资源型城市环境规制的绿色发展效应及其门槛特征——基于内蒙古地级市的实证检验

Green development effect and threshold characteristics of environmental regulation in resource based cities——Empirical test based on prefecture level cities in Inner Mongolia

基于2004-2016年内蒙古自治区9个地级市面板数据,运用PSTR模型实证检验环境规制的绿色发展效应及其门槛特征。结果发现,内蒙古自治区环境规制对绿色发展具有非线性影响及门槛效应,以门槛值为拐点,分别呈递减和递增的变化趋势,并且环境规制对绿色发展的影响地区差异显著。此外还发现,人力资本对内蒙古绿色发展水平的提升具有促进作用。因此,一方面要因地而异制定程度适宜的差异化环境规制政策;另一方面,要扩大教育、培训投入以提升人力资本水平,使得环境规制与人力资本协同发展,共同提升内蒙古绿色发展水平。

Based on the panel data of nine prefecture level cities in Inner Mongolia Autonomous Region from2004 to 2016, PSTR model is used to empirically test the green development effect and threshold characteristics of environmental regulation. The results show that environmental regulation has a non-linear effect and threshold effect on green development in Inner Mongolia Autonomous Region, with the threshold value as the inflection point, showing a decreasing and increasing trend respectively, and the impact of environmental regulation on green development has significant regional differences. In addition, it is found that human capital can promote the level of green development in Inner Mongolia. Therefore, on the one hand, it is necessary to formulate differentiated environmental regulation policies with appropriate degree according to different places;on the other hand, it is necessary to expand investment in education and training to improve the level of human capital, so as to make environmental regulation and human capital develop in coordination and jointly improve the level of green development in Inner Mongolia.
