Outline of Final Research Achievements

This study is about the Shibuya redevelopment, which is said to be a "once in a century" event. The results are as follows:Firstly, through literature surveys and interviews with relevant parties, the background and vision of the Shibuya redevelopment was analyzed. The study revealed a process in which local government, business, and local communities cooperated to solve local issues while skillfully utilizing national policies, taking advantage of intensifying global competition between cities and domestic urban regeneration policies.
Secondly, the changes in the local community were analyzed using the example of a new festival that utilized the new public space created by the redevelopment. Initially, the festival was carried out mainly by the local government and redevelopment business operators, but gradually the actual initiative shifted to local community development organizations, and the actors became more diverse, revealing a transformation in the local community.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的な意義は、学際的な視点で渋谷再開発を分析した点にある。日本国内については、戦後の首都圏政策や交通政策、バブル経済崩壊後の政府の都市再生政策、ならびに渋谷区のまちづくりなどを複合的に分析し、なぜ今、渋谷再開発が可能になったのかを明らかにした。そして、国内の文脈だけでなく、その背景にあるグローバルな環境の影響についても、世界都市論やクリエイティブ都市論といった都市研究の知見に基づいて考察した。また、「100年に一度」と称される渋谷再開発は社会的な関心も高いことから、その背景や経緯、目標についてまとめた点に社会的な意義も認められよう。
