中国物质资源消费区域差异的测度及分析

Measurement and analyses of regional differences in material consumption in China

区域资源环境不平衡是中国发展面临的突出问题之一。该文基于修正的原始资源消耗当量的测算结果和Gini系数法,对2010—2015年中国人均物质资源消耗的区域不平衡进行了测度和空间分解,并比较了物质资源消耗、温室气体排放和GDP在区域分布、不平衡模式上的异同。结果表明:中国人均物质资源消耗和温室气体排放的区域不平衡模式有一定相似性,组内差异和组间差异对Gini系数的贡献率均为25%~30%;但与中国GDP和全球温室气体的不平衡模式有显著差异。

The inequality of regional resources and environments is one of the most pressing problems for China’s development.The adjusted raw material consumption method and the Gini coefficient were used to measure and spatially decompose the inequality in per capita material consumption,greenhouse gas emissions and GDP at the regional scale in China during 2010 to 2015.The paper also compared the material consumption with the greenhouse gas emissions and GDP at the regional level to identify inequality patterns.The results show that the inequality pattern of the per capita material consumption in China’s provinces is similar to the per capita greenhouse gas emissions in China,where inter-regional and intra-regional components both contribute 25%-30%to the Gini coefficient.The results also show significant differences between China’s GDP and global greenhouse gas emissions.
