Research of Regional Energy Efficiency Based on Undesirable Outputs and Its Influential Factors: A Case of Western China

AbstractUnder the frame of Total-Factor Energy Efficiency, considering desirable outputs and undesirable outputs taking by energy and related factors, this paper uses super efficiency DEA method to measure energy efficiency of 11 provinces (autonomous regions, municipalities) in western China from 1989 to 2009, and utilizes fixed effect model of variable intercept to analysis factors of influencing energy efficiency of provinces (autonomous regions, municipalities) in western China. The analysis shows that: (1) Under the situation of overall low energy efficiency in western China, in region, energy efficiency level presents the slow rise tendency from the year of 2005 after maintaining certain time interval slow drop. In the region the difference is small. (2) Factors of technical progress, industrial structure, government influence, opening degree, system variable as well as structure of energy consumption have different effects on energy efficiency, and these factors to action mechanism of energy efficiency exist difference
