Regional Environmental Governance Efficiency Research in China based on the DEA and Malmquist Index

By selecting input and output indicators,this paper firstly analyzes the environmental governance efficiency in domestic 30 provinces(except Tibet) in 2010 and 2011 by using DEA method static analysis,and then analyzes the sequence data of China's 30 provinces(except Tibet) from 2002 to 2011 by using the Malmquist index dynamic analysis,which based on dynamic time series of China regional environmental governance efficiency change.The paper finds that,based on the static time,in 2010 and 2011,there are large investment,yield small resources waste phenomenon in the domestic provinces,which leads to low efficiency of regional environmental governance.Based on dynamic time,China's overall regional environmental efficiency declines,the average TFP index is only 0.955 in past 10 years.The results also show that the technical efficiency of China is the leading elements for restricting the regional environmental governance efficiency,therefore it should be appropriate to increase investment of science and technology,in order to improve the efficiency of environmental management.
