作为全球第二大与能源相关的二氧化碳排放国，中国在1991年至2000年经历了二氧化碳排放强度的急剧下降，但此后下降速度放缓，2003年二氧化碳排放强度实际上有所上升。本文利用Sun提出的完全分解方法，分析了1991-2006年与能源有关的二氧化碳排放量和二氧化碳排放强度变化的影响因素的性质。研究发现：(1)能源强度效应是CO2排放量和CO2排放强度下降的主要贡献者，(2)经济活动效应是CO2排放量增加的最主要贡献者，(3)经济结构和CO2排放系数效应对CO2排放量和CO2排放强度的影响不大，在1991-2006年期间，除个别年份外，经济结构和CO2排放系数效应实际上增加了CO2排放量和CO2排放强度。
As the country with the second largest emitter of energy-related CO2gas, China experienced a dramatic decline in CO2emission intensity from 1991 to 2000, but since then the rate of decline slowed and CO2emission intensity actually increased in 2003. In this paper, the complete decomposition method developed by Sun is used to analyze the nature of the factors that influence the changes in energy-related CO2emission and CO2emission intensity during the period 1991–2006. We find that: (1) energy intensity effect is confirmed as the dominant contributor to the decline in CO2emission and CO2emission intensity, (2) economic activity effect is the most important contributor to increased CO2emission, and (3) economic structure and CO2emission coefficient effects are found to contribute little to the changes in CO2emission and CO2emission intensity, which actually increased CO2emission and CO2emission intensity over the period 1991–2006 except for several years.
