异质性视角下我国全要素能源效率研究

Study on China's Total Factor Energy Efficiency in the Perspective of Heterogeneity

以考虑区域异质性的Meta-frontier SBM模型可测算1998—2014年我国30个省市区(未包括西藏及港澳台)的共同前沿能源效率和区域前沿能源效率,并对能源利用无效率的来源从技术差距无效率和管理无效率两个方面分析。在能源利用效率方面,我国东中西三大地区的能源效率存在一定差异,但都呈现先上升后下降再上升的趋势;在能源利用技术方面,东部地区拥有能源利用的前沿技术,中西部地区的能源利用技术与前沿技术的差距比较明显,同时中西部地区的能源利用技术之间的差距逐渐缩小;在能源利用无效率原因方面,东部地区主要由管理无效率造成,中部地区主要来源于技术差距无效率,西部地区技术差距无效率和管理无效率所占的比重都比较大。

Using the meta-frontier SBM model considering regional heterogeneity,the author measures the energyefficiency in meta-frontier and group frontier of China’s30provinces from1998to2014and analyzes the energy inefficiencyfrom the aspects of technology gap inefficiency and managerial inefficiency.It is found that:in terms of energy efficiency,theenergy efficiency in three regions is not the same,and all of them shows the trend of rising first,falling then,and rising again;interms of energy technology,the eastern region is in the frontier,the central and western regions lag behind,while the gap isnarrowing;in terms of cause for energy inefficiency,causes for that in eastern region is managerial inefficiency,causes for thatin central region is technology gap inefficiency,and causes for that in western region is both the managerial inefficiency andtechnology gap inefficiency.
