1990年から2021年までの多地域環境産業連関モデルを用い、115カ国の製造業付加価値貿易ネットワークと内包炭素排出を分析。先進国が中心で新興国の台頭が見られ、貿易関連排出は急増し、途上国に過重な環境負荷が生じる炭素不平等を明らかにした。
English
Using a multi-regional environmental input-output model from 1990 to 2021, this study analyzes the global manufacturing value-added trade network and embodied carbon emissions across 115 countries. It reveals stable network structures with developed countries central, rising emerging economies, and growing trade-related emissions, highlighting carbon inequality where developing countries bear disproportionate burdens.

附加值与隐含碳排放的流动是国际贸易中的重要议题。本研究利用多区域数据库构建了1990年至2021年的环境投入产出模型，分析了全球制造业附加值贸易网络及115个国家（地区）的隐含碳排放，并考察了主要国家的污染贸易条件和出口产品状况。结果表明，该网络保持稳定，发达国家（包括美国、日本和德国）占据核心地位，而新兴经济体（包括中国和俄罗斯）取得了显著进展。与贸易相关的碳排放急剧上升，揭示了碳不平等现象，即发展中国家承担了不成比例的环境负担。此外，美国与中国之间的附加值和隐含碳流动呈现出分化趋势。这些发现增进了对贸易与环境关联的理解，并为全球碳减排提供了见解。

📄 Abstract（原文）
The flows of value-added and embodied carbon emissions are significant issues in international trade. This study utilizes the multi-regional database to construct an environmental input-output model from 1990 to 2021, analyzing the global manufacturing value-added trade network and embodied carbon emissions of 115 countries (regions). It also examines pollution trade conditions and export product situations of major countries. Results show that the network remains stable, with developed countries (including the United States, Japan and Germany) occupying central roles, while emerging economies (including China and Russia) have made significant progress. Trade-related carbon emissions have risen sharply, revealing carbon inequality as developing countries bear disproportionate environmental burdens. Furthermore, the flows of value-added and embodied carbon between the United States and China show divergent trends. These findings enhance understanding of the trade – environment nexus and provide insights for global carbon reduction.
