Since the reform and opening up,with the rapid development of China’s economy,environmental problems have become a major problem of quality development in China at present.Environmental regulation,as a kind of social regulation,is an inevitable choice for China to relieve environmental pressure and improve environmental quality.However,China’s environmental regulation is characterized by the volatility of dynamic governance.The fluctuation of environmental regulation results in the low efficiency of environmental governance in China.Therefore,it is of great significance to study the influence direction and action mechanism of environmental regulation volatility on China’s environmental governance performance and find the optimal range of environmental regulation volatility in China,so as to improve China’s environmental quality and alleviate the realistic contradiction between economic development and environmental pollution.This paper first introduces relevant concepts and hypotheses on environmental governance.Based on these concepts and hypotheses,it conducts mechanism analysis on factors that may affect environmental governance performance,laying a theoretical foundation for setting up empirical models.Secondly,this paper analyzes and comprehensively analyzes the current situation of environmental pollution,environmental governance performance and environmental regulation fluctuation in China,summarizes the relevant problems China is facing at present,and concludes the realistic features that environmental regulation fluctuation may lead to the decline of environmental governance performance.Then,relevant measurement models were constructed for the provincial panel data of 30 provinces and municipalities in China.First,descriptive statistics was conducted for the data,and then fixed model effect was applied to analyze the dynamic panel data through Hausman test.The fixed effect model and systematic GMM were used to analyze the provincial panel data.After that,China’s 30 provinces and autonomous regions were divided into eastern coastal regions,central inland regions and western outlying regions for regional discrimination.Finally,the empirical results obtained by the test of robustness.Based on the analysis of the theoretical mechanism and the results of the empirical test,the conclusion of this paper is obtained and the corresponding policy recommendations are given.The research results show that China’s environmental regulation volatility has a negative impact on China’s environmental governance performance,that is,environmental regulation volatility is not conducive to the mitigation of environmental pollution.In addition,there is a "positive U”curve relationship between environmental control fluctuation and environmental pollution in China,that is,there is an "optimal interval" for environmental control.As long as the intensity of environmental control is within the "optimal interval",China’s environmental pollution can be at a lower level.If the fluctuation range of environmental control is beyond the range of "optimal range",it is not conducive to the improvement of China’s environmental quality.According to the regression results of other control variables,the rapid economic development,the continuous promotion of urbanization and the continuous expansion of industrial production scale will be the main factors causing environmental pollution in China in the future.Adhering to reform and opening up,accelerating industrial structure and economic transformation,and optimizing investment efficiency and structure are the top priorities for China to successfully fight the "blue sky fight" in the future.From a regional perspective,the main causes of environmental pollution in different regions of China are different from each other and the focus of environmental governance is different.The phenomenon of "pollution paradise" in the central inland region caused by foreign trade makes the environmental deterioration more obvious.The western outlying areas are limited by the production efficiency and technological level,and the economic development is relatively rough,which leads to serious environmental pollution.In view of the above three aspects of the main conclusions,this paper respectively from the rationality and stability of control intensity,the possibility of economic and environmental coordination and the necessity of formulating environmental protection regional policies.Different from previous studies,the innovation of this paper mainly focuses on the following three aspects.Secondly,it selects the data of the decade from 2007 to 2016 to construct the panel data to guarantee the timeliness of the data and the robustness of the estimated results.Thirdly,the method of combining static and dynamic panel data should be used to comprehensively consider the regional heterogeneity of panel data,and the estimation results of panel data should be systematically analyzed to ensure the comprehensiveness of the conclusions and the scientific nature of policy recommendations. |
