中国多区域隐含碳贸易的核算和结构分解分析

Accounting and Structural Decomposition Analysis of Multi-regional Embodied Carbon Trade in China

文章利用多区域投入产出模型对中国八大区域2002年和2007年的隐含碳贸易进行了核算和结构分解分析,结果显示:一般情况下,各区域内部的隐含碳贸易量大于区域间贸易以及出口贸易的隐含碳贸易量;对全行业来说,一般情况下技术变化会引起隐含碳贸易量的减少,但是产业关联变化和贸易量变化会引起隐含碳贸易量的增加;对三次产业来说,各产业的技术变化、产业关联变化和贸易量变化对隐含碳贸易量的影响存在产业上的差异。

This paper uses the multi-regional input-output model to conduct accounting and structural decomposition analy- sis of the embodied carbon trade in China＇ s eight regions in 2002 and 2007. The analysis result is shown as follows： in general, the embodied carbon trade volume within every region is larger than that of the inter-regional trade and export trade; as for the whole industry, technological change will lead to a decrease in the embodied carbon trade, but changes in industrial relations and trade volume changes will lead to an increase in embodied carbon trade; for tertiary industries, the impact of technological change, in- dustry association and trade volume change on embodied carbon trade is different.
