分析区域间虚拟碳流动的特征对于中国制定有效的区域减排战略至关重要。本研究建立了多区域投入产出模型，评估区域间碳流动特征，并根据一种生产型和两种消费型核算原则核算不同区域的碳排放。结果表明，区域间碳流量从2002年的136.4MtC增长到2007年的377.8MtC。区域间碳流量占全国排放总量的比例从2002年的15.2%上升到2007年的21.1%。因此，不同的核算原则对一个地区承担的排放责任的影响往往越来越不同。根据不同核算原则下的结果，东北地区和西北地区在生产核算原则下需要承担的排放责任远大于消费核算原则下的排放责任。相比之下，东部沿海和南部沿海地区则需要在两种基于消费的原则下承担更大的排放责任。此外，无论是2007年区域间碳流量总量还是2002-2007年区域间碳流量增长量，中部和西北地区向东部沿海地区的碳流量贡献最大。鉴于这种情况，并考虑到这些区域之间的经济差距，在讨论区域排放责任时可以考虑类似联合执行的方法。结果还表明，完全利用直接排放原则是一种更可行、更实用的基于消耗的选择。 (C) 2014 Elsevier Ltd. 保留所有权利。
Analysing the characteristics of virtual carbon flows among regions is essential for China to deploy effective regional mitigation strategies. This study established a multi-regional input output model to assess the characteristics of interregional carbon flows and account for carbon emissions by different regions according to one production-based and two consumption-based accounting principles. Results indicate that interregional carbon flows grew from 136.4 MtC in 2002 to 377.8 MtC in 2007. The proportion of total national emissions represented by interregional carbon flows rose from 15.2% in 2002 to 21.1% in 2007. Therefore, different accounting principles tend to have more and more different impacts on the emission responsibility that a region is assumed to take. According to the results under different accounting principles, the Northeast and Northwest regions will need to assume much greater emission responsibilities under the production-based principle than under either of the consumption-based principles. The Eastern Coastal and Southern Coastal regions, in contrast, will need to assume much greater emission responsibilities under the two consumption-based principles. Moreover, the carbon flows from the Central and Northwest regions to the Eastern Coastal region were the greatest contributors to both the total interregional carbon flows in 2007 and the growth in interregional carbon flows from 2002 to 2007. Given this situation and considering the economic disparity among these regions, methods similar to the Joint Implementation could be considered when discussing the regions' emission responsibilities. Results also indicate that the total use direct emission principle is a more feasible and practical consumption-based choice. (C) 2014 Elsevier Ltd. All rights reserved.
