国际贸易中与能源有关的CO2排放已被研究人员利用环境投入产出框架广泛研究。尽管研究者对多区域投入产出模型的研究兴趣越来越大，但很少有研究探讨反馈效应的机制。我们介绍了一种方法，称为逐步分配的排放体现在贸易（SWD-EET），以揭示如何体现在贸易中的排放吸收一个国家的最终需求，通过一系列的分配步骤。基于该方法还研究了一国与其他国家双边贸易排放的间接吸收模式和间接贸易平衡。利用亚洲经济体数据进行的一项实证研究表明，由于国际贸易的反馈效应，一些经济体的“基于消费的”排放量估计数存在很大差异。在SWD-EET分析中，调整程序的第一步或前两步可以很大程度上捕捉到差异。还提出了其他调查结果和一些建议。(C)2011爱思唯尔有限公司版权所有。
Energy-related CO2 emissions embodied in international trade have been widely studied by researchers using the environmental input-output framework. Despite the increasing interest in using the multi-regional input-output (MRIO) model by researchers, few studies have looked into the mechanism of feedback effects. We introduce a method called the stepwise distribution of emissions embodied in trade (SWD-EET) to reveal how the emissions embodied in trade are absorbed by a country's final demands through a series of allocation steps. A country's indirect absorption patterns and its indirect trade balance of emissions from bilateral trade with other countries are also studied based on the proposed method. An empirical study using the data of Asian economies shows significant differences in the "consumption-based" emission estimates for some economies due to feedback effects through international trade. The differences can be largely captured by the first step or the first two steps of the adjustment procedure in the SWD-EET analysis. Other findings and some recommendations are also presented.
