中文摘要：

我国的经济社会发展伴随着大规模人口流动，人口流动既大幅度提升了城镇化水平，也在很大程度上塑造了城镇体系结构。在这一背景下，对我国的城镇化研究不能因循西方的既有理论和经验。文章以实证数据为基础，从城镇体系和区域发展两个方面，考察人口流动对于我国城镇化的作用。研究发现：①流动人口在各类城镇中的分布并不是均匀的，也不仅是指向大城市，而是大致向“首末两端”集聚；②在大规模人口流动的作用下，主要流入地和流出地的城镇体系发展并没有进入相同的发展阶段，而是进一步展现出显著的“对偶性差异”；③迄今的人口流动未能将我国的城镇体系推向一个合理分工的城镇职能结构体系，而是形成了一个各个规模等级的城市的就业结构趋同的格局。这些特征的背后是我国特定的社会经济发展条件和动力机制，这隐含着对人口流动的新古典主义理论分析的修正；在应用层面，可引申至对我国城镇化发展路径的认识及城镇发展的分类治理策略探讨。

英文摘要：

Accompanying China＇s great socio-economic development, the massive intemal migration not only augmented the urbanization level, but also reshaped the national urban system. Counting un-institutional and temporary migrants as urban population, the characteristics of China＇s urbanization are found to deviate from the western theories and empirical realities. Using census data, this paper in- vestigates how China＇s urbanization has been re-moulded by massive internal mi- gration in terms of urban system and regional disparities. The results reveal that, first, migrants are not evenly distributed in different types of cites, or concentrate in large cities only, but prefer to settle in both ends of the urban system; second, the major migrant-sending and-receiving areas are found to show paired dispari- ties, rather than converge in terms of economic development and disparities in ur- ban systems. Third, the urban system failes to form a reasonable division of ur- ban function structure, while the employment pattern of the different type of cit- ~es tend to converge. The main driving force underpins these characteristics is the unique socio-economic development setting, which may lead to the revision of neo-classical hypothesis regarding population migration. Finally, we further discuss China＇s urbanization path and the governance strategies of different cities.
