全球碳排放的区域差异与收敛性分析

Analysis on the Regional Difference and Convergence of Global Carbon Emissions

本文以1992～2008年的数据为基础,采用经济增长收敛理论,分析了世界206个国家的碳排放量、人均碳排放量和碳排放强度等指标的分布特征,以及178个国家或地区指标的收敛性。研究表明:①世界各国碳排放量、人均碳排放量和碳排放强度差异很大,收入水平越高的国家其碳排放量和人均碳排放量越大;除重债穷国碳排放强度低于高收入国家外,收入水平越高的国家其碳排放强度越低。②世界碳排放强度和人均碳排放量都存在17阶段(年)的σ收敛,而世界各国碳排放量的差距在不断扩大。③全球碳排放量、人均碳排放量和碳排放强度都具有β绝对收敛性。

With the data of 206 countries all over the world from 1992 to 2008, we analyzes the distribution characteristics of carbon emissions, per capita carbon emissions and carbon emissions intensity indexes by using the economic growth convergence theory, as well as the convergence characteristics of indexes in 178 countries or regions. The studies indicate： ①carbon emissions, per capita carbon emissions and carbon emissions intensity are different among the countries, the higher national income level is , the more carbon emissions and per capita carbon emissions are, and excepting the heavily indebted poor countries, the higher national income level is, the less carbon emissions intensity is.②The convergence of 17 stages （years） are existent for the carbon emissions intensity and per capita carbon emissions of the global, and widening gap of carbon emissions be- tween the countries in the world. ③β-absolute convergence of the carbon emissions, and per capita carbon emissions as well as carbon emission intensity are existent.
