Abstract: The improvement of construction energy efficiency has an important significance for the sustainable development of construction industry. According to the framework of total factor energy efficiency, a DEA model is built to study China's inter-provincial energy efficiency of construction industry during 2005-2010. The results have shown that, during this period, the average energy utilization efficiency of China's construction industry has increased to a certain extent, but technological progress innovation only has limited impact of on the improvement of energy efficiency; there are significant differences in regional energy efficiency, obviously inefficient utilization of energy in construction industry has been observed among central and western regions. Finally, the impacts of industrial structure, energy structure, competiveness of enterprises and technical level on the inter-provincial differences of construction energy efficiency have been studied, and some energy-saving recommendations for construction industry are put forward.

Key words: DEA model; energy efficiency; technological innovation; energy-saving
