为探讨“十一五”期间（2006-2010年）中国CO2排放变化的主要驱动因素，寻求减少CO2排放的主要途径，采用生产-理论分解分析方法对能源相关CO2排放变化进行分解。结果表明：第一，经济增长和能源消费是样本期内CO2排放增加的两大驱动因素，特别是在煤炭资源消耗巨大的北方沿海、西北和中部地区，其能源消费对CO2排放的驱动作用较为明显。第二，碳减排技术的改进和能源强度的降低对碳排放的抑制作用显著，且碳减排技术的效果相对更为显著。第三，能源使用技术效率、能源使用技术和碳减排技术效率对CO2排放的总体影响较小。最后，对我国政府今后降低CO2排放强度提出了政策建议。
In order to investigate the main drivers of CO2emissions changes in China during the 11th Five-Year Plan period (2006–2010) and seek the main ways to reduce CO2emissions, we decompose the changes of energy-related CO2emissions using the production-theoretical decomposition analysis approach. The results indicate that, first, economic growth and energy consumption are the two main drivers of CO2emissions increase during the sample period; particularly in the northern coastal, northwest and central regions, where tremendous coal resources are consumed, the driving effect of their energy consumption on CO2emissions appears fairly evident. Second, the improvement of carbon abatement technology and the reduction in energy intensity play significant roles in curbing carbon emissions, and comparatively the effect of carbon abatement technology proves more significant. Third, energy use technical efficiency, energy use technology and carbon abatement technical efficiency have only slight influence on CO2emissions overall. In the end, we put forward some policy recommendations for China’s government to reduce CO2emissions intensity in the future.
