台湾都会区人口空间变动模式及其原因探析——基于区域人口密度函数的分析

摘要

通过构造区域人口密度函数，分析了台湾地区6个主要都会区近30年的人口空间变动模式。分析结果显示，台湾中小都会区逐步取代大都会区成为吸引外来人口的新兴区域；而且，台北等大都会区城市中心人口增长已陷于停滞，并出现了郊区化现象，而中小都会区仍处于人口向都会区及其中心集聚态势。这样的人口空间变动模式主要与城市的集聚经济及大城市的规模不经济密切相关。%Based on the regional density function, this paper studies the spatial change modes of population in six major metropolitan areas in Taiwan during recent three decades years. The results show that medium and small metropolitan areas of Taiwan have been gradually replacing the large metropolitan areas as new regions to attract immigration. In metropolitan areas, population growth in urban centers stopped and suburbanization emerged, while population began to concentrate in smaller urban areas as well as their downtown regions. This paper argues that such spatial change modes of population are closely related to the agglomeration economies in urban region and the agglomeration diseconomies in big metropolitan areas.
