考虑减排潜力的中国省域碳排放权分配研究OA北大核心CHSSCDCSSCICSTPCD

Against the background of China's goal of achieving carbon peaking by 2030,the improved ZSG-DEA model is used to consider the emission reduction potentials of each province(autonomous regions and municipalities)and explore a provin-cial allocation scheme of carbon emission rights that takes into account both fairness and efficiency,in order to address the issue of rational allocation of carbon emission rights.The results of the study show that:(1)China's emission reduction potential varies a-mong regions,with the eastern region having a larger emission reduction potential,the western region having a larger gap within the emission reduction potential group and 50%of the low emission reduction potential group being concentrated in the western region,the overall emission reduction potential of the central region being insufficient,and the northeastern region being concentrated in the medium-and low-efficiency emission reduction potential groups.(2)The improved ZSG-DEA model calculates the emission re-duction coefficients in a more reasonable way,shrinks the gap in emission reduction pressure,and can reduce the difficulty of poli-cy implementation by narrowing the degree of inequality between provinces(autonomous regions and municipalities).(3)The syn-thesis of emission reduction potential and emission reduction coefficients reveals that some provinces(autonomous regions and mu-nicipalities),such as Henan,are still in the state of low potential and high emission reduction,and are facing the dilemma of bei-ng unable to effectively reduce carbon emissions on their own,while some regions still have"spare capacity"in carbon emission reduction.Based on the above conclusions,the article puts forward the following suggestions:each region should make use of its own advantages to contribute to carbon emission reduction;when arranging provincial carbon emission credits,it should pay atten-tion to the emission reduction potentials of different provinces(autonomous regions and municipalities);at the same time,it should strengthen the sense of responsibility for emission reduction,and promote the cooperation between regions.
