摘要
通过耦合投入产出分析方法和结构分解模型,探讨2002~2010年区域碳排放转移的演变特征、驱动因素及其地理源特征。研究发现:2002~2010年流出和流入河南省的贸易隐含碳排放均处于不断增加的趋势,其中流出贸易隐含碳排放主要是受外部最终需求的影响,且主要集中在中国的中部和东南部地区,而流入贸易隐含碳排放则主要是受本地最终需求和本地最终产品结构的影响最为显著,且主要来源于中国的东部、东北部和中部地区。研究还发现,为减轻贸易对区域碳排放及其减排责任的影响,开展区域合作来共同减排比单个地区独自应对更为有利,但在区域合作中各地区的获益程度可能会有所差别。
Carbon emission embodied in trade plays an important role in reducing regional obligations towards carbon emission reduction in regional climate policy. Based on a multi-regional input-output analysis and structural decomposition method, this article analyzes the changes and geographic sources of the emissions embodied in trade in Henan Province, and examines how and why the EET changed in Henan Province in 2002-2010. Moreover, in policy terms, regional climate policy options that potentially reduce the impact of trade on individ- ual region like Henan Province are also discussed. One finding from this study is that with the significantly increasing of the emissions embodied in exports and emissions embodied in imports in Henan Province in 2002-2010 in China, for Henan Province, the trend in terms of the geographic separation of consumers and the pollution emitted during the production of consumable items is increasing significantly. Furthermore, in terms of the driving forces onthe embodied emissions changes, emissions embodied in exports is affected most by demand in the other regions of China and production in the local region, while emissions embodied in imports is largely determined by demand in the local region and production in the other regions of China. In addition, for Henan＇ s emissions embodied in exports, their geographic sources are be mainly located in the central part of China and the southeastem China, whereas the geographic sources of the Henan＇ s emissions embodied in im- ports are primarily concentrated in the east of China, northeastern China and the central part of China. Another important finding is that if regions like Henan Province take binding commitments as a part of a coalition, instead of as individual regions, then the impacts of trade can be reduced. Notably, however, the extent of reduction in a coalition varies in different regions. Therefore, it is necessary that those regions that benefit most should provide financial and technological aid to those regions that suffer most or benefit least in climate policy.
