Environmental Regulations, Green Technology Innovation, and High-Quality Economic Development in China: Application of Mediation and Threshold Effects

In this article, we consider sample data from 30 regions in China 2004 to 2020. We use the entropy method measure high-quality development level, then examine intermediary and threshold effects verify main paths by which green technology innovation mediates relationship between environmental regulation intensity quality of economic development. Our conclusions are as follows: (1) There is a “U”-shaped When low, there negative (inhibitory) two, while positive (promoting) when high. Furthermore, high proportion secondary industries inhibit development, perfect infrastructure information access can promote excessive population density hinders (2) also exists innovation, forms co-directional change relationship. Green has significant mediating effect on impact (3) The test confirms existence double thresholds. level not high, regulations However, reaches certain will This paper theoretical reference for achieving goals; thus, our results expected provide support China’s
