Exploring the impact of different environmental regulatory tools on technological innovation and path selection of enterprises is of great significance for China. Based on the panel data of industrial enterprises above the designated scale in 30 provinces from 2013 to 2017, this study divided technological innovation into internal independent R&D and external introduction, and used fixed effect regression to examine the impact of different environmental regulatory tools on technological innovation of industrial enterprises. The results show that: The two types of environmental regulatory tools have played different roles in promoting the expenditure on R&D, and showed a trend of change over time, which partly verifies the “weak” version of porter’s hypothesis. From 2013 to 2015, command-and-control tools did not play a significant role in promoting the R&D expenditure, but they did play a significant role in promoting the R&D expenditure under the impetus of a new round of “environmental protection storm” in 2016 to 2017. Since 2013, market incentives had significantly promoted the internal expenditure, external introduction, and total expenditure on R&D, and the impact showed a decreasing trend. Meanwhile, their promoting effect on the internal expenditure on R&D was greater than that on the external expenditure. Carbon trading market had played a promoting role in the R&D of industrial enterprises, which is mainly reflected in the external introduction. Spatially, the results of the eastern and central regions are relatively consistent and robust with the results of the whole country. The results in western China are consistent with the “narrow” version of porter’s hypothesis. It was found that market-driven environmental policy tools had more innovative incentives for industrial enterprises in western China than command-and-control environmental regulations. This study innovatively introduces renewable energy generation subsidies and carbon trading market into the environmental regulation. In refining the mechanism of Porter hypothesis, it provides a scientific basis for the state to further optimize the environmental policy system in order to stimulate the technological innovation of industrial enterprises.
