Abstract:

With the DEA method,this paper makes a study on energy efficiency differences in Chengdu-Chongqing economic zone. Taking the total energy consumption,capital stock and labor force in 2013 as input variables and the GDP as output variable,we calculated the energy efficiency of 16 cities in Chengdu-Chongqing economic zone and analyzed the distribution of energy efficiency and the differences of energy efficiency among them as well as the causes of the differences between cities. The results show that among the 16 cities in Chengdu-Chongqing economic zone,the energy efficiency scale of Chengdu and Chongqing are at the stage of constant return to scale,while other cities are at the stage of increasing return to scale. The cities with higher energy efficiency are comparatively better developed,which means energy efficiency and economic development level are closely related. Moreover,the energy efficiency of Chengdu-Chongqing economic zone exhibits a“Dual Core”space distribution and tier structure with great energy efficiency differences among the cities. Therefore,it is necessary to design the space structure of Chengdu-Chongqing economic zone,and to speed up the industrial structure adjustment and upgrading process. Major efforts should made to promote technology innovation in energy conservation and emissions reduction,and to break down energy saving targets to smaller and more specific ones according to local conditions,so as to continuously improve the energy efficiency of Chengdu-Chongqing economic zone.

Key words: Chengdu-Chongqing economic zone;energy efficiency;DEA method;&ldquo, Dual Core&rdquo, space distribution;tier structure;energy conservation and emissions reduction
