An Economic Geographical Study on Agglomeration Effects and Technological Linkage in the Science-based Industires

研究成果の概要 (和文) : 本研究では，技術・人的連関の観点からサイエンス型産業の集積効果を検討することを通じて，産業立地の再編と都市経済・産業集積との関連性を考察した．その要点は，第1に，製造業においては東京大都市圏を中核地域とする地域間所得移転の動きが弱化しており、従来型の産業構造にもとづく階層的な地域間関係が変化していることが傍証された．第2に，過去30年間において，日本の加工組立型製造業の空洞化によって企業内地域間分業に変化が生じ，都市システムの変容やグローバルでの立地調整が進展した．研究成果の概要 (英文) : The purpose of this project is to investigate the agglomeration effects of science-based industries in the recent urban metropolitan area from the viewpoints of technological linkage, and also to focus on the relationship between industrial locational changes and urban economies. The following points were made clear by this study. First, the Tokyo metropolitan area is one of the most economically developed cities and manufacturing industries play a central part in the Tokyo’s industrial structure. Inter-regional income transfer analysis among the Tokyo metropolitan area and other regions reveals that the centrality of Tokyo in the manufacturing industries has weakened since the late 1990s. Second, during the last three decade, the hollowing out of Japanese manufacturing industries has brought about the structural transformation of corporate inter-regional divisions of labor in Japan, and it has also changed and improved urban system and locational adjustment in Asia
