基于分组集中DEA的中国省区碳排放权分配研究

Allocation of Carbon Emission Rights in China's Provinces Based on Grouped Centralized DEA

以中国省区碳排放权分配为研究对象,依据公平与效率的综合原则,构建基于分组集中DEA的分配方案。基于总量控制原则,首先采用层次聚类根据省份特征进行分组,再结合熵值法的碳排放权初步分配结果计算各组分配总量,最后构建集中DEA模型对中国各省份的碳排放权进行组内再分配,并且测度了此分配方案的公平性。结果表明:(1)减排高压与中压地区由于不合理的能源结构、较高的能源依赖或较低的能源利用率等原因导致了碳排放量增长,带来了一定的减排压力;(2)基于分组集中DEA的碳排放权分配方案在实现效率最优化的同时考虑了省份间的公平分配,此方案兼顾了效率与公平。

This paper takes the allocation of carbon emission rights in China's provinces as the research object and con-structs the allocation scheme based on grouped centralized DEA according to the comprehensive principles of fairness and ef-ficiency.Based on the principle of total amount control,firstly,hierarchical clustering is used to group according to the char-acteristics of provinces,then combined with the preliminary allocation results of carbon emission rights based on the entropy method to calculate the total allocation of each group,and finally,a centralized model is constructed to redistribute the carbon emission rights within the group,and the fairness of this allocation scheme is measured.The results show that:(1)Regions with high and medium emission reduction pressure have increased carbon emissions due to unreasonable energy structure,high energy dependence,or low energy utilization rate,which brings pressure on emission reduction;(2)The carbon emission right allocation scheme based on grouped centralized DEA considers the fair distribution among provinces while achieving ef-ficiency optimization,balancing the efficiency and fairness.
