Description
Summary:This study sought to assess disaster resilience in Korean metropolitan cities and explore the factors influencing disaster management in these cities. Statistical data from 17 metropolitan cities and provinces in Korea spanning the years 2016 to 2020 were collected. Data envelopment analysis (DEA), a method for estimating relative efficiency using multiple input and output variables, was employed to calculate the disaster resilience scores of these cities. The results indicate higher level of disaster resilience in capital regions and large cities in Korea, with social and economic characteristics significantly influencing resilience. Moreover, the study reveals that robust infrastructure, particularly in terms of housing, strongly impacts resilience scores. The use of DEA allows for the practical evaluation of relative resilience scores without requiring weighted value calculations, making it an effective methodology for assessing city resilience.
