Environmental regulation and green technology innovation are important factors to achieve high-quality economic de-velopment.The influence relationship of the two factors is a hot issue in academic circles.The existing literature focuses on the impact of environmental regulation on the overall green technology innovation.This paper further subdivided the overall green technology innovation,constructed a mathematical model,deduced the impact mechanism of environmental regulation on hetero-geneous green technology innovation,and employed the panel data collected from 30 provincial-level regions in China from 2010 to 2019 to establish static and dynamic panel regression models for empirical testing.The empirical research drew several conclu-sions.Firstly,with the improvement of environmental regulations,the trend of overall green technology innovation and clean pro-duction technology innovation decrease first and then increase,indicating a U-shaped relationship between the both types of technology innovation and environmental regulations.Secondly,the level of environmental regulation has a positive impact on pollution control technology innovation.Thirdly,in terms of controlling variables,enterprise size promotes overall green technolo-gy innovation;the ownership structure promotes clean production technology innovation,but it is not conducive to pollution con-trol technology innovation;the degree of trade openness has a promoting effect on the innovation of pollution control technology;the effect of R&D on different types of green technology innovation varies.Based on the research findings,some policy recom-mendations are proposed to promote green technology innovation in terms of environmental regulatory intensity,environmental reg-ulatory measures,enterprise scale and trade openness.
