Beijing has witnessed rapid increase in energy consumption and lower energy intensity, its energy consumption elasticity remains below one, so, how is the total-factor energy efficiency(TFEE) in Beijing? This paper takes input-oriented Data envelopment analysis(DEA) to evaluate Beijing’s TFEE from 1991 to 2009 as compared with China’s average level. Furthermore, we use Grey relational analysis(GRA) to explore the driving factors of Beijing’s TFEE. The result shows: (1) The TFEE in Beijing has been rising from 1991 to 2009. (2) The main driving factors of the improvement are the restructure of its local industries and technical advances.
