The purpose of this study is to develop the definition of disaster resilience concept and to propose its quantification concept from a social cost perspective. The employed methods are literature review and exploratory spatial data analysis. The results are as follows; First, community disaster resilience can be defined the community’s system capacity to minimize both the magnitude and duration of community system impacts after natural disasters from the perspective of community’s target system performance. Second, the critical elements for the resilient community are (1) the systematic interconnection between capitals found in communities, (2) the substitute to ensure the level of community system performance. Third, the disaster resilience quantification can be represented as a concept of resilience cost. Fourth, resilience ratio is a useful concept to understand a certain community’s ability in responding natural disasters. Fifth, high social costs are found in Seocho-gu and Dongducheon-si from a concept of disaster resilience. Sixth, TRE(Total Recovery Eefforts) minimizing strategies are required in the regions including Ansugn-si, Secho-gu, Icheon-si, Dongducheon-si, Gangnam-gu, Sungdong-gu, Gwangjin-gu, Eunpyeong-gu, Joong-go, Yangpyeong-gun. Seventh, LISA shows that Yeoju-si and the north parts of Gyeonggi-do have a homeogenous spatial relationship.
Based on the results, four policy implications are addressed. First, a sophisticated quantification method needs to be developed. Second, we need a strategy to share responsibility in dealing natural disasters with citizens. Third, we need a substitute development and management system. Fourth, Gyeonggi-do needs to adopt a resilience concept in disaster management policies and to show interest in R&D.
