Study On The Influence Of Double Environmental Regulation On Green Total Factor Productivity

Since reforming and opening,our country economy begins to develop rapidly.In1978,China’s GDP was only 364.5 billion yuan.In 2022,it reached 121 trillion yuan,a difference of more than 330 times.However,at present,the economic situation our country is facing is increasingly complex and volatile.The traditional resource-intionoriented economic development method has caused inestimable loss and damage to environment,and other problems such as environmental pollution,resources depletion and industrial backwardness are also further urgent for our country to adopt the path of economic sustainable development as soon as possible.Green total factor productivity(GTFP)is an important index to measure healthy and green economic development.Improving GTFP is a good way to balance environmental protection and economic development.As an important means of environmental protection,environmental regulation has an inseparable relationship with the promotion of GTFP.At the same time,with the improvement of people’s economic life and living standards,more and more people have realized that a good living environment is also their own precious wealth.The power of informal environmental regulation has gradually grown and played an increasingly obvious role.Therefore,this paper will discuss the impact of dual environmental regulations including formal and informal environmental regulations on GTFP,in order to put forward more reasonable and effective suggestions to further promote the promotion of GTFP.In this paper,30 provinces,municipalities and autonomous regions were taken as research objects(except Tibet),and the influence of dual environmental regulations on GTFP was discussed by the combination of qualitative and quantitative methods.Firstly,the SBM-GML index method was used to estimate and analyze the variation of GTFP and its decomposition in each region.Then,a model is constructed to discuss the influence of formal and informal environmental regulations on GTFP and the relationship between informal and formal environmental regulations,which include two types of environmental regulations: command-control and market-incentive.The empirical results show that the overall GTFP increased gradually from 2011 to 2020,slowly from 2011 to 2014,and accelerated from 2014 to 2020,with an annual average of 1.83,which is improved to some extent.The green total factor productivity growth rate(GML)index has been greater than 1 for ten years,which is mainly driven by technological progress,and there is still room for further improvement of technological progress efficiency.According to the regression results,the influence of formal environmental regulations,including command-control and market-incentive environmental regulations,on GTFP presents an inverted U-shaped relationship,that is,formal environmental regulations with a certain intensity are conducive to the improvement of GTFP,but after a certain limit,GTFP will decline with the increase of formal environmental regulation intensity.Informal environmental regulation can be used as a supplement to formal environmental regulation and promote the improvement of GTFP to a certain extent.The regression coefficient of the interaction term between formal and informal environmental regulations is positive,and there is a complementary relationship between the two.Informal environmental regulations can strengthen the role of formal environmental regulations on GTFP.According to the research conclusion,the following suggestions are put forward in this paper: strengthen the level of technological innovation and development to promote technological progress,optimize the allocation of resources to promote the efficiency of technological progress;Diversify and innovate formal environmental regulation methods,explore the optimal range of formal regulation intensity,and avoid the "overcorrection" situation;Guide and encourage non-governmental environmental organizations and groups to strengthen informal environmental regulation groups and regulate and guide them to more effectively protect the environment;Promote the effective combination of formal and informal environmental regulations,give full play to their respective advantages,jointly promote environmental protection and highquality economic development,gradually establish a sound environmental regulation mechanism,and promote a good balance between environmental protection and economic development.
