本文将1991-2006年中国能源相关CO2排放量分为三个等时间段进行分解分析。采用孙先生提出的完全分解方法，分析了CO2强度、能源强度、结构变化和经济活动四个因素的性质。结果表明，在所有主要经济部门中，经济活动对CO2排放变化的正向影响最大，中国实现了CO2排放的大幅下降，主要原因是能源强度的提高。但是，CO2强度和结构变化的影响相对较小。结构变化仅对农业部门的CO2减排产生了积极影响，而交通运输部门的CO2排放强度也对CO2减排产生了积极影响。此外，本文还提出了中国CO2减排量的计算公式，表明中国对全球CO2减排做出了重要贡献。
This paper presents a decomposition analysis of energy-related CO2emission in China for the period 1991–2006 divided into three equal time intervals. The complete decomposition method developed by Sun is used to analyze the nature of the four factors: CO2intensity, energy intensity, structural changes and economic activity. The results show that economic activity has the largest positive effect in CO2emission changes in all the major economic sectors and China has achieved a considerable decrease in CO2emission mainly due to the improved energy intensity. However, the impact of CO2intensity and structural changes is relatively small. Structural changes only exhibit positive effect to the CO2mitigation in agricultural sector, and CO2intensity also contributes to the decrease of CO2emission in transportation sector. Moreover, a formula about CO2mitigation is presented in this paper, which shows that China has made a significant contribution to reducing global CO2emission.
