环境规制强度对中国工业全要素能源效率的影响——基于2003—2016年30省域面板数据的实证研究

An Empirical Study of Environmental Regulation Impact on China’s Industrial Total Factor Energy Efficiency:Based on the Data of 30 Provinces from 2003 to 2016

环境污染促使了环境规制的产生,环境污染又与能源消耗之间具有密切的相关性,文章主要研究环境规制是如何影响中国工业全要素能源效率的。基于中国省级面板数据,利用超效率SBM模型对中国各地区工业全要素能源效率进行测算,然后采用静态面板估计和SYS-GMM动态面板估计方法进行实证检验。研究结果显示,中国工业全要素能源效率整体比较低。环境规制与工业全要素能源效率之间存在一种"U"型关系,较弱的环境规制强度不利于工业全要素能源效率的提高,但当环境规制强度增加到一定程度即跨过"拐点"后,能够促进工业全要素能源效率的提高。

Environmental pollution has contributed to the emergence of environmental regulation and there is a close correlation between environmental pollution and energy consumption. This paper mainly explores how environmental regulation affects industrial total factor energy efficiency in China. Based on the provincial panel data of China,the industrial total factor energy efficiency in various regions of China is calculated by using super-efficient SBM model,then the static panel estimation and SYS-GMM dynamic panel estimation methods are applied for further empirical tests. The results show that the overall industrial total factor energy efficiency is relatively low in China. There is a U-shaped relationship between the environmental regulation and industrial total factor energy efficiency. The weak environmental regulation is not conducive to the improvement of the industrial total factor energy efficiency. However,when the intensity of environmental regulation increases to a certain extent or,in other words,crosses the inflection point,the industrial total factor energy efficiency can be promoted.
