中国对外贸易的隐含二氧化硫排放研究——基于进口非竞争型投入产出表的分析

Embodied SO_2 Emission in China's Foreign Trade ——An analysis based on non-competitive( import) input-output tables

文章通过构建中国1992—2007年(进口)非竞争型可比价格投入产出表,测算与分析了对外贸易对我国SO2排放的影响,并利用结构分解法研究了促进中国对外贸易隐含SO2排放增长的驱动因素。结果表明,1997年以来中国已经成为SO2的净输出国,且环境贸易条件呈现恶化的趋势,我国为促进对外贸易的发展付出了一定的生态代价。贸易规模的增长是促进贸易含硫量的迅速增加最主要的因素,各部门直接排放系数的下降对贸易含硫量有关键的抑制作用,而中间生产技术与进出口结构的变化对其影响较小。

Based on the non-competitive （import） constant price input-output tables, this paper has researched the SO2 emissions embodied in China＇s foreign Trade and its driving factors by using the structural decomposition method. The result indicates that China has become a net exporter of SO2 since 1997, and its environmental terms of trade have been being deteriorated. The growth of trade is the most important factor to promote the SO2 emissions, and the direct emissions coefficient of various departments caused the decline of SO2 emissions. However, other factors, including the changes of the composition of export and import, and intermediate technique caused small effects.
