Abstract

Global value chain (GVC) changes have had an impact on economic growth and carbon dioxide (CO₂) emissions in various provinces. This study links the Chinese provincial multiregional input–output table to the world input–output table. The provinces are divided into carbon peak and nonpeak groups to explore the impact of GVC changes in relation to driving factors of provincial decoupling. The results are fourfold. (1) For peaking provinces, after reaching the peak, the GVC and domestic effects combined to promote strong decoupling. (2) Most nonpeak provinces are weakly decoupling. The hindering effects on decoupling decreased after the 2008 financial crisis. (3) For peaking provinces, the positive effect of emissions intensity has been sufficient to offset the negative effect from the final demand, but was not sufficient to offset nonpeak provinces. (4) The hindering effect of GVC production-related factors has lowered. This study proposes that nonpeak provinces improve production technology.

全球价值链变化在中国各省二氧化碳排放与经济增长脱钩中的作用

全球价值链（GVC）的变化对各省的经济增长和二氧化碳排放产生了影响。本研究将中国省际多区域投入产出表与世界投入产出表联系起来。将各省划分为碳峰组和非峰组，探讨全球价值链变化对各省脱钩驱动因素的影响。结果是四方面的。(1)对于峰值省份，在达到峰值后，全球价值链与国内效应共同促进强脱钩。(2)大多数非高峰省份弱脱钩。2008年金融危机后，脱钩的阻碍效应有所减弱。(3)对于峰值省份，排放强度的正效应足以抵消最终需求的负效应，但不足以抵消非峰值省份。(4)全球价值链生产相关因素的阻碍作用减弱。本研究提出非峰省提高生产技术。
