摘　　要：国际贸易通过进口减少一国或地区的碳排放，通过出口增加其碳排放，综合考虑二者才能确定一国或地区是贸易l}碳排放受害者还是受益者。鉴于此，本文以北京市为例。估算其外贸中的隐含碳排放，并采用结构分解方法分析其纠贸隐含碳增长的原因。结果表明，2002—2007年，尽管出口商品结构优化和碳排放密度下降减少了北京市外贸隐奄碳排放，但是贸易规模的扩大却增加了北京市贸易隐含碳排放，最终导致北京市外贸进口和出口碳排放均呈上升建势，然而由于进口隐含碳大于出口隐含碳，并且碳排放贸易条件严格小于1，所以北京市通过外贸将碳排放转移到爿他国家，是外贸的碳排放受益者。International trade reduces a country or region＇ s carbon emissions through commodity imports and increases them by exports, which should be comprehensively considered to determine a country or region to be a trade victim or beneficiary of carbon emissions. In the case of Beijing, this article estimates the embodied carbon emissions in trades, and analyzes the reasons for the growth of embodied emissions in trades by using the structural decomposition method. The results show that, from 2002 to 2007, the optimized export structure and the decrease in carbon emission intensity had reduced embodied carbon emissions in Beijing＇ s trades, while trade expansion had increased its embodied carbon emissions in trades, leading to an upward trend in carbon emissions of both Beijing＇ s imports and exports. However, as embodied emissions in imports are more than those in exports and the terms of emissions in trades are less than 1, Beijing has become a trade beneficiary of carbon emissions by transferring carbon emissions to other countries through foreign trades.
