摘要：

运用第五次人口普查数据, 利用中心-外围模式对长江三角洲都市连绵区城市之间人口迁移进行考察, 可以发现人口向中心地区---上海集聚是该区域的主要发展趋势; 在外围地区人口空间流动上存在南北翼之间的差异; 在各城市内部还存在着强烈的人口城市化过程。在此背景下, 该都市连绵区各城市应接轨大上海, 谋求错位发展; 实施统筹发展的加速城市化战略; 加强南、北翼之间的合作; 充分利用中心的人力资本优势来实现长江三角洲的一体化发展。

Abstract:

Based on the fifth census, we use the core-periphery model to inspect the migration among cities in the Yangtze Delta megalopolis. It is known that dynamics of agglomeration and diffusion in the megalopolis manipulate developments of cities. The strength of agglomeration is a major force in the megalopolis, and the pursuit for economic benefits is a basic reason for population clustering. Meanwhile, the inter-city dispersion is mainly a non-class diffusion. Also, dynamics of population in the periphery differ between north and south. The north in the Yangtze Delta has a denser interaction with the core than the south. But when applying the gravitation model to analyze the spatial interaction, we find that the decay of distance friction between south and core is smaller than the north, which indicates that the relation between south and core is increasing. In intra-cities there is a dense population flow, and the population urbanization and the migration between blocs are two main trends. Some policies should be adjusted to fit an integral development in the megalopolis.

Key words: megalopolis, migration, core-periphery
