Abstract:This paper selects the data of 31 provinces of China from 2005 to 2015, studies the impact of 3 environmental regulation tools on technological innovation of the 31 provinces and the east, middle and western regions by using the panel data model. The results show that, the command-controlled environmental regulation tools have no significant impact on the performance of technological innovation, and the market-motivated environmental regulatory tools have a significant incentive effect on technological innovation, the environmental regulation tools of public participation have obvious inhibitory effect on technological innovation. The output of technology innovation in various regions reflects the regional differences of the performance of environmental regulation tools in China. In addition, the explanatory variables with lagged first stage are used as explanatory variables, and generalized moment estimation (GMM) method is used to analyze the dynamic panel data model.
