Fuzzy Comprehensive Evaluation of Emission Trading based on AHP-CRITIC——Taking Jiangxi Province as an Example
To ensure that the emission trading system can fully exert its policy effect in Jiangxi province and realize the reasonable and efficient allocation of environmental resources.By constructing a comprehensive evaluation index system for emission trading,and using the analytic hierarchy process(AHP),criteria importance though intercriteria correlation(CRI-TIC),and fuzzy comprehensive evaluation methods to construct a comprehensive evaluation model for emission trading.Taking Jiangxi province as an example,the comprehensive score and grade evaluation of emission trading evaluation indicators are calculated.The results show that the overall evaluation score of emission trading in Jiangxi province is 3.495 2,which is at a relatively high level in the medium range and almost reaches a good level.Converted into a percentage,it is 69.904％.There is still much room for improvement.Specifically,the evaluation score for supervision effectiveness is 3.585 6,which is at a slightly above good level and higher than the overall level of emission trading in Jiangxi province.However,the three indicators of policy flexibility,innovation speed of environmental protection products,and market speculation degree are all at a medium level.The scores decrease in turn and are all lower than the overall level,which are 3.450 9,3.396 6,and 3.372 8 respectively.To further improve the level of emission trading in Jiangxi Province and achieve the goal of coordinated pollution reduction and carbon reduction,it is necessary to strengthen cross-regional collaboration and linkage,promote the secondary market of emission trading,and support the exploration of inter-regional cooperation models.
