基于投入产出分析的中国产业完全碳排放研究

Analysis on Complete Carbon Emission of China's Industries Based on Input-output

通过定义直接排放系数和完全排放系数,建立产业完全碳排放分析框架。基于2007年中国投入产出数据和能源统计数据,对各产业的碳排放特征进行分析与比较。结果表明,部分产业直接排放系数靠后、完全排放系数居前,属于碳排放较为隐蔽的产业;部分产业的两系数都居前,属于碳排放较为明显的产业。立足于节能减排的角度,这两类产业都是控制能耗和碳排的重要产业。从总量的角度来讲,建筑业是满足国内需求的第一碳排放产业;从进出口贸易角度来讲,通信设备、计算机及其他电子设备业则是碳排强度最为显著的部门。研究结论说明,完全排放系数更能全面反映一个产业的碳排放状况。直接排放系数和完全排放系数之间的差异,反映了产业隐蔽的间接排放。最后,从产业政策、贸易政策、综合经济管理政策方面对节能减排政策的制定给出了一些建议。

This article establishes a useful analytical framework concerning complete carbon emission of the industries inChina and then compares their characteristics in carbon discharge respectively based on the latest data derived from China＇s IO Table and Energy Statistics in 2007. Some are ＂much--carbon＂ sectors from any aspects： directly--embodied coefficient or perfectly--embodied coefficient. While, others are concealed ＂much--carbon＂ sectors： there are big difference between the coefficient above. From the perspective of the total, construction is the first to satisfy domestic demand; communication equipment, computer and other electronic equipment industry is the most significant trading department. Studies suggest that perfectly--embodied coefficient shows the situation of carbon emissions more comprehensively and accurately. The difference between directly--embodied coefficients and perfectly--embodied coefficient reflects the concealed indirect emissions. Finally, this article provides suggestions with respect to industrial strategies and the comprehensive economic management in order to effectively achieve energy conservation and emission reduction.
