| Outline of Final Research Achievements |
The project aims at developing a methodology for consistent assessment of economic losses through the entire process from occurrence of a disaster to the post-disaster recovery. Specifically, we developed a model to quantify the relationship between external forces such as earthquake ground motion and inundation depth, lifeline availability and the remaining operation capacity of the industry, and verified the effectiveness of the methodology through application to the Great East Japan Earthquake. Critical components of the methodology are developed using cooperate questionnaire survey results conducted after the Great East Japan Earthquake and large-scale inter-company transaction data. The results of the project contributes to elucidate the economic recovery process associated with a large-scale disaster.

| Academic Significance and Societal Importance of the Research Achievements |
サプライチェーンの寸断を含む災害の経済影響を計量化するための分析の方法論が示された。この方法を用いれば、災害発生直後に、即時的に、影響を直接受けた地域の産業からの財・サービスの供給の変化や、サプライチェーンの寸断などによって直接被災していない地域における経済活動の停滞を予測できるようになる。この結果を用いれば、災害直後により適切な対応策を実施することを可能とする。
