- Abstract
As the largest energy consumer, China is facing increasingly great pressure to guarantee energy supply and energy security, which puts higher demand for measuring and improving energy efficiency. DEA model has become a widely accepted method in measuring energy efficiency at the macro-economy level. Considering the maximum of desirable outputs, this paper develops a new DEA model based on super-efficiency evaluation. In view of the significant relationship between DEA efficiency and the Pareto solution, the effectiveness of the new DEA model and Pareto Optimality are analyzed. In addition, the new DEA model is utilized to study the development of China’s energy efficiency of 21 years period from 1991 to 2011. The results show that China’s energy efficiency has experienced such a trend as “down – rise - stationary wave -rise”. Compared with the two classical models, the results are much more consistent with the real change trend, which indicates that the accuracy of the new DEA model is improved. The analysis of the influence factors by the Tobit model shows that the rising of energy price and technology progress can increase the efficiency. Finally, based on the research results, this paper gives some policy recommendations on increasing China’s energy efficiency.
