| Outline of Final Research Achievements |
After examining the structure of global inter-firm networks, we discuss the implications of global linkages at the firm level for the proliferation of ‘conflict minerals’ or dirty products through global buyer-supplier linkages. We show through community structure analysis that firms cross national borders and form communities in the same industry. There are also firms that act as bridges between these communities, so that throughout the world each firm is connected with an average of six business partners. By enhancing this feature of links between firms, it can be used as a countermeasure for risks related to conflict minerals and slave labor issues. By utilizing a simple diffusion model and empirical results for the community structure, we show numerically that regulations on the purchases conflict minerals by limited number of G8 firms belonging to some specific industries would substantially reduce their worldwide use.

| Academic Significance and Societal Importance of the Research Achievements |
我々は，アフリカや中東など遠く離れた国で起きている紛争と，自身の経済活動とは関係がない（または関係が希薄である）と思っているが，グローバル化により，実は密接に関係していることをビッグデータから実証的に示した．これにより，我々が日々の経済活動を通して気づかぬ間に紛争に加担していることを見える化し，紛争の潜在的な加害者になっていることを認識させることで紛争を身近に感じさせ，紛争解決に向けた国民と企業の規範を形成させることに寄与している．
