This paper makes numerical simulation based on the expanded core periphery theory model from the new economic geography angle, and introduces the resource endowments coefficient as a parameter, in order to identify the key factors of the industrial transfer slowdown. The conclusion shows that elements of resource endowments, transportation costs and labor costs are still the important factors that affect the industrial transfer. The eastern part of China manufacturing industry has not reached the endogenously critical point of industrial transfer yet. Finally, it gives some reasonable suggestions for the industrial transfer.
