本稿は、東京都町田市の横浜線旧原町田駅周辺の中心市街地で、行われた市街地再開発事業等のケーススタデイを通じ、その再開発構想・計画及びその実施過程をあとづけ、これらを規定した諸条件を明らかにしようと試みたものである。特に、この事業を通じ実現された諸権利・諸利益の空間的再編成の意義を考察することにより、商業・業務及び公共スペースの空間的な構成の特徴点を明らかにする。また、事業権利者及び関係者の当該再開発事業に対する立場、果たした役割等を市長との関係を中心に再構成しこれを位置づけ、その分析・評価を試みる。これらにより、この再開発をめぐる政治過程を再構成しつつ、横浜線及び小田急線の両駅の統合、商業中核の形成及びタウンセンターの整備といった事業計画との関連において、市街地再開発の意義を考察し、町田市の繁栄の要因を解明したものである。, In this paper, the authors describe the conception, planning and implementation of the urban redevelopment project, and specify the conditions that shaped these processes. The description involves case studies of this project and related ones in the central business district of Machida City. Machida, a thriving commercial district, is one of Tokyo's suburban cities(became a city in 1958), and has a population of about 360 thousand. This redevelopment project involved the moving of Haramachida Station (JR Yokohama Line) closer to Machida Station (Odakyu Line). The two stations were 650 meters apart, creating great inconvenience for people wishing to transfer from one line to the other. Shops around Haramachida Station strongly opposed the plan. This opposition developed into a major battle between local stores, politicians and big businesses wanting to establish department stores and other large commercial facilities. The authors place particular emphasis on clarifying the characteristics of the spatial arrangement of commercial and public spaces, by analyzing the meaning of spatial rearrangement of rights and interests created through the development projects. The authors also analyze and evaluate the positions and roles of titleholders and other interested parties by focusing on their relationship with the city mayor. To show clear reasons for the prosperity in Machida City, the authors attempt to describe the political process of the redevelopment, the meaning of urban redevelopment in relation to the redevelopment plans, the formation of ac ore commercial district, and the improvement of the town center.
