An Analysis of Factors Influencing Regional Resilience to Disaster Using the Resilience Cost Index

Natural disasters whose scale of damage exceeds the level that regional governments can afford are increasing. As such disasters have increased, the damage to local communities tends to be prolonged. Accordingly, it is important to prevent prolonged disaster damage and secure resilience to ensure quick recovery from the damage. This study analyzed the regional factors that can affect resilience to disaster, quantifying the regional resilience of each sigungu administrative district in Korea that suffered damage from natural disasters during the period 2010-2017 using the resilience cost index (RCI). We investigated the relationship between change in resilience cost index by year and changes in regional factors by year to identify the regions where industrial diversity was secured so as to reduce the exposure of each industry to disaster, budgets for social welfare were increased, and participation in volunteer activities was expanded, all of which tend to improve regional resilience.

Alliance Network Diversity and Innovation Ambidexterity: The Differential Roles of Industrial Diversity, Geographical Diversity, and Functional Diversity

Innovation ambidexterity, namely, performing exploitative and exploratory innovation simultaneously, is important for high-tech firms to achieve sustainable success. This can be achieved by building an egocentric alliance network. Research into the influence of alliance network diversity on innovation ambidexterity is seeing more attention. However, the differences among multiple alliance network diversities are unclear. Grounded on a knowledge-based view, organizational learning theory, and transaction cost theory, this study investigates in-depth the roles of geographical diversity, industrial diversity, and functional diversity of the alliance network. The empirical analysis based on panel data, including alliance data from the SDC Joint & Venture database and patent data from the Derwent Innovation Index database of 106 top high-tech firms from electronic information and biopharmaceutical industries, suggests that industrial diversity enhances firm innovation ambidexterity, geographical diversity impedes firm innovation ambidexterity, and functional diversity shows an inverted U-shaped relationship with firm innovation ambidexterity. These results provide practical suggestions about alliance network diversity configuration and innovation ambidexterity construction for high-tech firms.
