基于GE指数的中国地区碳排放差异分解

Decomposition of the Regional Differences of China's Carbon Dioxide Emissions Via GE Index

采用IPCC的方法,将化石能源细分为17种并考虑水泥生产测算了1997—2010年中国省际层面CO2排放量,从省际、东中西部和八大经济区域三个视角,运用GE指数组群分解方法实证研究了中国地区CO2排放强度差异状况。分解结果显示:总体差异主要由东中西部区域内的差异所解释,八大经济区域间的排放差异贡献了总体差异的大部分。

In this paper, we measure China^s provinciaMevel carbon dioxide emissions of 1997 2010 with IPCC method, and empirically study the regional differences of China^s carbon dioxide emissions intensity according to the GE indexes subgroup decomposition method from the three perspectives of provincial-level, East-central-west, and the eight economic regions. The results show that total difference is mainly explained by the differences within the eastern central and western regions, while differences between the eight economic regions contribute most of the regional differences of carbon dioxide emissions intensity in China.
