Outline of Final Research Achievements

The authors conducted a theoretical study of economic agglomeration that has been dealt with independently in Economic Geography, Spatial Economics, and Geography. In this research project, we have proposed a core-periphery spatial agglomeration pattern as a synthesis of our study. We have developed a theory for the formation of the core-periphery pattern from a complete agglomeration to a single place and conducted a simulation of the core-periphery pattern by an economic geography model. The results of this research project are presented as several research papers in Int. Journal of Bifurcation and Chaos, Networks and Spatial Economics.

Academic Significance and Societal Importance of the Research Achievements

申請者らは，経済地理学・空間経済学・地理学で個別に取り扱われてきた，人口・経済の集積現象に関する基礎研究を進めた結果，本申請では，上記の3つの研究分野を横断する視点として核周辺型の集積パターンを提案できた。本研究の成果は，Int. Journal of Bifurcation and Chaos, Networks and Spatial Economics という世界的な専門誌に掲載されており，学術的な意義が高い。
