The economic resilience of amenity cluster in the post-Covid city: the effect of relatedness on the survival of amenity shops

Amenity clusters that consist of coffee shops, restaurants, and other small businesses provide utility to urban life and jobs for city dwellers. While most small business clusters were hard hit by the restrictions imposed during the COVID-19 pandemic, others were able to adapt. What determines the economic resilience of amenity clusters? By using store-location data for Seoul during 2016-2021, we identify spatial clusters of amenities and an \textit{amenity space} to examine the effect of relatedness on the resilience of each cluster. We find that businesses are more likely to survive when located in clusters of related amenities.
