This study begins with the recognition that local trading areas should be approached as public goods where economic, social, cultural, and human capital converge, making physical space essential for their functioning. The purpose of this study is to propose spatial management strategies at the local level to revitalize local trading areas and establish a sustainable economic ecosystem in response to the era of population decline and low growth. To this end, the study identifies the scope and targets of spatial management for local trading areas in connection with their surrounding living areas, and suggests policy and institutional improvements for spatial management to support the revitalization of local trading areas.
