Environmental pollution control is one of the key manifestations of driving high-quality economic development. Whether different factor-biased technological progress is conducive to the reduction of environmental pollution and what role environmental regulation plays in it deserve further investigation. Based on the panel data of 30 provinces in China from 2005 to 2020, this study adopted the stochastic frontier model to measure the index of biased technological progress and used the spatial Durbin model to investigate the spatial spillover effects of labor-energy-biased technological progress and capital-energy-biased technological progress on environmental pollution, as well as the moderating effect of environmental regulation. The results showed that: (J) From 2005 to 2020, China's technological progress as a whole was biased towards the use of capital, energy, and labor conservation and was shifting towards energy conservation. © Biased technological progress could directly reduce local environmental pollution and indirectly improve the environmental quality of neighboring areas, with spatial spillover effects on the impact of environmental pollution. Among them, labor-energy-biased technological progress had a significant negative impact on local environmental pollution, and capital-energy-biased technological progress had an inhibitory effect on the environmental pollution of both local and neighboring areas and could effectively improve ' local-neighboring ' environmental quality. © Environmental regulation played a significant positive moderating effect on environmental pollution in the impact of capital-energy-biased technological progress, enhanced the inhibiting effect of capital-energy-biased technological progress on the environmental pollution of local and neighboring areas, and the two showed better adaptability, inducing technological progress to be biased towards energy conservation and stimulating the development of ' local-neighboring' environmental quality. ® Biased technological progress inhibited environmental pollution in both coastal and inland areas, but the inhibition effect was better in coastal areas than inland areas. Environmental regulation in coastal areas had a stronger moderating effect on the pollution abatement effect of biased technological progress than that in inland areas, and it was easier to induce technological progress in coastal areas to favor energy conservation to reduce environmental pollution. To enhance the pollution abatement effect of biased technological progress, it is necessary to increase the research and development of green technology innovation, encourage enterprises to adopt clean technology production, formulate reasonable environmental regulation policies, pay attention to the appropriateness of the direction of technological progress, and establish a regional cooperative mechanism.

In order to better reflect the regional sustainable development capacity, we take the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) as the research region, and a set of emergy ecological footprint model, which is based on energy flow combined with remote sensing technology, is applied to accurately evaluate the evolution of emergy carrying capacity, emergy ecological footprint and environmental pressure in this region. In addition, we also use the decoupling model and Logarithmic Mean Divisia Index (LMDI) decomposition model to further reveal the impact degree and mechanism of economic growth mode on environmental pressure. Results show that: 1) the environmental pressure of the GBA has tripled over the past 25 years, and the ecological security level has gradually changed from sub-security to slight insecurity on the regional scale. 2) On the urban scale, Zhuhai has the lowest environmental pressure among the 11 cities, and its ecological environment has been kept in the status of security during the study period. While Foshan has a high environmental pressure, and the status of ecological environment has even deteriorated from severe insecurity to extreme insecurity. Besides, the greatest difference of ecological security level is occurred in Huizhou, which has changed from security to slight insecurity. 3) The evolution of ecological security level is closely related to the changes of industrial structure and energy structure, while the relationship with economic growth has experienced a process from weak decoupling to expansive negative decoupling, then to weak decoupling and finally to strong decoupling. It can be seen that the effect of environmental pressure is gradually weakened by economic growth, which is mainly due to the population effect caused by the decline of population density and the technology effect brought by the technological progress. Consequently, the sustainable development level of the GBA can be effectively improved by reasonably controlling the expansion of construction land, vigorously developing science and technology, releasing population pressure, and seeking the maximization of economic, social and ecological benefits in the future.

The marginal abatement cost of CO2 emissions can reflect the relationship between environmental quality and economic growth. It is not only the scientific basis of climate policy-making but also the key factor to achieving the dual goals of reaching peak carbon emissions and carbon neutrality. Based on three behavior patterns of the directional distance function, this study constructed three calculation methods of the marginal abatement cost of CO2 emissions, measured the three kinds of marginal abatement cost of CO2 emissions of 30 provinces (excluding Tibet, Hong Kong, Macao, and Taiwan) in China from 1998 to 2019, and analyzed them from the national, regional, and provincial levels. Furthermore, this study constructed the theoretical framework of the impact mechanism of the marginal abatement cost of CO2 emissions from the perspectives of emission reduction space and technological progress and carried out empirical tests. The calculation results showed that: (1) The marginal abatement cost of economic entities from the ' traditional-weak' mode was mostly negative; that from the ' traditional-strong' mode was mostly close to zero; and that from the ' weak-strong' mode was positive. (2) Under the three measurement methods, the marginal abatement cost showed an ' N'-type curve of increase, decrease, and then increase. The regional laws were consistent, which were higher in the central region and lower in the eastern and western regions. And the marginal emission reduction cost of the same kind varied greatly between different regions and provinces. Further analysis of the impact mechanism showed that: ( Emission reduction space and technological progress were the two most important factors affecting the marginal abatement cost of CO2 emissions, which played a leading role successively. (3) Only when there was plenty of room to reduce emissions, the economic actors were in the stage of extensive development, and policies on energy conservation and emission reduction were in the initial stage, could policies on energy conservation and emission reduction reduce the marginal abatement cost. (4) Technological progress appears to be cyclical. China' s green technology is now in the initial growth period of rapid development, and technological investment is in the sunk cost stage. Although the space for emission reduction could force technological progress, technological progress could hardly reduce the cost of emission reduction. Therefore, in the formulation of emission reduction policies, we should pay attention to phased and regional differences; continue to promote and improve the carbon emission trading market; consider the characteristics of ' silent fermentation' in the early stage of technological progress; and coordinate and promote sustainable development when undertaking industries in the central and western regions.

Does Internet development promote urban green innovation in cities? Previous studies have conducted many useful discus⁃ sions on the relationship between Internet development and urban innovation, but few have provided insights from the perspective of green development. It is well known that the continuous development and popularity of the Internet and other new-generation informa⁃ tion technologies can both promote technological progress and become the key to the transformation of regional economic growth. Start⁃ ing from a patent perspective, this article empirically analyzed the impact of Internet development on the level of green innovation in Chinese cities and its mechanisms of action using a two-way fixed-effects model and a mediating-effects model based on panel data of 285 prefecture-level cities in China from 2005 to 2019, based on a systematic review of the impact mechanisms of Internet development and urban green innovation. The results showed that: ① Internet development had a significant promotion effect on urban green innova⁃ tion, and the promotion effect on green invention patents was more obvious compared with green utility model patents. The results re⁃ mained robust after a series of robustness tests, such as endogeneity discussion and replacement variables, to conduct the regression analysis again. ② Further mechanism tests found that Internet development mainly contributed to green innovation by reducing transac⁃ tion costs and improving technology research and development. ③ The results of the heterogeneity analysis showed that, under different geographic locations and city sizes, the promotion effect of Internet development on the level of green innovation in central and western regions and large cities was more significant, while the promotion effect on eastern regions and smaller cities was average. Therefore, in the new era of China' s economic development transformation, we should not only encourage the application of the Internet to a variety of socio-economic fields and promote innovation development with the integration of various industries, but also improve the indepen⁃ dent innovation capability of Internet technology and pay attention to both the exploitation of innovation resources and the quality of in⁃ novations, so as to better tap the regional green innovation potential and improve information technology to achieve long-term and sus⁃ tainable development.

In this study, we used the stochastic frontier analysis (SFA) model in the form of the transcendental logarithmic function to analyze the major grain-producing areas in the Songhua River, Yellow River and Yangtze River basins from 2004 to 2018 under environmental constraints, in order to explore the influencing factors and quality dynamics of agricultural green development in major grain-producing areas based on agricultural green total factor productivity (GTFP) . The results showed that environmental regulation, the proportion of the primary industry, and agricultural financial support had a significantly positive, while environmental pollution and natural disasters a negative effect on the growth of GTFP, respectively. The average growth rate of agricultural GTFP in the three major basins is 3.3 %, and the agricultural green development situation is constantly improving, but the speed of improvement fluctuates significantly in the early stage, followed by amplitude reduction, showing an unbalanced profile among the regions. The Songhua River basin is mainly driven by the increase in technical efficiency, technological progress, and scale efficiency. The Yellow River basin and the Yangtze River basin are driven by technical efficiency and technological progress, respectively. The contribution of scale efficiency and factor allocation efficiency to the two is relatively weak. Therefore, we need to focus on the improvement of green total factor productivity, increase agricultural technological innovation, develop appropriate scale operation, improve regional coordinated development mechanism, and effectively implement environmental regulation policies [ABSTRACT FROM AUTHOR]

Under the new normal, digital economy as the core driver of economic development plays an important role in promoting the development of green economy. This article used the entropy method to measure the development level of digital economy from the two dimensions of digital industrialization and industrial digitalization. At the same time, the super-efficiency SBM model with constraints of land and energy elements was proposed to re-measure the efficiency of green economy. Based on China's provincial panel data from 2006 to 2019, this study empirically analyzed the impact of digital economy on the efficiency of green economy. The results showed that: 1 The regional digital economy gap in China was obvious, showing the spatial distribution characteristics of 'eastern region > central region > western region'. 2 Digital economy had significantly promoted the efficiency of green economy, and the conclusion was still robust after a series of tests. Dimensional regression showed that compared with industrial digitalization, digital industrialization had a greater effect on the efficiency of green economy. Subregional regression indicated that there was regional heterogeneity in the influence of digital economy on the efficiency of green economy, which significantly promoted the efficiency of green economy in the eastern and central regions, and the promotion effect on the eastern region was greater than that in the central region, but this effect in the western region did not pass the significance test. 3 Mechanism analysis showed that digital economy and digital industrialization indirectly improved the efficiency of green economy by optimizing the industrial structure, promoting technological innovation and deepening marketization, but industrial digitalization failed to improve the efficiency of green economy through industrial structure, technological innovation and marketization. 4 Threshold test showed that, constrained by the industrial structure, technological innovation and marketization, digital economy had a nonlinear influence on the efficiency of green economy, which changed after passing a certain threshold value and had obvious threshold feature. Therefore, the government should promote the coordinated development of digital economy with the characteristics of regional development to fully release the dividend of digital economy in the development of green economy, continue to promote the optimization and upgrading of the industrial structure, and promote technological progress to realize the development of green economy. In addition, differentiated market strategies should be formulated to promote the development of green economy in a more effective way. [ABSTRACT FROM AUTHOR]

In the context of achieving the 'dual carbon' goals of peaking carbon emissions and carbon neutrality, meeting emission reduction targets while ensuring stable economic growth is the economic development model China is seeking now. Therefore, exploring the mechanism of environmental regulation in China's economic growth, especially on technological progress, will help to analyze the mechanism of environmental policy on sustainable economic development. In this article, we used the SBM model to measure the green total factor productivity in the subdivided industries of the manufacturing industry in China from 2003 to 2018, and decomposed technological progress to examine the factor preference characteristics of biased technological progress, and finally used a panel regression model to empirically test the mechanism of environmental regulations on green total factor productivity and technological progress and their decomposition terms. The results showed that: 1 Green total factor productivity in China's manufacturing industry was generally increasing year by year, and technological progress was the main source of its growth. Environmental regulation showed an inverted U shaped relationship with green total factor productivity and technological progress, and the intensity of regulation was currently on the left side of the inflection point, and the increase in environmental regulation intensity helped to promote the growth of green total factor productivity and technological progress in China's manufacturing industry. 2 From the internal influence mechanism of technological progress, the results of biased technological progress factor preferences showed that the characteristics of input-biased technological progress factor preferences changed with the stage of economic development, and output-biased technological progress was more biased toward CO2 output, but it showed an improving trend year by year. The effects of environmental regulations on input-biased technological progress, output-biased technological progress, and scale technological progress were all significant, and the increase in the intensity of environmental regulations helped to enhance input-biased technological progress and reduce output-biased technological progress so as to save the input of production factors and reduce CO2 output. 3 The degree of opening to the outside world, capital intensity, and government subsidies all had positive effects on green total factor productivity and technological progress, and strengthening these factors could help to improve the economic development of the manufacturing industry. The study found that current technological progress had a certain 'carbon lock-in' effect on carbon emissions, and environmental regulations were not effective in reducing coal use. By measuring the current situation of China's manufacturing economy and the effect of environmental regulations, this study provides theoretical support for promoting China's green and high-quality economic development.

Sustainable (Green) development has been ever deepening the comprehensive transformation of the social economy at present. The green transformation of cultivated land use (GTCLU) has been one of the key steps towards the modern agriculture. The GTCLU has also been an effective solution to the ecological dilemma of cultivated land use, particularly on a positive response to national development strategies, such as green China and economic transformation. However, such a research is still lacking. In this study, an attempt was made to elucidate the concept of GTCLU, thereby to guide the subsequent activities of cultivated land use for the better improvement of green development. Moreover, the characteristics of GTCLU were also summarized from four aspects: the category of transformation, the causes of transformation, the manifestations of GTCLU, and the evolution form of GTCLU. A green evolution of cultivated land system was then proposed from the perspective of micro production factors, indicating a better starting point for the efficiency of GTCLU in China. As such, the index system of GTCLU was constructed scientifically. Thus, the panel data was collected from the 30 provinces in China from 2003 to 2017. A three-stage DEA-Malmquist and Tobit models were also utilized to calculate the efficiency and affecting factors of GTCLU. The results showed that: 1) The initial result of efficiency of GTCLU from the Malmquist model presented a V-shaped trend of “declining first, then increasing”. Specifically, the efficiency value was less than 1, indicating the green transition was invalid in most years. 2) The SFA regression was selected to remove the influence of environmental factors and random errors. After that, the efficiency value of GTCLU was 1.001, indicating an outstanding GTCLU degree. More importantly, the technological progress was greatly contributed to the efficiency improvement. Specifically, the change of technical efficiency, pure technical, and scale efficiency were the main bottlenecks for the efficiency improvement. 3) There were also the outstanding regional differences in the efficiency of GTCLU in China. The central region presented the best relative efficiency, followed by the northeast and eastern regions, and the western region was relatively the lowest. Meanwhile, there was a fluctuating upward trend in the time series, with an average annual growth rate of 0.84%. 4) The GTCLU efficiency was significantly depended on the agricultural economic level, cultivated land resource endowment, government support, and technology use intensity. A better GTCLU was then required the system, management innovation, as well as the promotion of resource endowment and technology. Specifically, four suggestions were addressed for each region during this time: 1) To take the sustainable development of cultivated land resource endowment; 2) To strictly control the low benefit mode of agricultural economic development; 3) To fully release the vitality of green cultivated land market and the driving force; 4) To continuously strengthen the green elements in the input and output of cultivated land use.

China's foreign direct investment (FDI) policy is an important part of the economic system; and to study the relationship between FDI policy and economic growth is not only the need of the FDI theory and economic growth research, but also the actual requirements of perfecting the FDI policy and ensuring the sustainable development of economy. On the one hand, China's FDI policy can influence the economic growth through such transmission mechanisms as capital accumulation, human capital development, technological progress and institutional change; it can also increase the domestic capital stock, improve human capital stock, promote technical advancement, increase production inputs, further economic scale expansion, raise the total factor productivity, promote the industrial structure adjustment, and improve the quality of economic growth. On the other hand, FDI policy ran aggravate environmental pollution degree, widen the gap between the regional economic development that will-restrict the sustainable development, threaten the national economic security through form dependence on FDI, influence the industry safety, and restrict the domestic enterprise development. We should hence improve the FDI environment, promote the enter threshold of the FDI-, enhance the guide function of FDI polity, to perfect the system of FDI management and other measures to promote the economic growth.

The theory of technological values or value-loaded technology has become the mainstream argument in the philosophy of technology. Engineers should not only consider the feasibility of technology but also bear the social responsibility for engineering/technology consequences. The conflict between engineering/technology progress and social development brings about some global problems, where the crisis arising from the traditional prospect the contemporary science and technology look forward is the root cause of the conflict. To assess the technological consequence is the necessary condition for the harmony between technology and society, and in this respect what the Russian scholars considered profoundly is to frame a new global prospect which will result in a holistic concept of technology, i. e. , a comprehensive view of technology involving the bearing capacity of nature, sustainable development of society and humanistic ideal.
