摘　　要：基于2013—2020年中原城市群30个地级及以上城市的面板数据,采用SBM-Malmquist-Luenberger指数测度了绿色全要素生产率,结果显示:中原城市群绿色全要素生产率平均增长率为8%,城市间绿色全要素生产率水平存在差异。进一步实证分析了数字经济视角下环境规制对绿色全要素生产率的影响,得出研究结论:环境规制与绿色全要素生产率是非线性关系且呈现“U”型特征,多种方式的稳健性检验显示该结论仍然成立;中介效应结果显示数字经济、技术进步和技术效率是环境规制影响绿色全要素生产率的重要渠道,发挥正向中介作用;异质性检验结果显示不同区域环境规制对于绿色全要素生产率的影响存在差异。Based on the panel data of 30 cities in the Central Henan urban agglomeration from 2013 to 2020,this paper measures GTFP by using the SBM-Malmquist-Luenberger index.The results shows that the average growth rate of green total factor productivity in central plains urban agglomeration is 8%,and there are differences in green total factor productivity among cities.This paper further empirically analyzes the impact of environmental regulation on green total factor productivity from the perspective of digital economy,and draws the conclusion that the relationship between environmental regulation and green total factor productivity is nonlinear and presents a“U”shape.The robustness tests of various methods show that the conclusion is still valid.The results show that digital economy,technological progress and technological efficiency are important channels for environmental regulation to affect green total factor productivity,and play a positive mediating role.Heterogeneity test results show that environmental regulations in different regions have different impacts on green total factor productivity.
