Abstract：By taking China’s three major regions,30 provinces’panel data from 2004 to 2013 as samples, and using nonparametric DEA-Malmquist index to divide technical progress into scientific and technological progress,the pure technical efficiency change and scale efficiency change,the paper using panel data measure-ment methods analyzes the influence of technical progress and its decomposition part on energy efficiency.The results show that,from a national point of view,technical progress has had a significant positive impact on the improvement of energy efficiency.Among them,the scientific and technological progress and the pure technical efficiency have significant contribution on energy efficiency,and scale efficiency in the short term has a slight negative impact on energy efficiency.In the three regions,technical progress’s influence on energy efficiency of central part is the largest,which is followed by eastern China.The influence of west is negative.Technical progress in western China not only fails to make a useful contribution to the improvement of energy efficiency, but hinders the improvement of energy efficiency.
