Efficiency of electricity use and productivity change of electricity in China: A nonparametric approach

This paper tries to investigate efficiency of electricity use of 30 administration regions and productivity change of electricity in China for the period 2003-2008. We use the Data Envelopment Analysis (DEA) method to measure the efficiency of electricity use and productivity change of electricity. From an empirical perspective, we provide a framework to investigate the situation of relative efficiency of electricity use and the growth rate of electricity’s productivity. The results indicate that the efficiency gap between regions is very large and the east areas have a higher level of electricity efficiency than the western areas. Moreover, both the technical and efficiency change in China from 2003 to 2008 is also slow. Based on these results, we propose some reasons behind and also give some suggestions about it.
