中部地区省际产品贸易流量估算与空间分析

Inter-provincial Trade Flow Estimation for Central China

近年来,中部各省的国内和国际贸易量逐步增大,市场一体化程度有所提高。从空间流向上看,省际贸易具有明显的沿海指向,特别是制成品贸易,主要集中于临近的沿海经济核心区。中部各省之间贸易联系松散,一方面是由于受到东部沿海经济核心区强大的辐射和吸引作用,另一方面也是地区内贸易成本偏高、省际产业关联度低和产品结构趋同所致。消除地区间各种有形、无形的贸易壁垒,降低贸易成本,促进空间一体化市场的形成,是加强中部省际贸易联系的关键。

In recent years, six provinces within central China have been more and more involved in do- mestic interregional trade as well as international trade, which indicates that the overall market integration has been largely improved. Most inter-provincial trade flows are evidently coast-oriented, especially in terms of manufacturing products which almost entirely confine to the coastal core areas nearby. In contrast, those central provinces have rather weak trade relations with each other because of the great economic impact of east coastal core area; and on the other side, high cost in intra-regional trade, weak affiliations in productive system and very similar industrial structure. Therefore, more efforts need to be made by both central and local governments to eliminate those existing tangible or intangible trade obstacles and vigorously depress the trade cost so as to promote domestic market integration and inter-provincial trade within central China.
