Research On The Impact Of Environmental Protection Tax On Industrial Green Total Factor Productivity

Over the past 40 years of reform and opening up,China has made major breakthroughs in economy,science and technology,and culture.In the process of rapid economic development,however,the conflict between economic growth and environmental pollution has become increasingly prominent.With the increasing emphasis on ecology in China,it has increased its efforts to protect the environment and its environmental protection policies have become more and more perfect and strict.2018 saw the official start of China’s environmental protection tax,which is not only a perfection of the sewage charge system,but can also further facilitate the internalisation of external costs in industrial companies that pollute heavily,pushing industrial enterprises to green transformation and upgrading,and reducing the environmental.In this context,this paper is based on the 2010 National Environmental Law.In this context,based on the industrial data of 30 provinces in China from 2010 to 2020,this paper analyzes the impact of environmental protection taxes on industrial green total factor productivity and the mesomeric effect generated by the intermediary transmission mechanism of different technological progress paths,with a view to providing feasible suggestions for achieving a win-win situation of industrial green transformation and environmental protection.In terms of theory,this thesis explains the concepts of green total factor productivity and environmental protection tax,and the mechanisms of influence between environmental protection taxes,technological progress and industrial green total factor productivity are analyzed in detail.,using externality theory,Coase’s theorem,Porter’s hypothesis and green sustainable development theory as the theoretical support.On the empirical side,this paper calculates the industrial green total factor productivity of 30 provinces in China through the SBM-GML index model,then uses the fixed effect model to study the impact of environmental protection taxes on industrial green total factor productivity,and finally uses the mesomeric effect model to study the mesomeric effect of different technological progress paths.The study finds that: firstly,national industrial green total factor productivity has been rising year on year,with the highest growth rate in the east,followed by the central and the lowest in the west.;secondly,the environmental protection tax can significantly promote the national industrial GTFP,but the environmental protection tax only has a significant positive effect on green total factor productivity of industrial companies in the east,but not in the central and western regions,but not in the central and western regions;thirdly,the environmental protection tax promotes the industrial GTFP through independent innovation and the introduction of overseas technology.Third,the environmental protection tax promotes GTFP through independent innovation and the introduction of foreign technology,but not through the introduction of domestic technology.Based on the above findings,countermeasures to enhance industrial green total factor productivity are proposed at the government and enterprise levels respectively: the government should further improve China’s current environmental protection tax policy,plan environmental protection tax revenues rationally,encourage enterprises to carry out independent innovation and technology introduction,carry out evaluation and adjustment of environmental protection tax policy,improve the collection and administration mechanism of environmental protection tax,and strengthen industrial enterprises’ tax compliance;enterprises should establish the concept of ESG governance,actively assume environmental responsibility,attach importance to independent innovation and technology introduction,and promote industrial enterprises’ green transformation.
