Abstract: Environmental regulation and green technology innovation are not only the specific manifestations of practicing the new development concept,but also an important path to promote the high-quality development of industry.Firstly,this paper uses EBM-ML index method to calculate the industrial green total factor productivity,and then uses mathematical statistical model to verify the effect of different types of environmental regulation tools on industrial green development and the intermediary effect of green technology innovation.The results show that the green total factor productivity of Chinas industry shows a growth trend during the investigation period,and its main growth source is the outward movement of the frontier of industrial production;the effect of public participation environmental regulation tools on industrial green development is first promoted and then restrained,while administrative orders and market incentive environmental regulation tools inhibit industrial green development;this conclusion is still valid after a series of robustness tests and considering endogenous problems.Further research shows that green technology innovation has a significant intermediary effect in the transmission path of environmental regulation affecting industrial green development,but for different types of regulation tools,the intermediary effect is slightly different.
