通过搜集中国2000～2014年数据,运用DEA Malmquist指数测算中国30个省域全要素能源效率,并进一步分解求得技术水平、纯技术效率和规模效率为验证环境规制与全要素能源效率间波特假说是否存在,分别运用环境规制对规模效率、纯技术效率、技术水平和全要素能源效率进行面板门限回归结果表明:技术水平退步是我国全要素能源效率下降的主要原因.环境规制对规模效率的影响为负,波特假说不成立.环境规制与纯技术效率存在单门限效应,且环境规制在不同区间对纯技术效率的影响均为正,波特假说始终成立.环境规制与全要素能源效率和技术水平均存在单门限效应,当环境规制强度低于0.0002时,环境规制对全要素能源效率和技术水平的影响为正,此时波特假说成立;而当环境规制强度超过0.0002时,环境规制对全要素能源效率和技术水平影响为负,此时波特假说不成立.因此,政府制定环境规制政策需要考虑到环境规制强度对规模效率、纯技术效率和技术水平效果的差异.%The total factor energy efficiency of China's 30provincial administrative regions during 2000～2014was estimated based on DEA-Malmquist index.Then the total factor energy efficiency was decomposed into technical level,pure technical efficiency and scale efficiency.To testify the Potter hypothesis,the panel threshold regression model was adopted to simulate the environmental regulation on total factor energy efficiency,technical level,scale efficiency and pure technical efficiency.Results showed that technical level regression constituted a major cause for the decline of total factor energy efficiency in China.Environmental regulation exerted a negative influence on the scale efficiency,indicating Potter hypothesis as invalid.Single threshold existed between environmental regulation and pure technical efficiency,and there was a positive impact at different intervals,revealing the existence of Porter hypothesis.The impact of environmental regulation on total factor energy efficiency and technical level was positive when the environmental regulation was less than 0.0002,and the Porter hypothesis was correspondingly valid.Otherwise,it didn't stand.Therefore,government should formulate environmental regulation policy after considering varied effect on technical level,pure technical efficiency and scale efficiency.
