Efficiency effect of changing investment structure on Chinas power industry
- 经济学院－已发表论文 
Based on data of Chinas power industry from 2005 to 2010, this research applies the SBM approach of the dynamic DEA model (one of the efficiency measurement methods that corresponds with economy-energy-environment trinity) to analyze the Energy-Efficiency-Dynamic Total Factor Productivity (ECDTFP 1) of the power industry and the efficiency effect of changing investment structure on the industry. The results indicate that the introduction of foreign capital and the reform to lower the share of state investment are conducive to raise the ECDTFP in the power sector. In addition, it is important to focus on vital factors such as the production structure, the industry concentration and the regional technology investment intensity, which significantly affect the productivity of the power sector in future policies and reforms. ? 2014 Published by Elsevier Ltd.
