Environmental regulation is an important factor influencing green technological innovation. The thesis analyzes the impact mechanism of environmental regulation on green technological innovation by constructing a theoretical model. On this basis, select panel data of 30 provinces and cities in China from 2005 to 2020, establish a panel threshold model, and conduct an empirical test on the mechanism of environmental regulations affecting green technology innovation. The results show that: (1) By exploring the mechanism of environmental regulation affecting green technological innovation, it can be known that environmental regulation will have an impact on green technological innovation; (2) The impact of environmental regulation on green technological innovation is not a simple linear relationship, but a significant The characteristic of the V-shaped threshold is that the intensity of environmental regulations at different stages has different relative strengths to the “following cost effect” and “reverse effect” of green technological innovation. When the environmental regulation is greater than 0.4019, the environmental regulation has a positive effect on the efficiency of green innovation. The driving effect began to appear. That is, as environmental regulations become more and more stringent, its role in green innovation has changed from negative to positive; (3)The conditions of transportation facilities, labor investment, and capital investment have significantly promoted green technological innovation, while the degree of openness to foreign trade has significantly inhibited Green technology innovation.
