考虑技术效率的碳排放驱动因素研究

The Driving Forces of Carbon Emissions in Consideration of Technical Efficiency

利用距离函数和数据包络分析法测度要素相对效率,在此基础上构建了碳排放因素分解模型,该模型可以从13个方面来分析碳排放变化的驱动因素。实证研究表明,7个因素导致中国碳排放的减少,尤其是能源强度的降低和能源利用技术水平的提高。其余6个因素导致中国碳排放增加,尤其是人均资本的变化和资本技术效率的降低。

Abstract：Based on measuring the efficiency changes of inputs/outputs,we present a decomposition model by using dis- tance functions and data envelopment analysis. The components driving the change of carbon emissions are decomposed into the contributors from thirteen factors specified in this paper. The empirical results indicate that seven factors de- crease the carbon emissions, especially the change in energy intensity and energy utilization technical level. While the other six factors increase the carbon emissions, especially the change in capital per capita and capital technical efficien-
