An Empirical Study On The Impact Of Environmental Protection Tax On Enterprise Ereen Technology Innovation Efficiency In China

This paper makes enterprise with environmental protection tax and enterprise efficiency of green technology innovation as the research content,from two aspects of theory and practice to study the effect of the two relations.In terms of theories analysis,in the first place,the theories of environmental protection tax and innovation efficiency of enterprises’ green innovation should be sorted out.Furthermore,the mechanism of action is researched from the two sides of "promoting effect" and "suppression effect".In the empirical analysis,based on the empirical evidence of listed companies in Shanghai and Shenzhen a-share highpollution industries from 2013 to 2018,the DEA method is adopted to get the efficiency of listed companies with high pollution.Secondly,construct Tobit regression model by taking DEA measure of green technology innovation efficiency as explained variable,environmental taxes as explanatory variables,and by joining a series of control variable Tobit regression model,in order to study the effect of environment tax of enterprise green technological innovation.it is concluded that environment tax will effectively promote the enterprise green technology innovation efficiency;Thirdly,the regression coefficients of control variables are analyzed to see if enterprise size,enterprise growth,cash holdings,product prospects have a significant impact on the efficiency of technological innovation;Finally,through heterogeneity analysis,it is found that environmental tax has heterogeneity in promoting efficiency of green technology innovation.According to the research conclusion,specific suggestions are put forward from the perspective of the government,enterprises and the public to stimulate the "promoting effect" of environmental protection tax on the innovation efficiency of green technology.According to the research conclusion,this paper proposes specific sugge stions from the perspectives of the government,enterprises and the public tostimulate the "promoting effect" of environmental protection tax on the inn ovation efficiency of green technology.It is expected to provide theoretical support for the government to adjust and optimize the environmental protect ion tax policy to force enterprises to carry out green technology innovation,and guide enterprises to better cope with the opportunities and challenges br ought by environmental tax,so as to make the best choice to promote envir onmental governance and enterprise green technology innovation.
