Abstract
Based on the combination of non-parametric Data Envelopment Analysis (DEA) with the Malmquist Productivity Index (MPI) under the framework of total factor, we analyzed the trend and variation of the total-factor energy efficiency in the 23 Guizhou industrial sectors of China with statistical data during 2004-2008. The results show that the general improvement of energy efficiency in these sectors benefits from the powerfully driven by the technical progress growth, but the pace and speed of the advancement in energy efficiency is slowed down due to the technical efficiency growth relatively lags behind the technical progress growth, and should focus on the improvement of pure technical efficiency to promote the technical efficiency growth. There are certain advantages of the economy and scale in the labor-intensive and monopoly sectors, the effects that the technical progress growth promotes the improvement of energy efficiency is remarkable.
