Outline of Final Research Achievements

This study aimed to elucidate the mechanism of urban resilience to natural disasters and to consider proactive measures and recovery policies. In the mathematical model approach, a model based on New Economic Geography was used to clarify the impact of the degree of trade and movement freeness with other cities and the characteristics of the city on resilience. In the empirical approach, a systematic review was conducted to identify a comprehensive set of indicators that explain urban resilience. In addition, the factors influencing housing recovery were identified by analyzing data from actual disaster cases.

Academic Significance and Societal Importance of the Research Achievements

本研究成果の学術的・社会的意義は下記の2つである.
一つ目は，新経済地理学に基づくモデルによって，周辺都市のレジリエンスの変化や被災・回復状況が対象都市のレジリエンスに与える影響を評価可能にしたことである．
二つ目は，わが国では初めてレジリエンス評価指標の実証的検証を行うことによって，対象事例は限定的であるものの住宅再建に与える要因とその影響を特定したことである．
