Research on Chinese Regional Environmental Management Efficiency Based on DEA and Malmquist Index
Based on the analysis of 30 provinces ( except Tibet) in China , this paper used the environmental staffs' number, completed industrial pollution abatement investment amount, waste treatment facilities’ number, the three wastes’ comprehensive utilization output value, and harmless waste treatment capacity as input and output index. The paper evaluated the 30 provinces’ environmental management efficiency (except Tibet) in 2008 and 2009 by Data Envelopment Analysis, then analyzed the time series data of the 30 provinces from 2003 to 2009 by Malmquist index. Study finds that overall Chinese environmental management efficiency’s TFP index is 0.942 in 2009, and decreasing year by year. Besides, it shows that technology is dominant factor of restricting Chinese environmental management efficiency, So, we should increase the investment in science and technology as to improve the efficiency. In addition, the environmental management scale’ expansion and structure optimization are also necessary methods of improving the efficiency.
