Outline of Final Research Achievements

Amount of international trade increases year by year and consequently gigantic economic network has been emerged. In the near future, new economic community will be established and international trade will be more active. This economic globalization will make interdependent relationship stronger.
This study aimed to study the interdependent relationship in global society using methodologies of data science, network science, and computational science. Evidences of structural change of economic community in crisis periods, synchronization of international business cycle were obtained. Furthermore, risk propagation from a specific country toward the rest of the world was successfully modeled.
