Research On The Impact Of Environmental Regulation On Green Total Factor Productivity In China

Since the reform and opening up in 1978,China’s economy has developed rapidly and achieved remarkable results,but the cost of resources and environment is also quite high.Problems such as resource shortage and environmental pollution are obvious,which directly involve people’s livelihood issues and future sustainable development plans."Economic growth-environmental pollution-pollution control" is a route that developed countries such as Europe and the United States have long explored China has learned from the experience of developed countries and established an environmental regulation system,which has played an important role in practice.In this context,this paper studies the impact of China’s current environmental regulation system on green total factor productivity.In this paper,we first sort out and review the relevant research literature and theories at home and abroad,and analyze the mechanism of environmental regulation on green total factor productivity.Secondly,the SBM-GML index model was used to measure the green total factor productivity of various regions in China and analyzed it in different dimensions.Based on the innovation perspective of regional pollution heterogeneity,the stepwise regression test method,the mediation effect model combined with the mixed effect model,and the nonparametric percentage Bootstrap method are used to study the direct and indirect effects of the environmental regulation system on China’s green total factor productivity.On this basis,the generalized least squares model is further used to study the time-lag effect of environmental regulation on green total factor productivity.Conclusions:(1)China’s green total factor productivity has risen steadily,among which regional differences and individual differences are significant.(2)On the whole,the direct effect of environmental regulation on green total factor productivity is negative.However,its indirect effect is valid and the nature is a masking effect,and the "Porter hypothesis" is established in China.(3)Environmental regulation in lightly polluted areas can have a significantly positive indirect effect on green total factor productivity through technological innovation,and the direct effect of three environmental regulations in heavily polluted areas on green total factor productivity is positive,with slightly different indirect effects.(4)Except for public-type regulation in lightly polluted areas and command-type regulation in heavily polluted areas,other environmental regulations have significant time-lag effects on green total factor productivity.Finally,based on the conclusions and existing problems,relevant optimization suggestions such as actively developing green total factor productivity,rationally formulating the intensity of environmental regulation policies,improving the implementation efficiency of environmental regulation policies and strengthening regional linkage,and promoting technological innovation are put forward.
