Outline of Final Research Achievements

This research project found that (1) although economic shocks propagate through supply chains and information networks, the negative effect can be alleviated by the diversity of networks, and (2) the diversity of networks can be promoted by social interactions, although the effect of social interactions can be opposite in some occasions, using various network data and collaborating with the University of Sydney, Hanyang University, and Arsi University. 10 papaers (of which 6 were published in international refereed journals) were published as the outcomes of the project.

Academic Significance and Societal Importance of the Research Achievements

本研究では、多層的な経済・社会ネットワークの役割についてこれまで必ずしも現実のデータを使って定量的に示されていなかった問いに対して、経済主体の異質性を考慮しつつ解答を与えたところに学術的な意義がある。また、これらの学術的な成果に基づいて、政策や企業経営に対して提言を行っており、米中の分断や経済安全保障のためにグローバル化が停滞もしくは縮小している現在、社会に対して一定の貢献があると考えられる。
