基于泰尔熵指数的区域碳排放差异研究

碳排放的区域差异研究,对各地区碳减排任务的合理分配及碳减排目标的顺利实现具有重要意义.基于泰尔熵指数系统分析了中国碳排放的区域分布特征及差异化程度,探索了中国东部、中部和西部不同区域碳排放效率的差异及成因.研究结果表明:中国碳排放整体呈现出人均碳排放量增加、碳排放强度降低的走向;碳排放效率总体呈现出东高西低,中部改善迅速的态势;中国各区域碳排放效率长期存在差距,西部地区的减排行为对中国整体的碳减排目标实现举足轻重.为中国碳减排任务的合理分解提供了经济及政策建议.

An Analysis on the Differences of Regional Carbon Emission in China Based on Theil Index

The study on the regional carbon emission differences is important to the reasonable allocation of the regional carbon emission reduction task and the smooth realization of the carbon emission reduction targets. The paper is based on the Theil index, which systematically analyzes the regional carbon emission distribution characteristics and differences, exploring the cause and effect of the carbon efficiency of the eastern, central and western regions. The results show that: China carbon emission efficiency is not evenly distributed in space; the per unit GDP carbon emission and per capita carbon emission have significant differences; the western area is the main region that contributes to the high national average carbon intensity which means it’s crucial to realize the western carbon emission targets. According to study above, the paper provides recommendations for reasonable carbon emission reduction task allocation and effective economic policies.
