CONVERGENCE ANALYSIS OF ENVIRONMENTAL EFFICIENCY FROM THE PERSPECTIVE OF ENVIRONMENTAL REGULATION: EVIDENCE FROM CHINA
使用固定效应和门槛回归模型，分析环境规制对中国区域环境效率收敛的影响，发现环境效率存在收敛趋势，且规制效果先抑制后促进。
The aim of this paper is to analyze the impact of environmental regulation on regional environmental efficiency convergence using the fixed effects model and threshold regression model. The results show that the differences in environmental efficiency have a convergence trend in China, as well as in the eastern, central and western regions. The effect of environmental regulation on regional environmental efficiency is inhibition first and then promotion, research and development investment and outward foreign direct investment have a positive transmission effect; when environmental regulation intensity exceeds a certain threshold, the growth rate of environmental efficiency in the central and western regions will be significantly higher than that in the eastern regions.
