%. From 2006 to 2020, the main built-up types in the CZT urban agglomeration were the sparsely built, the large low-rise, and the compact mid-rise types. The low-plant type represents the most significant proportion of the natural types, followed by the water and the dense-tree types. The built-up types in the CZT urban agglomeration tend to be the high-rise, dense, and industrial types. Urban construction land is taken mainly from the sparsely built type of land. The average LST of the large low-rise and heavy-industry zones is significantly higher than the average LST of the three cities. The average LST values for the water and dense-tree zones are significantly lower than the other average LST values. The LST is stable in each LCZ, showing little correlation with the size of the LCZ area. Compact low-rise land use is ineffective against climate warming and inhibits economic growth. Compact high-rise and open high-rise land can not only effectively deal with climate warming but can also significantly stimulate economic growth. This paper helps us to understand the effect of land cover on climate warming and the economic benefits of LCZs in the CZT urban agglomeration and provides strategies to optimize the use of land resources.

Featured Application: This work assesses and compares the respective economic effects of the same amount of production or investment in the natural gas supply sector in South Korea and Japan. This study examines the role of the natural gas supply sector in the national economy by applying input–output analysis to South Korea and Japan. Specifically, the production-inducing effect, value-added creation effect, wage-inducing effect, employment-inducing effect, supply shortage effect, and price-inducing effect were analyzed using an input–output table of South Korea and Japan. As a result, the production-inducing effect, value-added creation effect, and employment-inducing effect of same investment amount in the natural gas supply sector were greater in Japan than in South Korea. On the other hand, the wage-inducing effect of an investment of USD 1 in the natural gas supply sector was found to be greater in South Korea than in Japan. In addition, the supply shortage effect and price-inducing effect in the natural gas supply sector were greater in South Korea than in Japan. The causes of differences in analysis results for each country and their implications were discussed. The results of this study could be a useful reference for the government to establish policies related to natural gas supply in the future. [ABSTRACT FROM AUTHOR]

THE PURPOSE. Development of a methodology for conducting a feasibility study when using a soft start system based on a current inverter for high-voltage electric motors of pumping units of irrigation pumping stations of the first lift.METHODS. Research and calculations were carried out in accordance with the algorithm for compiling the energy balance of pumping units, as well as using the analysis of statistical data.RESULTS. A feasibility study is presented for the feasibility of introducing soft start systems for irrigation pumping stations of the first lift, where, as a rule, powerful synchronous electric motors are installed. A method for determining the economic efficiency of systems or soft starters for electric drives of pumping stations is proposed. The rational use of an alternative soft starter based on a current inverter is substantiated.CONCLUSION. Determining the economic efficiency of introducing soft starters remains a difficult task, since the operating conditions of facilities require taking into account various influencing factors that are not always amenable to accurate assessment. This is the problem of developing a universal methodology for assessing the economic efficiency of introducing soft starters. The proposed methodology for determining the economic efficiency of such systems, based on known methods, complements and simplifies the process of calculations and computational algorithms.

Voluntary carbon market has become a key mechanism of stimulating carbon emission mitigation actions globally. In this study, we calculate the emission reduction potential of Carbon Generalized System of Preferences (CGSP), a dominated voluntary carbon trading mechanism in China, including on-going projects of forestry carbon sinks, waste clothes reuse, installation of distributed photovoltaic power generation system, and usage of energy-conserving devices, as well as other extended methods for their future mitigation potentials. We employ a computable general equilibrium model to delve into the effects of CGSP mechanism on carbon price, economic growth and household consumption, assessing its impact on the equitability of social welfares between urban and rural residents during 2021–2060. Our results indicate that employing the current methods for CGSP would lead to around 5.0 Mt CO 2 reduction annually. since 2018, whereas adopting the extended methods would yield reductions of 157.1 Mt. Promoting forestry carbon sinks and energy-conserving appliances offers the most prominent emission reduction, while low-carbon travel shows the biggest potential going forward. CGSP will loosen carbon constraints on industries in the market and result in a lower carbon price, reducing the economic cost of carbon trading without compromising China's carbon peaking and carbon neutrality goals. Supplementing CGSP could reduce the GDP loss by up to 0.2 trillion Yuan by 2030 and 0.9 trillion Yuan by 2060, compared to the sole operation of compliance carbon trading market. Provided fiscal stimulus policies, CGSP will further reduce GDP loss by 1.1 trillion Yuan in 2060. Different fiscal stimulus scenarios have a strong implication on welfares of urban and rural residents, wherein monetary equivalent incentive will reduce urban-rural income gap by up to 718 Yuan/capita in 2060. [Display omitted] • China's voluntary carbon trading (CGSP) brings 157.1 Mt. carbon reduction per year • Supplementing CGSP into carbon market reduces GDP losses and mitigates costs of industries • CGSP of forestry carbon sinks and energy-conserving appliances offers the biggest emission reduction so far. • Implementing fiscal stimulus policies boosts residents' income and narrow the urban-rural gap.

Fuel tax levy is an appropriate measure to reduce motor vehicle pollution since the government can't directly tax drifting source of pollution. However, this action will affect every part of residents' life, we should take many factors into consideration. This paper is devoted to the environmental and economic effects of various fuel taxes for different departments based on Beijing economy-energy-environment computable general equilibrium (3E-CGE) model. Researches show that raising fuel tax rates for production & import and consumption contributes to air pollution and emission reduction. However, tax increase may hinder economic growth. Higher tax on production & import will lead to stagflation while on consumption will lead to depression. Besides, the influences on different industries also vary. My conclusion is that government should levy fuel taxes as well as pay subsidies to optimize industrial structure and decrease the impact on economy. [ABSTRACT FROM AUTHOR]

High-speed rail (HSR) is an important form of transportation that affects the economic development of the regional spatial structure. However, there is less discussion about the impact of economically underdeveloped regions and the rapid construction of HSR on the region. This study uses a spatial econometric model to explore whether a rapidly formed high-speed rail network with changes in the network structure can bring economic effects based on the spatio-temporal panel data on high-speed rail construction and economic development in western China from 2015 to 2020. First, data of the daily departures between high-speed rail cities were used to analyze the western high-speed rail network's spatial and temporal evolution characteristics. Second, we analyzed the changes in the centrality, external and internal connectivity, and transfer potential of the economic gap of the western HSR network. Finally, we analyzed the different economic effects of the HSR network structure by combining the Cobb–Douglas production function with the spatial econometric model. The conclusions are as follows: (1) The HSR network in western China is dense at the intra-provincial HSR network; then it expands along the cross-provincial region; and is gradually embedded in the national HSR network, forming a figure-8-shaped spatial structure. (2) In the rapid expansion and densification of the HSR network in western China, connectivity takes precedence, and dominance and control are then increased. The external connectivity of the western HSR city network develops first and shows fluctuating growth, while the internal connectivity improves relatively slowly. (3) The connectivity, convenience of transit, transshipment capacity, and internal and external connection structure of the HSR network all contribute to the economic development of western cities. The transfer potential of economic gaps is detrimental to their economic development but has a positive effect on adjacent cities. [ABSTRACT FROM AUTHOR]

The authors have determined the economic effect of the introduction of computer-aided design systems for technological preparation processes in the machine-building industry. The research methodology is based on scientific heuristic methods and methods of functional analysis. The consolidated technical and economic indicators of the implementation of CAD TP were obtained, such as the average operating time of the system, the cost of CAD, capital investments, annual operating costs, the expected annual economic effect, the coefficient of economic efficiency, payback period. A methodology has been developed for calculating the economic effect from the introduction of CAD of technological processes, which differs from the methods by the lack of comparability of options for the identity of the results in the form of specific products. The author's vision of the terms of the economic effect from the introduction of CAD TP at mechanical engineering enterprises is proposed. The presented calculation method can be used in practice to determine the effectiveness of the creation and implementation of applied software products. The practical significance of the study lies in the adaptation of the software developed by the authors at machine-building enterprises. In the course of the research, the software was successfully tested and adapted, which is confirmed by the received certificates of implementation and title deeds. The duration of work during the technological preparation of those solved manually is 3.5 times longer than when working on a computer.

In the context of today’s society, intellectual property rights are an important source of economic benefits. When the infringement of these rights is done with regard to products or substances that also potentially endanger the environment and human health, research on these infringements becomes imperatively necessary. This paper highlights the dual effect of infringing intellectual property rights in the field of pesticides (both in economic and environmental terms, and on human health) and it draws attention to the need for multidisciplinary research to raise awareness among potential producers and users of such products.

This paper presents technological innovations based on new hydraulic insulating materials, the use of which in reservoir construction will essentially reduce construction costs by up to half. New polymer-mineral based waterproofing materials N1 and PMM can be used to construct inexpensive reservoirs. In particular, a thoroughly mixed mixture of soil taken from the bottom of a reservoir or other substrate with PMM material at a ratio of 30 grams PMM to one kg of the substrate, laid on the bottom of the reservoir with a thickness of at least 10 cm, and tamped down to a layer of 7 cm or less, will withstand at least 2.5-3 atm pressure of water column. A similar result can be obtained if a 5 cm thick layer of N1 material is laid on the reservoir bottom, together with pebbles to reduce the cost of the proposed solution.

The growing demand for freight and passenger transportation and the growing interest of the population in improving the speed, quality and safety of transportation require a new approach to the development of the railway complex, taking into account systemic trends in Russia and the global economy. In the longer term, it is necessary to reduce the transport costs of the national economy, ensure the accessibility of transport to entities, increase the competitiveness of transport services and solve the systemic problem of increasing the speed of freight and passenger trains. In recent years Russia has been discussing the development of the Baikal-Amur Mainline, which in Soviet times was a grandiose construction project of the era and an embodiment of the country’s power. However, there are a number of problems related to the weak socio-economic development of the regions. The Baikal-Amur Mainline was a grandiose construction project of the era and the epitome of the country’s power. The article pays particular attention to the further development of the Baikal-Amur Mainline.

Addressing issues related to the economic efficiency of biostimulants in agriculture meets the needs of farmers and consumer requirements. The urgency of this study is also determined by its compliance with the priorities of the European Union for the new CAP 2021+, in accordance with the national priorities for healthy food. Increasing plant productivity can be achieved, on the one hand, through genetics and selection, as well as through the management of physiological and biochemical processes through the use of growth regulators, on the other hand. The aim of this study is to evaluate the economic efficiency of biostimulants used in agriculture. The economic efficiency of the various biostimulants is established by solving the problem with the production structure of the agricultural holding. To establish the economic efficiency of the various biostimulants, an economic-mathematical model based on linear optimization has been developed. The results of preliminary studies show that in assessing the impact of biological substances it is necessary to take into account not only the increase in profitability and profit of a particular crop but also whether the profit of the farm as a whole has increased.

The aim of the work was to study the influence of rhizobacteria, arbuscular-mycorrhizal fungi and their combination on alfalfa seed productivity and the economic effect of their use. The research was conducted during 2018−2020 in a three-factor field experiment under different conditions of moisture (irrigated and non-irrigated) and three varieties of alfalfa under inoculation with bacterial and fungal preparations at the experimental field of the Institute of Irrigated Agriculture of the NAAS, located in the steppe zone of Southern Ukraine. In the first year of the life of the herbaceous plant, the seed yield under irrigation was 187.0 kg/ha, which was 83.5 kg/ha more than under natural irrigation conditions. Alfalfa cultivars also differed in seed yield. The minimum seed yield was obtained on the control variant (without inoculation) with irrigation - 147.9 kg/ha in the Unitro variety, 180.6 kg/ha in the Elehiya variety and 161.8 kg/ha in the Luyiza variety, while without irrigation 79 .9, 106.5 and 89.0 kg/ha, respectively. The highest seed yield was obtained by complex (AMF and Sinorhizobium) seed inoculation with Drugs 2 and 4. In the sum of two years, the lowest seed yield was also obtained by the control option (without inoculation) and amounted to 588.5 kg/ha when irrigated in the Unitro variety, of the Elehiya variety - 695.9 and 631.9 in the Luyiza variety, under natural moisture conditions - 386.5, 463.8 and 417.3 kg/ha, respectively. The highest seed productivity under complex inoculation (Drug 2 and Drug 4), which amounted to 715.7–725.7 kg/ha with irrigation in the Unitro variety, 842.2–864.0 kg/ha in the Elehiya variety and 769.9– 780.5 kg/ha in the Luyiza variety, while under conditions of natural moisture – 451.5–454.1 kg/ha, 534.9–547.2 and 485.4–488.0 kg/ha, respectively. The best indicators of economic efficiency were obtained with irrigation, namely the cost price was 1.30 €/kg, conditional net profit – 1,775.40 €/ha. The highest seed productivity was characterized by the Elehiya variety, which, when irrigated, had a seed cost of 1.19 €/kg, conditional net profit of 2,008.36 €/ha, under conditions of natural moisture 1.21 and 1,297.60, respectively. Among the inoculants, the lowest cost price and the largest conditional net profit were obtained with the use of drug 2, which amounted to 1.30 €/kg and 1,779.09 €/ha for irrigation in the Unitro variety, 1.10 €/kg and 2,288.00 for the Elehiya variety €/ha and 1.21 €/kg and 1,980.88 €/ha in the Luyiza variety. Under conditions of natural moisture, the values of these indicators in alfalfa varieties were: 1.39 and 1,074.06, 1.16 and 1,416.63 and 1.29 €/kg and 1,198.69 €/ha, respectively. Inoculation of seeds with fungal and bacterial drugs contributed to the increase of seed productivity, regardless of the year of life of the grass stand, variety and moisture conditions. However, the highest seed yield, and correspondingly the lowest cost and the highest profit, was obtained by complex (AMF and Sinorhizobium) seed inoculation. [ABSTRACT FROM AUTHOR]

The Indian poultry market is estimated to have an annual growth rate of 8.1% as of today. However, infectious diseases in poultry pose an important constraint in the growth and development of this sector in our region. Among infectious diseases, viral diseases of poultry pose a serious threat to the poultry industry from an economic point of view. Several viral disease outbreaks have been reported by various researchers from different parts of the country. Among the common viral diseases of poultry, incidences of Newcastle disease, Avian Influenza, Fowl Pox, Infectious Bursal Disease, Marek’s disease, Infectious Bronchitis, Infectious Laryngotracheitis and Inclusion Body Hepatitis are significant in Assam as well as other parts of India. Thorough epidemiological studies followed by the identification of different serotypes, pathotypes, strains, etc. by genotyping and molecular characterization of viral disease pathogens may lead to ways to control and eradicate the diseases. Importance should be given to maintaining basic preventive measures like biosecurity, farm hygiene, and proper vaccination. In a developing country like India, disease outbreaks can impact the country’s economy. In this study, a brief view of the common viral disease of poultry and its diagnosis and control strategies in Assam, India is depicted. However, this review well indicates a plethora of avian diseases that have occurred over the years causing a severe impact on poultry farming as a whole. [ABSTRACT FROM AUTHOR]

For farmers, the more fragile the state of the ecology becomes, the more their awareness of the need for environmental protection grows. China’s Grain for Green Project (G.G.P.) policy of returning farmland to forests and grassland, as an external shock to the environment, has sparked people’s ecological aspirations. Many people have noticed the phenomenon of ecosystem degradation and overlapping poverty. Analyzing the environmental and income changes brought about by the G.G.P., and this study considers farmers’ self-selection problems due to their lack of subjective thinking regarding this initiative. Our study aims to fill this gap by using a forest–grass model to assess the level of farmers’ ecological aspirations in ecologically vulnerable areas of Xinjiang, China. This article is based on aspiration theory and a theoretical model assessing the economic impact of ecological aspiration on the G.G.P. in China. The results show that farmers’ ecological aspirations can increase their enthusiasm to participate in the G.G.P. Under counterfactual conditions, participation in the G.G.P. initially reduces farmers’ total income to a certain extent; however, in the long run, it can significantly increase the total income of farmers. When the intermediary effect is used to analyze the economic effect of ecological aspiration on returning farmland to forest, it is found that farmers’ ecological aspirations affect household income by influencing income expectations. Our findings have essential practical implications and provide an important reference for consolidating poverty alleviation efforts and effectively promoting rural revitalization. In addition, the results suggest a way to achieve the goals of carbon peak and carbon neutrality, and it is necessary for building environmental-friendly regions.

Mart 2011’de Suriye’de meydana gelen savaş neticesinde ülkelerini terk edip komşu ülkelere sığınan Suriyelilerin en çok tercih ettiği ülkelerden biri de Türkiye’dir. Savaşın uzun süre devam etmesinin de etkisiyle ülkemizde hızla artan Suriyeli sayısı sosyal, siyasal, ekonomik ve kültürel olarak birçok açıdan ülkemizi etkilemiştir. Bu çalışmamızda tekstil şehri olarak bilinen Denizli iline sığınan geçici koruma altındaki Suriyelilerin Denizli’ye etkileri ekonomik yönden analiz edilmiştir. Çalışmamızın sonucunda, Suriyelilerin olumsuz vergi algısına neden olduğu ortaya çıkmıştır. Bununla beraber kamu harcamalarını, kayıt dışılığı ve işsizliği artırdığı sonucuna ulaşılmıştır. Ayrıca kadınların ve eğitim seviyesi yüksek olan katılımcıların Geçici Koruma Altındaki Suriyelilerin çalışma hayatına katılımlarını daha çok destekledikleri tespit edilmiştir.

The contradiction between China's economic development and the reduction of carbon emission is increasingly deepening along with the complex carbon emission transfer. Optimizing provincial-level carbon emission transfer in China is important for facilitating economic development and carbon emission reduction. Under these dual constraints, this study uses the slacks-based measure, marginal abatement cost, and geographically and temporally weighted regression models to measure the economic and carbon emission reduction effects and the carbon emission reduction baseline. Then, the optimization strategy and path of provincial carbon emission transfer network structure are proposed to provide policy support for achieving the dual goals of economic development and carbon emission reduction in China. This article draws the following important research conclusions. First, under the three economic development scenarios, provinces in the eastern coastal developed regions are capable of completing the expected carbon emission reduction, whereas the underdeveloped provinces in the central and northern regions are not. Second, from the perspective of the economic effect of carbon emission transfer, carbon emission transfer from most provinces promotes economic development, whereas carbon emission transfer from a few economically underdeveloped provinces hinders economic development. Third, from the perspective of the carbon emission reduction impact of carbon emission transfer, carbon emission transfer in the northeast region has a negative impact on carbon emission reduction, and carbon emission transfer in developed regions also has a negative impact on carbon emission reduction. Fourth, the optimization of the carbon emission transfer can be divided into four categories. [ABSTRACT FROM AUTHOR]
