Abstract: This paper analyses embodied carbon flows across the Beijing-Tianjin-Hebei region using an environmentally extended multi-regional input-output model coupled with structural path analysis. By tracking CO₂ emissions across seven aggregate sectors during 2017-2020, this study reveals a pronounced production-consumption asymmetry: production-based emissions increased by 153.2 Mt CO₂ while consumption-based emissions decreased by 75.5 Mt, with Hebei identified as the principal net carbon exporter. Traditional heavy industry accounts for over 50% of embodied transfers, and approximately two-thirds of emissions originate in first-stage supply chains. An inter-regional shared accountability framework for coordinated emission reduction is proposed.

Keywords: embodied carbon; multi-regional input-output model; structural path analysis; SPA; supply chain emissions; regional climate governance.
