Abstract: In this paper, improving traditional three-inputs model to four-inputs model, which including human capital, we use CRS-based DEA method to calculate energy efficiency of thirty districts in China from year 2005 to 2012. Further, we use fixed-effects panel data model to empirically analyze the effects of economic growth level, industrial structure, openness level, ownership structure, energy structure and technology level.

Key words: energy efficiency, DEA method, fixed-effects panel data, human capital
