Abstract：Incorporating undesirable output in the input-output indicators, the total-factor energy efficiency (TFEE) of 29 Chinese administrative regions during 2003~2012 was computed based on super-efficiency DEA. Then the TFEE of western region was decomposed with Malmquist index and determinants of energy efficiency were examined with Tobit model. Results indicated that energy efficiency of western region was far below that of eastern region, and also below that of central region, which reflected the low level of energy efficiency of western region. TFEE varied among western provinces, but the gap was narrowed in recent years. TFEE of western region showed a decending tendency during research period. TFEE was influenced significantly by technical change, pure technical efficiency change and scale efficiency change, and technology degradation was the most significant factor that led to the decline of TFEE of western region. Industrial structure upgrade and technology progress had positive effects on energy efficiency, while energy price and coal consumption had negative effects on energy efficiency.
