湖北省县域迁入人口的空间格局及影响因素

利用第五次和第六次人口普查分县资料,分析湖北省县际迁入人口的空间格局及变化,探讨迁入人口空间格局形成的内生机制。研究发现,2000年以来迁入人口向地级市市辖区以及与其邻接的地区集中,县际分布差异扩大,但是空间集聚程度下降,以武汉市为中心的"中心-外围"空间格局日益明显。在地区名义工资和社会发展水平等其他条件不变的情况下,差异化工业制成品和服务业产品的可获得性是人口迁入的重要原因。而推进区域一体化可以提高本地对差异化产品的可获得性,吸引人口迁入,进而诱发人口与产业向本地同向集聚。

SPATIAL DISTRIBUTION OF IMMIGRANTS AT COUNTY LEVEL AND ITS DETERMINING MECHANISM IN HUBEI PROVINCE

Migration is an endogenous result and also an endogenous factor of regional socio-economic development. Using the county-level data of the fifth and sixth census, the spatial-temporal pattern of the distribution of inter-county immigrants in Hubei province is analyzed, and the endogenous mechanism is explored based on the New Economic Geography framework. It shows that immigrants has being concentrated to the city municipal districts and their adjacent regions since 2000, which enlarged the gap but decreased the degree of agglomeration of distribution of immigrants between counties in Hubei province. It is the availability of differential manufacturing and service products that determines the immigration. A region having more firms and adjacent to the regions that have more firms will have higher availability of differential products, which would have more strong pulling power on migrants. Moreover, regional integration is beneficial to enhance local availabilities of differential products and thus to attract immigrants, which would induce the coagglomeration of population and industries.
