基于 Theil 指数的中国省际间碳排放强度差异分析

运用Theil指数研究中国大陆30个省区2000—2010年间碳排放强度分布及其差异特征。结果表明:中国总体碳排放强度呈下降趋势,反映了近年来节能减排工作取得初步成效;但省际间碳排放强度差异存在增大的趋势,且主要是由区域间差异增大造成的;中国四区域间碳排放强度呈现"俱乐部收敛"的特征。地区间碳排放强度差异不断扩大,一方面增大了制定节能减排政策的难度,另一方面也为不同地区间在节能减排领域开展合作提供了有利条件。

Analysis on Differences of Carbon Emission Intensity of Each Province in China Based on Theil Index

This paper employs Theil index to analyze distribution of carbon emission intensity of each province from 2000 to 2010.The empirical results show that carbon emission intensity of China is declining,reflecting preliminary achievements of work on energy saving and pollutions reduction in recent years.But difference of carbon emission intensity in different provinces is increasing,which is mainly caused by difference of carbon intensity between regions.Carbon emission intensity of the four areas appears "club convergence" characteristics.The difference of carbon emission intensity of each province and region increase indicating that it is more difficult to make a scientific and reasonable scenario on energy saving and emission reduction;On the other hand,it provides a condition for the cooperation in the energy saving and pollutions reduction fields among the provinces and regions with different carbon emission intensity.
