Outline of Final Research Achievements

This research determined: (1) the activity potential of mutual assistance, (2) the structure of the mutual assistance network, and (3) the mutual assistance network associated with the secular change in social capital (SC) for earthquake waste management. The structure of the mutual assistance network was determined by focusing on the mutual assistance behavior conducted through the SC network of citizens. In addition, SC is a necessary factor in community resilience for recovery from disasters. The spatial characteristics of community resilience were determined by focusing on SC. The effectiveness of weak SC linkages in the metro area was shown by estimating SC networks for intra and inter communities.

Academic Significance and Societal Importance of the Research Achievements

学術的意義は、概念的に考えられてきた共助行動をSCネットワークの枠組みで整理することにより、定量的にその可能性を評価した点である。これらは、SCネットワークの類型化研究に貢献する。社会的意義は、大都市住民間の弱いSC連携の有効性を明らかにし、自然災害レジリエンスにおける弱いSC連携の活用方法を提示した点である。
