近年来，CO_2等温室气体的过多排放日益为世界各国所重视。文章对浙江省近年外贸中的CO_2含量进行分析研究。内涵碳的净出口量与其占全省碳排放的比值都呈现增加的势头；两个时期的进（出）口的规模变动效果全是正向；两个时期的进（出）口结构变动效果有明显差异，2005—2008年期间，出口的结构变动效果为7 201.89 × 10~4 t，进口的结构变动效果综合后为-3 124.27 x 10~4t;在此阶段，中间投入变动效果有明显的改善，2002—2005年进（出）口的中间投入变动效果是40.34 × 10~4 t(32.21 x 10~4 t)，2005—2008年阶段是-3 428.33 × 10~4 t（-4 942. 21 × 10~4 t）；单位GDP碳排放量变动效果也有明显改善，并且两个时期单位GDP碳排放量变动效果主要是由单位GDP能耗变动效果所决定；两个时期进（出）口单位能耗的碳排放量变动效果均非常小。 |

CO_2 emissions increased by about 80% from 1991 to 2001, with industrial sectors accounting for 55% of the increased amount. Among all the industrial sectors, iron & steel, petrochemicals, electronics, textiles, pulp & paper and cement account for approximately three quarters of the total industrial C0_2 emissions. As a result, understanding driving factors behind increasing CO_2 emissions in the six sectors is valuable to related policy formation. This paper applies two-tier input-output structural decomposition analysis (I- O) to analyze the sources of change of energy intensive industries' CO_2 emissions from 2002 to 2008. The result shows that: The net export of embodied carbon and the proportion of total domestic emissions are both increased; the export (import) scale effect of the two stages is both positive; the export (import) structure effect of the two stages is quite different. During the period 2005 to 2008, total export structure effect is 72.02 million tons, while total import structure effect is - 31.24 million tons; effect of intermediate inputs has greatly improved. The export (import) intermediate inputs effect is -34.28 (-49.42) million tons during the period 2005 to 2008, while it is 0.40 (0.32) million tons during the period 2002 to 2005; the effect of carbon emissions per unit output value is also significantly improved, and decided mainly by the energy consumption per unit output value effect; effects of export (import) carbon emissions per unit of energy during the two stages are very small. |
