国际贸易中与能源有关的CO2排放量已被研究人员利用投入产出分析框架广泛研究。这些研究往往是在特定的部门综合层次上进行的，所作的选择在很大程度上取决于经济和能源数据的可得性。我们分析了部门聚集对研究结果的可能影响。我们使用中国和新加坡的数据进行实证研究，在不同的部门汇总水平上估计其出口中包含的能源相关CO2排放量。这些研究的一个结论是，大约40个部门的水平似乎足以反映一国出口所含排放的总体份额。另一个发现是，在近似的“理想”的情况下，混合数据处理方法比均匀分布的数据处理方法产生更好的结果。还提出了其他调查结果和一些建议。(C)2009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 input-output analysis framework. These studies are often conducted at a specific level of sector aggregation and the choice made to a large extent is dictated by economic and energy data availability. We investigate analytically the possible effects of sector aggregation on the study results. We conduct empirical studies using the data of China and Singapore where energy-related CO2 emissions embodied in their exports are estimated at different levels of sector aggregation. A finding from the studies is that levels around 40 sectors appear to be sufficient to capture the overall share of emissions embodied in a country's exports. Another finding is that in approximating the "ideal" situation the hybrid data treatment approach produces better results than the uniformly distributed data treatment approach. Other findings and some recommendations are also presented. (C) 2009 Elsevier B.V. All rights reserved.
