摘要

Owing to uneven development and unbalanced resource endowments within China, ensuring reliable energy, water and food supply is a core challenge to regional socio-economic development. This study makes a first attempt to examine and compare demand-driven energy, water and arable land (E-W-L) resource outsourcings within China based on the latest multi-regional input-output model. Results show that interprovincial trade reallocated 73.4%, 33.9% and 38.1% of the national total E-W-L resource inputs in 2012, respectively. Investment was the dominant final demand category for driving energy requirements, while consumption was the leading final demand category for water and arable land requirements. Important provincial regions and critical transmission sectors for the trade of embodied E-W-L resources are identified. Substantial E-W-L resources were transferred from the central and western regions to the eastern regions. Especially, Inner Mongolia was the top interregional net exporter of embodied energy, while Jiangsu topped the net importer list. Regarding virtual water transfer, Xinjiang and Shandong were the biggest interregional net exporters and net importers, respectively, while Heilongjiang and Guangdong stood out in the net trade of embodied arable land. Owing to the impact of interprovincial trade, the resource occupancy levels of the eastern developed area were much higher than those of the northeastern, central and western areas. The imbalances in the levels of socio-economic development amongst provincial regions are mirrored by their patterns of E-W-L uses and related trade transfer. Understanding the synchronal outsourcings of E-W-L resource requirements provides important implications for targeted resource management in Chinese interprovincial supply chains.
