东亚地区产业垂直专业化、贸易细分与中国的贸易隐含碳

East Asian Vertical Specialization,Trade Segmentation and China's Embodied CO_2 Emissions

随着东亚地区产业垂直专业化程度的加深,中国在承接东亚地区产业转移的同时,也接收了大量的隐含碳排放。基于进口非竞争投入产出模型,将垂直专业化率引入碳排放测算模型,利用1995-2007年中国的产业、贸易和能源数据估算中国各行业的贸易隐含碳排放量,再结合中国产业各行业的垂直专业化指数,考察垂直专业化水平对各行业贸易隐含碳的影响。结果表明:产业垂直专业化率的提升导致了中国对外贸易隐含碳排放的增加;各产业部门的隐含碳排放与垂直专业化水平呈正向变动关系,在高碳产业中这一趋势更为明显,表明我国参与国际分工处于产品生产网络的高碳排放环节。

With the vertical specialization level in East Asia rising rapidly,China is taking industries transferred from East Asian developed economies,meanwhile,It also receives a lot of implicit carbon emis-sions. This paper uses the non-competitive input-output model and the VSS into analysis framework to cal-culate trade embodied carbon emissions and examines the influence of vertical specialization on China’s carbon emissions. The results show that：in general,the relationship between the carbon embodiment in trade and vertical specialization is positive,especially in carbon-intensive industries,which means China is still in the disadvantaged position of global production network with regarding to trade-embodied emissions.
