| Abstract |
In response to intensifying heatwaves, this study evaluates the spatial mismatch between Seoul’s heat-vulnerable elderly population and their pedestrian access to three facility types: welfare-based, public-based, and private-partnership. Across 425 administrative districts, we assessed vulnerability using Principal Component Analysis (PCA) and accessibility through network analysis. We then examined the spatial relationship between these two factors using Bivariate LISA and the Spatial Error Model (SEM). The analysis revealed a clear spatial mismatch, with elderly heat vulnerability concentrated in the specific regions, while facility accessibility showed different spatial patterns. Notably, for public and private-partnership facilities, “High-Low” clusters areas with high vulnerability but low accessibility were widespread in these outlying districts. The study also found distinct locational determinants for each facility type: ‘residential communities’ for welfare-based, ‘high-density, low-income residential areas’ for public-based, and ‘commercial/business districts’ for private-partnership facilities. Thus, this research empirically demonstrates the need for a strategic supply of facilities based on regional vulnerability and facility type logic, rather than a simple quantitative expansion. |
