基于碳转移的部门碳分配研究

Sector carbon allocation based on carbon transfer

摘要:

考虑到碳排放通过贸易发生转移的问题,有必要分别从生产者原则及消费者原则研究各部门的碳分配效率及帕累托最优时的最优碳配置。首先通IOA分析碳排放在产业间的转移特征,并基于此通过ZSG-DEA对碳分配进行估算。结果表明：(1)2015年生产者原则下6个部门的实际碳排放较其最优碳排放高,其他19个部门的实际碳排放则较低,第一、二产业需增加碳配额,第三产业则需减少碳配额；(2)而消费者原则下,8个部门的实际碳排放较其最优碳排放高,其他17个部门的实际碳排放则较低,第一产业需增加碳配额,第二、三产业则需减少碳配额；(3)生产者原则下各部门的调整幅度较消费者原则下大。因此,进行碳分配时必须把握部门间的异质性。

Abstract:

Considering the problem of carbon transfer through trade, various sectors’ carbon allocation efficiency and their optimal carbon emissions under Pareto Optimality require investigation from the producer accounting principle and the consumer accounting principle, respectively. The study first analyzed inter-industrial carbon transfer characteristics through IOA, and then estimated carbon allocation among sectors through ZSG-DEA. Results indicate that:(1)under the producer accounting principle in 2015, actual carbon emissions of six sectors were higher than optimal carbon emissions, the other 19 sectors were the opposite, the primary and secondary industries must increase carbon quotas, and the tertiary industry must reduce carbon quotas; (2) under the consumer accounting principle, actual carbon emissions of eight sectors were higher than optimal carbon emissions, the other 17 sectors were the opposite, the primary industry must increase carbon quotas, the secondary and tertiary industries must reduce carbon quotas;(3)carbon adjusted quotas of sectors under the producer accounting principle were relatively large. Therefore, the heterogeneity among sectors must be grasped for effective CO2 allocation.
