Abstract：In recent years,six provinces within central China have been more and more involved in domestic 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.
