【 摘 要 】

This paper measures energy efficiency of 30 regions in China during 2010-2014 by using the three-stage data envelopment analysis (DEA) model. The results indict that environmental factors and random error both have significant impacts on energy efficiency. After eliminating these influences, the results present that the energy efficiency in developed regions is almost higher than that in undeveloped or resource-rich regions and low scale technical efficiency is the main constraining factor in inefficient regions. Based on the efficiency characteristics, this paper divides all regions into four types and provide differential energy strategies.
