环境规制强度影响能源效率的门槛效应研究——基于PSTR模型

利用非径向-SBM和CCR模型测算了我国30个省市(暂不包括西藏和港澳台地区)2007-2016年间的环境规制强度以及能源效率,构建面板平滑转移回归模型(PSTR),分析了环境规制强度对我国能源效率的连续非线性变化的影响.研究结果显示,全国环境规制强度对我国能源效率存在非线性效应,二者之间呈倒“U”型关系.环境规制强度小于门槛值0.6376时,环境规制对能源效率产生创新补偿效应,当环境规制强度高于门槛值0.6376时,环境规制对能源效率产生遵循成本效应.而我国东西部地区的环境规制强度与地区能源效率间却存在着与之相反的“U”型效应.

Threshold Effect of Environmental Regulation Intensity on Energy Efficiency: Based on PSTR Model

The non-radial-SBM and CCR models were used to measure the environmental regulation intensity and energy efficiency of 30 provinces (excluding Tibet, Hong Kong, Macao, and Taiwan) and municipalities in China from 2007 to 2016. A panel smoothing transfer regression model (PSTR) was constructed to analyze the impact of environmental regulation intensity on the continuous non-linear change of energy efficiency in China. The results show that the national environmental regulation intensity has a non-linear effect on China''s energy efficiency, and there is an inverted "U" relationship between the two. When the intensity of environmental regulation is less than the threshold value 0.6376, environmental regulation has an innovative compensation effect on energy efficiency. When the intensity of environmental regulation is higher than the threshold value 0.6376, environmental regulation has a cost effect on energy efficiency. However, there is an opposite "U" effect between the intensity of environmental regulation and regional energy efficiency in the eastern and western regions of China.
