An Empirical Study On The Environmental Impact Of The Clean Development Mechanism(CDM)

The Clean Development Mechanism(CDM)is an energy conservation and emission reduction project that is exploited together by developing and developed countries.China is the largest developing country in the world as well as the second largest emitter of greenhouse gases in the world.Since 2002 when the CDM projects carried out by our country,there are more than 5000 projects have been approved,which made a significant contribution for the development of global environment climate.At present,the thesis about impact assessment of CDM on environment are mainly focus on the perspective of sustainable development,and mostly using the evaluation index system for analysis on how to assess whether the influence of the local environment improvement during the project implementation or operation process is of great significance or not.This paper first sorts out the development status,characteristics and challenges of CDM in our country.According to different types of CDM projects,analyzing the mechanism of their impact on environmental efficiency.Secondly,using the super efficiency SBM-DEA model to estimate the environmental efficiency of 30 provinces in our country.Thirdly,taking the environmental efficiency value as an explanatory variable and using a double-difference model to examine whether the implementation of the CDM can improve the efficiency of the local environment or not.But the result is not significant as we expect.Fourth,analyzing the influencing factors that affect the efficiency of the environment.Both the level of economic development and technological level have positive effects on environmental efficiency,while the industrial structure,energy structure,regional factors,foreign investment and environmental efficiency are negatively correlated.At the same time,taking the CDM issuance as one of the influencing factors of environmental efficiency but it did not show significant results either.Finally,this paper summarizes and analyzes the policy suggestions on promoting the CDM and improving the environmental efficiency.
