国际贸易对国家脱碳结果的影响尚无定论。以德国为例，基于全球价值链框架，对产业间联系进行了分析。我们确定了由于分散的贸易网络的组成，规模和技术的转变而导致的国家排放变化。结果表明，在减排过程中，一方面，地方排放密集部门对国内经济和国际贸易的供给萎缩。另一方面，我们发现下游部门的生产推动了全面的排放强度降低，即使在落后的GVC参与中存在碳泄漏。然而，当排放密集型生产集中在当地市场时，全球价值链的后向参与对当地经济的排放密集度产生积极影响。根据研究结果，我们认为，持续的技术创新和价值链的重建是从地方经济到全球经济可持续脱碳的必要条件。
The impact of international trade on national decarbonization outcomes is inconclusive. Taking Germany as a case study, we developed a relative intersectoral linkage analysis based on the global value chain (GVC) framework. We identified nations' emission changes due to the transition of composition, scale, and technology in the fragmented trade network. The results show that in the process of reducing emissions, on the one hand, the supply of local emission-intensive sectors to the domestic economy and international trade has shrunk. On the other hand, we found comprehensive emission intensity reduction driven by downstream sectors' production, even if there was carbon leakage in the participation of backward GVCs. However, when emission-intensive production was concentrated in the local market, GVC backward participation positively affected the emission intensity of the local economy. According to the findings, we assert that continuous technological innovation and reconstruction of the value chain are necessary for sustainable decarbonization from the local to the global economy.
