我国能源效率的地区差异及影响因素——基于异质性随机前沿边界模型的实证分析

Regional Difference and the Impacting Factors of Energy Efficiency in China

在异质性随机边界模型的分析框架下,基于我国大陆27个省、市、自治区1985—2012年的面板数据,对各省份能源利用的技术效率进行测算,并对能源效率地区差异、影响因素进行分析。结果表明:我国的能源利用的技术效率整体水平不高,效率损失约为30%,但随着时间的推移呈现出技术效率逐渐上升的趋势;技术效率区域差距明显,东部区域最高,中部和西部区域的技术效率水平相近。制定差异化产业结构、能源结构、产权结构和对外开放等目标,有利于技术效率水平的提高和缩小地区间的效率差距。

Within the framework of heterogeneous random boundary models, this paper made an empirical study using the 1985 to 2012 panel data from the 27 provinces and regions to work out the technical efficiency of energy use of the regions, as well as the energy efficiency of regional differences and the influence factors. The results show that the technical efficiency of energy use in China is not high in general with a 30%efficiency loss, but rising gradually with the time. It varies considerably with region, with the eastern region having the best performance, and the central and western regions similar to each other. Differentiated goals in industrial structure, energy structure, property right structure and opening to the public is conducive to use the technical efficiency better and reduce the gap in efficiency between the regions.
