Abstract:

China is being at the stage of rapid urbanization. Based on the fifth census data, this paper analyzes the migration structure of China in different administrative and scale cities in the 1990s. The result shows that it is the prefecture cities that plays important role in the Chinese population migration in the 1990s, in which the big cities, especially the mega-cities, take a more significant position. It is also found that there are differences in the migration scale between county-level cities. The average migration scale of county-level city in East China is more than in West and Middle China. For the prefecture and above level cities is more important in the process of China′s urbanization at present and in the future, this article further examines the patial distribution pattern of inner-provincial and inter-provincial migration. It is showed that there are three ladder-like levels for prefecture cities in the spatial distribution pattern of inter-provincial migration: the first level includes the Zhujiang River Delta agglomeration, Changjiang River Delta city group, west bank cities, Beijing-Tianjin-Henan city agglomeration, the core cities of Liaodong Peninsula and a few of provincial capitals in middle-west area. The second level includes most of provincial capitals in middle-west area: Shandong Peninsula urban agglomeration and other eastern cities which are close to Beijing-Tianjin-Henan area, Changjiang River and Zhujiang River. The third level includes other provincial cities of middle west area and other cities which are far away from the core cities of three metropolises in the eastern area. Besides, the circle structure is obvious in the southeast coastal area, while the peak structure is more evident in the mid-west area. With regard to the spatial distribution pattern of inner-provincial migration, it shows that there are great similarities among prefecture-level in population spatial distribution pattern. The first gathering cities are each provincial capital cities. The ESDA technology is used to study the spatial distribution features of migration in cities in China. The result shows strong concentration for spatial distribution. The Zhujiang River Delta agglomeration, Changjiang River Delta city group are the main gather cities in both of inner and inter provincial migration. Furthermore, the migration gathering city range in Zhujiang River Delta area is larger than the Changjiang River Delta. On the contrary, the cities with small migration scales are located in agricultural provinces such as Anhui, Henan, and Sichuan, etc .
