近年来,CO2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CO2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7 201.89×104 t,进口的结构变动效果综合后为-3 124.27×104 t;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40.34×104 t(32.21×104 t),2005—2008年阶段是-3 428.33×104 t(-4 942.21×104 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。
In recent years, excessive emissions of greenhouse gases such as CO2 are increasingly valued by countries all over the world. This article analyzes the CO2 content of foreign trade in Zhejiang Province in recent years. The net exports of carbon content and its share of the province’s carbon emissions have shown an increase in the proportion of both the import and export of the scale of the effect of all positive changes in the two periods of import and export structure of the effect of change Significantly different from 2005 to 2008, the structural change effect of exports for the 7 201.89 × 104 t, the import effect of structural changes after the comprehensive integration of -3 124.27 × 104 t; at this stage, the intermediate input change effect has been significantly improved, 2002 - The effect of the change in the input into and out of the country in 2005 is 40.34 × 104 t (32.21 × 104 t), and -3,428.33 × 104 t (-4 942.21 × 104 t) in 2005-2008. The carbon emissions per unit of GDP The effect of quantity change has also been significantly improved, and the effect of the change of carbon emissions per unit of GDP during the two periods is mainly determined by the effect of energy consumption per unit GDP. The effect of carbon emissions per unit of energy consumed by the import and export in both periods is very small .
