Outline of Final Research Achievements

This project conducted theoretical and empirical analyses of how firms and households change, recover, and grow in the aftermath of natural disasters from the perspective of international trade and spatial economics. We conducted a econometric analysis by generating micro data on firms and households and damage data from natural disasters. Resilience and disaster prevention are important from the perspective of growth. Furthermore, this project was also conducted on infectious disease countermeasures and economic activities under a new type of coronavirus infection. Telework facilitates work from home and deterrence of infectious diseases through telework from the viewpoints of resilience and disaster prevention. We conducted an original survey of workers and analyzed the progress of the digital economy and infectious disease countermeasures.

Academic Significance and Societal Importance of the Research Achievements

自然災害による経済的損失は大きく試算は多く存在するが、個々の企業や家計の行動は十分分かっていない。本研究ではミクロ的な視点から、どのような企業や家計がどう被害を受け、その後復興していくのかを明らかにし、どう減災できるのか、どう復興までのスピードを高めるか、について都市、産業集積や地域経済の視点から日本経済の様々な過去の災害をテーマに理論・実証研究を行った。一連の研究により、自然災害によるダメージの度合いと企業規模や企業行動(国際化など)、取り巻く地域経済(地域金融など)との関係が明らかになった。
