中国对外贸易隐含碳增加值指数研究

Research on Embodied-Carbon and Value-Added Index of China’s Foreign Trade

中国在积极参与世界贸易、经济迅猛发展的同时,正面临着两重压力:一方面,中国一些行业正被锁定在国际价值分工低附加值的低端环节;另一方面,中国二氧化碳排放量跃居世界第一。论文基于全球价值链背景,将总贸易核算方法与世界环境投入产出模型结合,从国家整体层面、双边贸易层面、行业层面对2000—2014年中国进出口贸易的国内增加值和隐含碳排放量分别进行了核算,并构建了隐含碳增加值指数,由此发现国际社会高估了中国的碳减排责任,中国进一步的减排重点在于能源部门。

While actively participating in world trade and achieving rapid economic development,China is facing two pressures:on the one hand,some industries in China are being locked in the low-end with fewer value-added of international value division;On the other hand,China’s carbon dioxide emissions jump to the top in the world.Based on the GVC background,combining the total trade accounting method with the world environmental input-output model,this paper calculates the domestic value-added and embodied carbon emissions of China’s import and export trade from 2000 to 2014 from the national overall level,bilateral trade level and industry level,and constructs a new index named embodied-carbon and value-added index.It found that the international society overestimated China’s carbon emission responsibility,and it is energy sectors’main task to reduce China’s further emission.
