The dynamic change of energy supply and demand structure within China: a perspective from the national value chain.

The complexity of the national value chain (NVC) has significantly impacted the level of energy consumption embodied in domestic trade. This paper aims to measure embodied energy and its spatial transfer between provinces and determine the dynamic change in the energy consumption supply and demand structure within China. This paper applies the multiregional input-output model (MRIO) to establish three accounting frameworks from forward-linkage, backward-linkage, and trade in value-added (TiVA) perspectives to comprehensively track energy consumption transfer along the NVC during the period 2007 to 2017.
