Critical transmission paths and nodes of carbon emissions in electricity supply chain

As the largest contributor to production-based emissions, electricity generation sector has led huge carbon emission transmissions. This is first attempt explore latest features of transmissions from final domestic consumption China in 2002–2015, combining MRIO-based Structural Path Analysis and transmission-based method. Results show that: (1) Although inter-provincial are increasing significantly, within intra-provincial trading dominated. (2) 30 provinces classified into two types, i.e., centers production centers. Both transmission paths grid-level agglomeration provincial heterogeneity. The inflow mainly sourced Eastern South China, while outflow for caused by Central Guangdong Jiangsu. Inter-provincial linkages intensified perform feature territorial propinquity. (3) intra-grid inter-grid nodes an trend “electricity < intermediate sectors consumption”. These include manufacture sectors, energy-intensive service sector. paper provides policy implications on promoting low-carbon cooperation across managing along supply chain. • Newly compiled MRIO table, SPA approach TBB accounting combined. Emission change consumer explored. decomposed Transmission types Key manufacture,
