| 摘 要： 在国内国际双循环新发展格局下，研究对外贸易隐含碳排放及省际碳转移问题对实现“双碳”目标至关重要。利用最新编制的中国地区投入产出表，尝试从对外贸易与省际贸易两个维度考察中国31个省份的碳排放转移，并在分析不同省份对外贸易碳排放流动关联性的基础上，进一步揭示其省际碳转移方向存在差异的原因。研究发现：从中国31个省份碳排放转移模式来看，浙江、广东、江苏等沿海省份由对外贸易引起的净碳流入可通过省际贸易向外转移，山西、内蒙古、河北等内陆省份间的碳转移是由省际贸易主导；中国对外贸易隐含碳排放呈净流入状态的主要原因是出口的工业制成品隐含碳含量较高，而省际碳转移则主要集中于初级产品贸易；从测算结果来看，大多数省份进出口产品的碳贸易条件CTT>1，表明比进口更为“肮脏”的出口结构不利于碳减排目标的实现，省际碳贸易条件以及碳排放强度的显著差异是影响各省份碳转移流向的重要因素。基于研究，制定差异化碳减排政策，加快推进省际合作碳减排机制建设，将有助于外贸低碳化发展。 |

| Abstract: Under the background of the new development pattern of domestic and international dual cycle, research on the issues of carbon emissions implied by foreign trade and inter-provincial carbon transfer is very critical to achieving the "dual carbon" goal (carbon emission peak, carbon neutrality). Adopting the newly compiled regional input-output table of China, this paper attempts to investigate the carbon emission transfer of 31 provinces in China from two dimensions of foreign trade and inter-provincial trade, and, based on the correlation of carbon emission flow of different provinces in foreign trade, further reveals the reasons for the differences in the direction of inter-provincial carbon emission transfer. The results show that from the perspective of the carbon emission transfer pattern of 31 provinces in China, the net carbon emissions of Zhejiang, Guangdong, Jiangsu and other coastal provinces caused by foreign trade can be transferred outward through inter-provincial trade, while the carbon emission transfer of Shanxi, Inner Mongolia, Hebei and other inland provinces is mainly dominated by inter-provincial trade, that the main reason for the net inflow of embodied carbon emissions in China's foreign trade is that the carbon embodied in exported manufactured goods is |
