我国区际贸易及其价格传导效应研究

Regional Trade and Its Price Transmission Effects in China

本文考察我国区际贸易规模与格局的变化特征,发现我国区际贸易规模逐步扩大,区际贸易顺差和逆差分布极度不均,东部地区多为顺差,而中、西部地区多为逆差。通过考察区际产业贸易关系,对区际价格传导效应研究发现,区际贸易主要在邻近省份之间展开,远距离省际贸易相对较少;产业链上游省份的各类价格对产业链下游省份的价格传导效应较为显著;伴随区际贸易的价格传导,价格波动分配效应在各省份间开始显现。

This paper explores domestic trade between different regions in China. It presents that scale of inter-provincial trade is gradually expanding, but its distribution is extremely uneven across regions. Majority of trade surplus is in the eastern region, while central and western regions have trade deficit. It examines regional industrial linkages and price transmission effects. It shows that majority of trade is between neighbor provinces. Price transmission effects, from provinces in upstream industrial chain to ones in downstream chain, are strong while price fluctuations will cause adjustments of relative benefits of different provinces.
