Abstract:

The efficiency assessment index system of the investment in the environmental governance was built based on the principles for building an assessment index system after the correlation researches.The total investment in the environmental governance was selected as the input indicator,and the control performance of water,gas,solid and other aspects as the output indicators.The efficiency assessment model was constructed based on data envelopment analysis (DEA).And the key influence factor was attained based on the grey incidence degrees between the DEA efficiency factor and each assessment index.The efficiencies of thirty provinces in China in 2009 were analyzed based on the data collected from China Statistical Yearbook on Environment 2010 and China Statistical Yearbook 2010.The efficiency of the investment in the environmental governance of each province was calculated,and its key influence factors were obtained.It is proved that the efficiency will be improved efficiently by controlling the key influence factors,such as the total investment in the environmental governance
