利用结构分解分析(SDA)的加权平均分解法分析了4类增长因素对1992～2007年中国温室气体排放变化的影响.结果表明:总体上,最终需求规模扩大是引起排放增长的主要因素,其次是投入产出结构的改变,温室气体排放强度降低是减缓排放量的主要因素,最终需求结构改变对排放量变化的影响不明显.从部门角度看,建筑业和机械、电气、电子设备制造业是隐含温室气体排放增加的主要来源.从变化趋势看,2002～2007年温室气体排放增幅明显高于其他时期,出口和固定资本形成的大幅增长是推动这一时期排放增长的主要原因.
Structural decomposition analysis of the increase in China's greenhouse gas emissions.
Effects of four driving factors on greenhouse gas (GHG) emissions in China from 1992 to 2007 were studied by employing a weighted average decomposition method of structural decomposition analysis. The results showed that growth in final demand volume was the top determinant for the increase of emissions, followed by changes in input-output structure. Decrease in emission intensity was the major emission offset determinant. Changes in final demand structure contribute little to emission reduction. In terms of emissions from industry, the main sources of the embodied GHG emission increase were construction industry and machinery, electric and electronic manufacture industry. In terms of emission trend, the increase in GHG emission from 2002 to 2007 was much higher than that in other periods. Export and fixed capital formation, which increased dramatically from 2002 to 2007, were the main drivers.
