环境规制是否促进我国城市的绿色经济增长?

Does Environmental Regulation Promote Green Economic Growth of Chinese Cities?

本文采用基于非径向方向距离函数的全域Luenberger生产率指标,将环境污染与经济增长纳入同一框架测算我国城市绿色经济增长率,在此基础上考察环境规制对绿色经济增长的影响及其机制。针对地区发展不均衡问题,本文以人均地区生产总值(GDP)作为约束条件,综合运用交互项回归模型、面板门槛回归模型和部分线性函数系数面板模型,探究环境规制对我国城市绿色经济增长的异质性影响。研究结果表明:环境规制显著推动城市绿色经济增长,其驱动力源自技术效率的改善和技术水平的提升。当城市人均GDP高于2.28万元(2004年价格水平)时,环境规制对绿色经济增长的正向影响才开始显著,且该效应随着人均GDP水平提高而增大。本研究为考察环境规制与城市绿色发展的关系提供新的经验证据。

This paper examines the effect of environmental regulation on green economic growth and its underlying mechanisms.Using the global Luenberger production index based on non-radial direction distance function,we build a comprehensive framework incorporating pollution and economic growth to measure Chinese city green economic growth rate.In face of regional imbalance,we exploit interaction term,threshold panel and partially linear functional coeficient models subject to income per capita to reveal heterogeneous effects of environmental regulation on the green economic growth of Chinese cities.The results show that environmental regulation significantly promotes urban green economic growth,mainly through the improvement of technology efficiency and technological level.The promoting impact is not significant until urban income per capita reaches 22.8 thousand yuan(at the 2004 price level),and continuously increases after hitting the critical point.This article provides fresh evidence for investigating the relationship between environmental regulation and urban green economic growth.
