Abstract

This study quantitatively evaluates the coordination level between pollution reduction and carbon reduction in 30 provincial-level regions in China from 2006 to 2020. It analyzes the spatiotemporal evolution trend of this coordination level using the Dagum Gini coefficient and spatial Markov chain. Additionally, it empirically tests the impact of green technology innovation on the coordination level between pollution reduction and carbon reduction. The research findings are as follows: 1) The overall trend of the coordination level between pollution reduction and carbon reduction in China is increasing, exhibiting a "club convergence" phenomenon. The spatial difference of the coordination level between pollution reduction and carbon reduction shows a downward trend in China and three major regions. 2) Green technology innovation plays a significant role in enhancing the coordination level between pollution reduction and carbon reduction, while environmental regulation and government financial support significantly enhance its promoting role. 3) Energy consumption intensity reveals the mechanism of green technology innovation affecting the coordination level between pollution reduction and carbon reduction, environmental regulation and government financial support play negative and positive regulatory roles on this impact mechanism, respectively. 4) Heterogeneity analysis reveals that green technology innovation has a significant promoting role in the coordination level between pollution-carbon reduction for central and western regions, but not for eastern region.

Key words： green technology innovation; pollution-carbon reduction; environmental regulation; financial support; energy consumption intensity; driving mechanism
