Outline of Final Research Achievements

This study aimed to understand the structural properties of inter-firm supply relationships, from perspectives of both industrial resilience and individual firms' surviving strategies. Starting from collecting large-scale empirical data capturing complex inter-firm trade networks, the project was proceeded by complex network analysis of the big-data, and application of the method developed in the study of international trade. The results elucidated the common and different features of inter-firm and inter-national trade relationships. Furthermore, it was found that the industrial network structure reflects the diversification of firms' resource limits and their portfolio building strategies. Our analysis also identified the characteristics of portfolios of firms that bankrupted, suggesting how firms should build their portfolios for survival.
