【摘要】 本文利用投入产出模型计算分析了外贸对中国CO2排放的影响,发现中国隐含碳净出口的绝对数量及占国内总排放之比都增长较快。从因素分解结果来看,贸易规模的扩大是贸易过程中隐含碳增加的重要原因,两阶段规模效应皆为正向。同时,节能减排取得一定的成就,2002～2005年各部门技术效应有较大的差异,其中出口总技术效应为正向,进口总技术效应却为反向,但2005～2007年各部门的技术效应均为反向。另外,贸易结构也至关重要,2005～2007年出口总结构效应为正向,但进口总结构效应却为反向。2005～2007年进口总技术效应与结构效应之和超过了规模效应,使得隐含碳总进口减少。更多还原

【Abstract】 By means of an input-output model,the paper made a case study on the impact of foreign trade on China’s emission of CO2,and found that China’s net export of Embodied Carbon have increased rapidly.The result shows that,the expansion of trade scale is the important reason of the increase of embodied carbon.At the same time,there is a certain achievement of the technology of emission reduction,the technological effect is quiet different between sectors during 2002 to 2005,the total technical effect of exports is forward while the total technical effect of imports is reverse,but the technical effect of all departments are reverse during 2005 to 2007.Moreover,the trade structure is also very important.The total structure effect of exports is forward while the total structure effect of imports is reverse.The sum of total technical effect and structure effect surpassed the scale effect during 2005 to 2007,reduce the embodied Carbon of import.更多还原
