Decarbonisation and specialisation downgrading: The double harm of GVC integration
研究了全球价值链整合如何通过国际分工同时加剧碳排放和导致发展中国家产业与生态降级，对政策制定者评估贸易与环境政策有参考价值。
This study explores the double harm of Global Value Chain (GVC) integration by analysing the link between the international division of productive activities and emissions. Methodologically, we propose a framework to disentangle the developmental and sectoral origins of CO 2 emissions within GVCs. By providing a granular decomposition of domestic and foreign contributions, we identify foreign backward linkages as the primary carriers of CO 2 emissions along GVCs, surpassing domestic inputs in their CO 2 footprint. From a within-country perspective, we examine how a country’s internal production structure shapes CO 2 emission profiles across development stages, shedding light on the interplay between economic growth and environmental sustainability. At the cross-country level, we analyse how the changing geography of production, and the ensuing sectoral specialisation, impacts global emissions. The relocation of low-tech and natural resources-based productions to developing countries via GVCs has jointly amplified worldwide emissions and reinforced patterns of industrial and ecological downgrading for developing nations. Implications of our findings entail the coupling of environmental, trade and industrial policies.
