With the development of the market economy, agricultural trade has become more and more significant for the development of the agricultural economy, which has triggered people's further thinking and exploration on the impact of agricultural trade on agricultural carbon emissions. This paper takes the measurement of trade implied carbon as the carbon dioxide emission index under the impact of agricultural trade and analyzes the impact of trade implied carbon and implied carbon balance on carbon emission. Taking the impact of Sino-US agricultural trade as an empirical background, this paper measures the impact of environmental changes in agricultural trade opening on China's agricultural development and its carbon emissions, so as to predict changes in China's regional agricultural carbon emissions performance. After calculation, it is found that the scale of China's exports has decreased by 0.089%, which is lower than the decline of 0.361% in the United States. The trade conflict has a significant impact on China's import and export structure. Under the scenario of mutual tariffs on agricultural products, China's exports to the United States are expected to decrease by 6.28%, while China's imports from the United States decreased by 13.02%. The Sino-US agricultural trade dispute will reduce China's carbon emissions by 0.013% and the United States' carbon emissions by 0.024%, which is related to the negative impact on the economy. Improving the performance of agricultural carbon emissions is not only the need for the green and sustainable development of the agricultural economy but also conducive to improving the international competitiveness of agricultural products.

In recent years, the new agricultural business entities have grown rapidly in all parts of the country and have become an effective carrier to achieve the basic stability of China's rural family operation system and moderate-scale agricultural operation. However, the systemic defects of rural financial market and the credit rationing of formal financial institutions make the capital needs of rural areas unsatisfied for a long time. Financial demand determines the direction of supply reform. Therefore, in order to improve rural financial supply and promote the transformation and development of agricultural economy under the current situation, it is necessary to effectively understand the formal credit demand and the impact factors of accessibility of the new agricultural business entities, which represents the direction of China's agricultural development in the future. Based on back propagation (BP) neural network, this paper constructs the farmers' formal credit availability prediction model and studies the formal credit demand and the impact factors of the availability of new agricultural business entities. The experimental results show that the farmers' formal credit availability prediction model has good performance in prediction accuracy, prediction time, and mean squared error.

In the era of "Internet+," the increase of agricultural products sales can be achieved by creating and joining e-commerce platforms. Most of the farmers in China are self-employed and cannot form an industrial scale. With the rise of "Internet+" background research, the combination of this technology and the marketing of agricultural products has become a new marketing model under the deep integration of different fields. Based on the marketing of products under the background of "Internet+" and using marketing theories, this paper reviews the development of marketing of agricultural products under the background of "Internet+," including the Internet infrastructure, the establishment of logistics system, the formation of branding, and the deep processing of agricultural products. The paper reviews the development of agricultural marketing under the background of "Internet+," including the Internet infrastructure, establishment of logistics system, branding, and deep processing of agricultural products. The marketing mode of agricultural products under the background of "Internet+" is proved, and the development of agricultural products marketing under the background of "Internet+" is discussed from various angles, and insights into how to improve it are proposed from five aspects. After excluding the influence of environmental factors through the improved three-stage SE-DEA model, the mean value of TE of comprehensive efficiency of agricultural information allocation increases from 0.773 to 0.832, the mean value of SE of scale efficiency increases from 0.844 to 0.9219, and the mean value of PTE of pure technical efficiency adjusts from 0.9087 to 0.9058. The mean value of pure technical efficiency (PTE) was adjusted from 0.9087 to 0.9058. Compared with the parametric method, DEA does not require a specific production function to be set in advance, and it is also difficult to select a suitable production function in advance for complex problems.

With the rapid development of agricultural economy, people are paying more and more attention to how to apply high-efficiency technologies that save resources to improve agricultural production efficiency, so water-saving irrigation technology has gradually developed. China's agricultural irrigation technology is relatively backward. In addition to the inappropriate irrigation methods and irrigation systems, problems such as siltation, seepage, and frost heave damage in irrigation canals have seriously affected the durability and service life of the canals. The backward irrigation technology seriously restricts the development of agricultural water-saving irrigation. Compared with large irrigation channels, the fabricated reinforced concrete small irrigation channels studied in this paper are less prone to frost heave damage and infiltration problems, and have the advantages of standardized production, simple transportation and installation, and convenient maintenance. In order to study the durability issues such as the basic characteristics, frost heave damage, and service life of fabricated irrigation channels, this paper takes the channel concrete and the formed channel as the research objects, and discusses the research on the properties of the channel concrete through theoretical research, numerical analysis, experiments, and other methods. Strength properties, water penetration resistance, cyanide ion penetration resistance and frost resistance; simulate the seasonal frost heave failure process of the channel; finally, on the basis of the test data, the service life aims to explore the safety and applicability of the fabricated reinforced concrete irrigation channel during the design use period.

Agriculture is particularly essential in the equilibrium between man and nature because of its intimate contact with nature. So the cornerstone for the sustainable development of the human economy and society is the sustainable development of agriculture. When it comes to global trade, agricultural trade has always been in a very special position. The basic situation of agriculture involves food safety, environmental protection, Chinese politics, and many other issues. In order to overcome the problems of overlapping, repetitive, and too many indicators in the evaluation method of agricultural environmental sustainable development and unfavorable for practical operation, this paper proposes an ecological footprint model based on emergy. The model can effectively evaluate the ability of sustainable development of agricultural environment and solve the problem that traditional evaluation methods cannot comprehensively evaluate. This makes agricultural development sustainable and is conducive to the liberalization of international agricultural trade. The experimental results of this paper show that from 2014 to 2018, the degree of damage to the agricultural environment has increased from 21% to 45%, which has led to a decline in the quality of agricultural products, and the output and sales are not as good as before. It can be seen that only by ensuring the sustainable development of the agricultural environment can we ensure the smooth progress of the international agricultural trade liberalization and make China's economy flourish.

International environmental law is the basic charter for dealing with international environmental issues, and it plays an important role in international environmental governance. In recent years, China's economy has achieved great development, but environmental problems are also very prominent. International environmental law provides a basic reference for China's environmental governance, but it also brings challenges to the development of China's environmental productivity to a certain extent. At the same time, due to the unique dominant position of international environmental law, it has played a certain restrictive role in the development of China's environmental productivity. Based on this, in order to promote the sustainable development of China's economy, this paper took China's industrial and agricultural development as the research object. This paper has conducted research on China's industrial and agricultural environmental productivity, aiming to explore the role of international environmental law in China's environmental productivity. The article first analyzed the limitation of international environmental law on China's environmental productivity, and then on this basis, the article conducted a numerical simulation of China's industrial and agricultural environmental productivity. Finally, starting from the actual development situation, the paper aimed to find out the numerical deviation of China's environmental productivity changes through quantitative analysis. In the course of the research on environmental productivity development, the article found a strong correlation between environmental productivity and international environmental law in China. The correlation between environmental productivity and international environmental law reaches 59.93% in South China and 61.02% in North China. Also, after a series of comparative analyses, the article finds that changes in climate characteristics can exacerbate the regulation of China by international environmental law and seriously affect China's economic development. In this case, China's economy declined by 2.6% year-on-year, which further pushed China to practice sustainable development strategies. This shows that it is essential to study the relationship between international environmental law and China's environmental productivity. [ABSTRACT FROM AUTHOR]

Then, we use the analytic hierarchy process (AHP) to calculate the index weight and take Shanxi Province of China as the research object to evaluate and analyze the development level of APEC. The evaluation results show that the overall development of APEC in Shanxi Province is at a general level. Finally, we put forward some suggestions for the development of APEC, such as improving the standardization system of APEC. [ABSTRACT FROM AUTHOR]

The green development of the entire agricultural industry chain is not only an important way to enhance the competitiveness of agricultural products and promote the value-added of the agricultural industry but also an inevitable choice to improve the efficiency of resource utilization and ensure sustainable economic development from the perspective of the ecological environment. This paper defines the connotation and characteristics of the green development of the whole agricultural industry chain and deeply analyzes the development status, major challenges, and feasible paths of the whole agricultural industry chain in China. It has built a whole industry chain development model of "Internet + modern agriculture" and proposed a decentralized agricultural data management system based on the IoT to solve the problem of untraceable of traditional agricultural products and other data. The agricultural IoT system is designed with a unique blockchain double-chain structure, using the global hash chain and the mutual verification between the transaction chains in each partition. It proposes the PMCP protocol, which improves the performance of the system by producing blocks in parallel for several consensus groups in each consensus cycle. The experimental results show that the proposed model is queryable, traceable, and trustworthy for whole-life agricultural data, and the proposed model outperforms other schemes in terms of throughput and delay.

China is a large agricultural country. With the development of industrial production, mechanized harvesting has become an inevitable development trend of agricultural material harvesting. In this paper, based on the latest technology of polycrystalline ferroelectric composite materials in the design of the shovel frame of the harvester's vibrating excavating shovel, the relevant theories of the polycrystalline ferroelectric composite material and the shovel frame of the harvester's vibrating excavating shovel are based on the literature. After understanding, the shovel frame structure of the vibrating excavating shovel of the harvester was designed, and the latest technology of polycrystalline ferroelectric composite material was introduced in the design of the shovel frame of the vibrating excavating shovel of the harvester to make the vibration system have better performance. The designed shovel frame structure is tested, and the test results show that the horizontal output force received by the shovel designed in this paper increases with the increase of speed and is minimized at 0.26 m/s. The vertical output force decreases first and then increases with the increase of speed. It is the smallest when the running speed is 0.39 m/s. The horizontal working resistance is always greater than the vertical working resistance, and it can be seen that the design of the shovel frame structure can be realized in actual work.

With today's rapid economic growth, the role of agriculture in production and life has come to the forefront. Many problems in China's agricultural economy have seriously constrained the vitality of Chinese agriculture. Therefore, it is necessary to further strengthen the study of an agricultural economy, inject new impetus into an agricultural development, develop targeted solutions, and lay a solid foundation for the sustainable development of China's agricultural economy. Therefore, in this paper, based on the theory of sustainable development of an agricultural economy, this paper constructs a sustainable agricultural development index system in Jiangsu province from five aspects of the DPSIR model: driving force, pressure, state, impact and response and uses principal component analysis to make a comprehensive evaluation of the level of sustainable agricultural development in Jiangsu province from 2010 to 2016. The analysis results show that Jiangsu's agricultural economy is overall better and steadily improving, and it has made a huge leap in the seven-year period from 2010 to 2016, showing better sustainability. We found that the state subsystem exposed some social problems after analyzing the subsystem, and if relevant measures are not taken in time to solve the emerged problems, it will affect the other subsystems and the sustainability of the agricultural economy.

Based on the data of 30 provinces in China, the super-efficiency EBM model is used to calculate the agricultural ecological efficiency in China, and analyze the impact of different environmental regulations on the agricultural ecological efficiency. The results show that: China's agricultural ecological efficiency is not optimal. Specifically, the main grain production areas and grain balance areas have not reached the optimal efficiency, and the main grain sales areas have basically reached the optimal efficiency. In addition, among the influencing factors, the influence degree of different environmental regulations is well distinguished, which is the focus of this paper. We can find that command control environmental regulation and market incentive environmental regulation have a significant positive effect on different regions. Among them, market incentive environmental regulation has a significant positive impact on the agricultural ecological efficiency of the whole country and the grain balance areas. Command controlled environmental regulation has a significant positive impact on the agricultural ecological efficiency of the whole country and the main grain producing areas. So, it is necessary to formulate environmental policies according to the actual needs of development. [ABSTRACT FROM AUTHOR]

The agricultural mechanization development can promote the high-quality development of agriculture, but the agriculture which faces the huge environmental pressure also needs to transform to the green sustainable development. Based on agricultural panel data of 30 provinces in China from the year 2008 to 2017, this paper measures the level of agricultural green transformation using the Malmquist–Luenberger (ML) index. Furthermore, the spatial panel econometric model is used to empirically investigate the impact of agricultural mechanization development on this green transformation. It concludes that the agricultural green transformation in western China shows an upward trend in fluctuations, with its overall transformation level still lower than the national average level. Besides, the agricultural mechanization operation level in the western region has a positive role in promoting the green transformation of agriculture, while the agricultural mechanization equipment level shows the opposite force. Compared with southwest China, the agricultural mechanization operation level in northwest China has a more positive impact. The improvement of farmers' income and agricultural technology has positive impacts on agriculture green transformation in the whole western region, while agricultural human capital shows an opposite impact on the northwest and southwest.

Agricultural modernization has gradually become the direction of future agricultural development. With the improvement of the technical capacity of the Internet of things, a new agricultural development model, namely, intelligent agriculture, has gradually emerged. It can not only improve the production efficiency of agriculture but also improve the efficiency of resource utilization. The main work of the software design of the terminal node is the IoT network connection, the sensor work acquisition, and the packaging of the collected data for transmission and acceptance control to fundamentally alleviate the pressure on food security and ensure the sustainable development of China's agriculture. The experiment demonstrates that the curve temperature cycle of the agricultural greenhouse monitored by the system in this paper is normal, and the maximum temperature has been constant under different time cycles. For example, the maximum values of 5, 15, and 20 are all 0.67. [ABSTRACT FROM AUTHOR]

Land use change plays an important role in regional socio-economic development and global environmental change. Whether the land is effectively and efficiently used is not only related to the income level of the people in the surrounding cities but also closely related to the local economy and national economy. Intelligent environment refers to the indoor environment with a variety of data acquisition equipment. Combined with related technologies, the reasoning and analysis of the data can be used to realize the functions of activity identification, data perception, and control. In addition, the Yangtze River Delta is an economically developed area in China, and its land use situation is related to the economic development in the next ten or even decades. Therefore, it is necessary to analyze the spatial and temporal pattern of land use in Yangtze River Delta region by remote sensing image technology and GIS in intelligent environment. Based on intelligent environment, this paper uses RS and GIS technology to interpret remote sensing image and map land use in multitemporal coastal zone. The land use dynamic degree model and spatial interpolation method were used to analyze and evaluate the spatial and temporal evolution characteristics of land use in the Yangtze River Delta region, and the landscape pattern changes in the Yangtze River Delta region were analyzed and evaluated. This study found that the land use types in the Yangtze River Delta have transformed each other, and the land use change speed is fast, which is inseparable from the rapid economic development. In the future, in addition to maintaining the rapid and stable development of industry, the rational use of limited land resources, the improvement of agricultural development short board, and the improvement of tourism economic benefits will make the economy of the Yangtze River Delta region to a new level.

Risk assessment of drought disaster is necessary for the sustained agriculture development under the background of global climate change, and, meanwhile, it is an urgent scientific issue needed to be solved in agricultural risk assessment discipline. In this paper, collecting the areas covered by drought disasters, areas affected by drought disasters, areas with no harvest by drought disasters, areas planted, and yield per unit area data, agricultural drought disasters losses of the southern five provinces in China were calculated. The best probability density function was obtained according to the goodness of fit test results. Then, the value at risk (VaR) from financial market risk research method was used to the effective measure of agricultural drought risk. The results show that, in southern five provinces of our research region, risk of agricultural drought disaster in Yunnan and Guizhou is greater than other three provinces. In the scenario of 50 years and 100 years for a return, the crop loss caused by drought will reach 13.6% and 17.4% in Yunnan province, and the crop loss will be more serious in Guizhou province and be up to 15.3% and 18.1%. The above results can provide multifaceted information about drought risk that can help to guide management of drought disasters. [ABSTRACT FROM AUTHOR]

Synthetic aperture radar (SAR) is a new high-tech radar that uses SAR principles and pulse compression technology to perform high-resolution imaging of ground targets. Because it is not affected by various factors such as location, time, and climate, it is widely used in the civilian and military fields, bringing huge social and economic benefits. Moreover, the environment of agricultural water resources and the development of regional agricultural economy can be studied using the SAR imaging algorithm. With the serious shortage of water resources and the increase of the world's population, the use of water resources for agriculture must not only achieve the goal of saving water, but more importantly, achieve efficient production on the premise of saving water. However, the shortage of water resources in China has become a serious constraint on the development of agriculture and rural economy and has become an important factor restricting the sustainable development of agriculture and rural economy. Therefore, the development of efficient and sustainable use of water resources is very important to establish a water-saving society for the sustainable development of China's economy and society. For the spaceborne SAR system, an azimuth-based multi-channel range ambiguity suppression method is proposed in this chapter. The simulation results show that after adopting the azimuth phase encoding technology, the azimuth spectrum of the signal in the ambiguous area can be moved to suppress the distance ambiguity.

At this stage, the promotion of China's agricultural revitalization plan has provided new demands for the development of agricultural construction. In the process of urban and rural planning, more and more attention has been paid to the protection of rural traditional culture and aesthetic values, as well as the requirements of characteristic aesthetics. In recent years, as we pay more and more attention to the environmental protection ability and aesthetic ability of rural life, we also pay more attention to improving the rural environment, promoting rural rejuvenation, and paying attention to shaping the livable space quality of rural living environment to meet the needs of modern life and soul. "Beautiful countryside" is one of the modern development concepts explicitly put forward by China, which advocates the harmonious symbiosis aesthetic idea of "harmony between man and nature." Building a beautiful countryside is the key point of rejuvenating the countryside, and the exploration of rural aesthetics is also the important significance of realizing the great rejuvenation goal of China's rural areas. Environmental design in the construction of "beautiful countryside" is a major decision and historical task for building a new countryside in China, and building landscape design suitable for the needs of rural development is the current requirement of social development. The article firstly analyzes the challenges and opportunities of China's "beautiful countryside" environmental construction; secondly, by digging into the philosophical ideas of deep ecology, ecological aesthetics, and the relationship between man and land in the West, it analyzes the application strategies and practical methods of these practical philosophies. It provides corresponding theoretical and practical enlightenment for my country's "beautiful countryside" environmental design strategy. [ABSTRACT FROM AUTHOR]

In recent years, China's Internet industry has developed rapidly, and the Internet has penetrated into all aspects of people's daily lives. As an emerging transaction model, rural e-commerce is an important channel for precise poverty alleviation. To be specific, rural e-commerce can greatly change the lives of rural people in one way or other ways, thus allowing rural consumers to purchase high-quality and inexpensive goods without having to leave home. In other words, the introduction of national e-commerce into rural areas has changed the lifestyle of rural residents, providing them with great convenience in their daily lives. According to statistics, the level of rural e-commerce development in coastal areas is much higher than that in the mainland, while inland areas are hesitant to develop. Rural areas are a crucial component of Chinese society, and the rural economy is also the main driving force of China's agricultural economy. In an environment where e-commerce is gradually penetrating various fields, the development of rural e-commerce in China has become more urgent with the new and growing rural demand. To be specific, the development of rural e-commerce has become a hot topic in recent years, and it is necessary to gather efforts from all sides to explore and innovate, so as to promote the healthy and orderly growth of rural e-commerce in China. As one of the effective ways to solve the problems of agricultural industry development and farmers' affluence, rural e-commerce has played an increasingly obvious role in industrial development, poverty alleviation, employment, and solving the problems of selling agricultural products. At the same time, the proportion of national online sales of agricultural products is also increasing year by year. Many rural areas have abundant natural resources, rich history and culture, and a pleasant ecological environment. As a result, a great number of rural areas are well suited for e-commerce development in terms of the overall environment and physical resources. In recent years, the development of rural e-commerce in China has been very rapid, but it has also revealed many problems. Therefore, an in-depth study of the regional factors affecting the development of rural e-commerce is helpful to provide a reference for its better development. Based on the analysis of the current situation of rural e-commerce development, this study collects and organizes the indexes of influencing factors of rural e-commerce. The index system of influencing factors of rural e-commerce development is constructed through data collection and so on. After that, this study adopts the regional fuzzy information theory to evaluate the potential of rural e-commerce development, so as to obtain the main influencing factors of rural e-commerce development.

The IoT applications in the agriculture industry are intertwined in many ways, creating a hybrid construct of traditional businesses with digital connectivity implementations. Strategic issues and principles on the assimilation of IoT solutions are prevailed through time: investment costs, data interconnectivity, management, and analysis, as well as data security. As the first international organization in which China is the founding country, the Shanghai Cooperation Organization provides strategic support for China on the international stage. At present, there are various issues on the bilateral trade in agricultural products. Realizing the high-quality development of agricultural products trade with SCO member states is of great significance in forming a new pattern of sustainable and healthy development of bilateral agricultural product trade cooperation during the "14th Five-Year Plan" period, promoting the joint construction of "a community of shared future for Shanghai Cooperation Organization." On the basis of analyzing the status quo of bilateral agricultural trade from 2011 to 2019, the influence of various influencing factors on the high-quality development of bilateral agricultural trade is empirically analyzed based on the gravity model. The study found that the overall quality of agricultural trade between China and the SCO member countries has shown a fluctuating upward trend with a larger development space. The size of the market, the level of trade facilitation, and the degree of trade openness and trade structure in each country have a significant role in promoting export value of China and other countries.

China is a large developing country, and there is no doubt that it is a large developing agricultural country. Agriculture has played a vital role in the development of the national economy since ancient times, and it serves as the foundation of China's national economy. As agricultural modernization is the fundamental way of agricultural development, its source of funds must come from rural finance. The financial support of rural finance for agricultural modernization is the material basis and prerequisite for ensuring the healthy and rapid development of agricultural modernization. If there is no financial support from rural finance, the process of agricultural modernization will be hindered, and it will not benefit our country's socialist modernization. Although our country's rural financial system has been constantly changing and improving, our country's current financial system still has many shortcomings and defects. In the process of supporting agriculture, rural finance has insufficient capital supply, which has become a "bottleneck" in the development of agricultural modernization, and to a certain extent has severely restricted the development of agricultural modernization. On the basis of existing literature research, this article systematically studies the influence of rural financial market structure on the development of agricultural enterprises in central China. The content includes agricultural total factor productivity and agricultural emission reduction. When analyzing the impact of rural financial market structure on agricultural development, this article also pays attention to its specific impact on agricultural development under the conditions of different types of enterprises.

China Internet plus rural industrial integration is applied in the era of agricultural informatization in the era of Internet plus urban integration strategy. For many years, the themes of urban-rural integration, agricultural economy, and rural revitalization have been the core topics of China's economic research. This study fully integrates the above elements and analyzes the development path of rural economic informatization in China's special environment. Supported by the national strategic direction and related policies such as the integration of urban and rural areas, Internet plus agriculture, agricultural informatization, and rural revitalization, we hope to achieve faster agricultural economic development through the rational optimization of agricultural economic integration and supervision and promotion programs and the use of the existing information platform. The problems of China's agricultural economic development caused by historical reasons are thoroughly solved. China's regional agricultural economy should not only be not limited to the large-scale and intensive development of planting, animal husbandry, forestry, and fishery in the primary industry but also should realize the integration of urban and rural areas under the background of economic informatization, develop the secondary and tertiary industries related to agriculture in the agricultural economic zone, let the agricultural economy get rid of the constraints of the development ideas of the primary industry, and let the high value-added characteristics of the secondary industry and the tertiary industry fully contribute to the development of agricultural economy.

Water resources in the Yongding River basin (YRB) are one of the important fundamental conditions in supporting regional water conservation and ecological development. However, the historical changes in water resources under recent human activities remain unknown due to very limited observation data. In this study, terrestrial water storage anomalies (TWSA) as well as multiple precipitation and actual evapotranspiration products from satellites were collected, and the accuracy of the data was verified by observed data or pairwise comparisons. The TWSA during 1980-2016 was reconstructed by using the water balance method, and the reconstructed TWSA was verified using GRACE-observed TWSA, the average depth to groundwater in the Beijing Plain from historical document records and the observed runoff from Guanting Reservoir. The reconstructed TWSA data indicated that the significant decrease occurred during 2000–2016 and the average rate of decreasing trend was -11 mm/year, which may have been caused by a decrease in groundwater storage due to agricultural development. However, the reconstructed TWSA decreased slightly during 1980-1999. The establishment of the water storage deficit index (WSDI) showed that there was no drought or mild drought during 1980-1999; however, the water resource shortage during 2000-2016 was more serious due to groundwater storage decreases caused by agricultural development. The WSDI was verified by using the commonly used self-calibrated Palmer drought severity index. The findings are valuable for sustainable water resource management in the YRB. [ABSTRACT FROM AUTHOR]

The output values for agriculture, forestry, animal husbandry, and fishery are important indicators of agricultural economic development. Therefore, accurately predicting the output values for agriculture, forestry, animal husbandry, and fishery can capture the developmental trend and the optimize the structure. Agriculture, forestry, animal husbandry, and fishery are typical seasonal industries, and thus their output values vary greatly among different seasons. To accurately estimate the seasonal variations in the observed sequence and obtain better prediction results, the output values for agriculture, forestry, animal husbandry, and fishery in different quarters from 2018 to 2021 are predicted and analyzed by using the grey seasonal model (GSM). The results indicated that the prediction accuracy of GSM is relatively high. The output values for the agriculture, forestry, animal husbandry, and fishery as well as their total output value will increase gradually. It is an important achievement of structural reform under the new normal economic situation. In addition, the GSM provides a new method for predicting seasonal data. [ABSTRACT FROM AUTHOR]
