Spatial Structures of Planning Areas within Prefectures Viewed from the Correspondence of Them to Urban Systems

研究结果包括三篇论文。第一篇论文论述了区域城镇体系与县辖区之间的关系。从城市间迁移人口分析，中小城市除与大都市周边的地市有密切联系外，大多与本地市的城市有密切联系。因此，可以说，日本是一个以都道府县为中心的区域城市体系高度发达的国家。然后，以氏族时代的地域和当今日本的地理位置为特征，分析了区域城市体系的等级结构。第二章考察了从枪制到现在的中间行政区的发展过程。将这些中间行政区与面积更大的市辖区和/或二级医疗保健区进行比较发现，后者的面积一般比前者大，与中间行政区的关系也更密切。因此，二级医疗保健区似乎难以发挥作为医疗保健规划区的重要作用。在第三篇论文中，我们通过测量中心职能及其通勤数据，建立了3000名中心职能工作人员的中心城市的城市支流区，并考虑了它们与更广泛的城市范围之间的关系。因此，我们认识到各种类型的关系。具有稳定的区域城镇体系特征的地市之间往往联系紧密。

The results studied consist of three papers. The first paper deals with the relations between regional urban systems and prefectural territories. Analyzing the migration population among cities middle- and small-size cities mostly have close connections with cities in their own prefectures, except for the surrounding prefectures of metropolises. Thus, we can safely say that Japan is a country with regional urban systems highly developed in the frame of prefectures. And then, the hierarchical structures of regional urban systems are characterized by territories in clan age and the geographical locations of the present Japan. In the second paper we considered the development process of intermediate administrative areas from gun-system to the present system. The comparison between these intermediate administrative areas and wider-area municipal spheres and/or secondary medical care regions revealed that the latter has generally larger areas and relates closer to intermediate administrative areas than the former. Therefore, it seems to be difficult for secondary medical care regions to play an important role as planning regions of medical care. In the third paper we set up urban tributary areas of central cities with 3000 workers of central functions by measuring central functions and their commuting data and consider the relationship between them and wider-area municipal spheres. As a result we recognized various types of the relationships. Prefectures with a stable feature of regional urban system tend to closely correspond each other.
