| Abstract |
Busan, the second-largest city in South Korea, is currently undergoing a population decline. Traditional studies often rely on population as a
single indicator to evaluate urban shrinkage, yet this phenomenon is inherently multi-dimensional. Accordingly, this study examines the 16
basic local governments under Busan Metropolitan City and establishes a comprehensive evaluation index system across three dimensions:
population, economy, and space. The entropy method is applied to dynamically assign weights to each dimension, and local governments are
ranked in stages. Based on the changes in rankings of each unit, four types of urban shrinkage are identified: continuous shrinkage,
continuous expansion, mitigated shrinkage, and intensified shrinkage. From the distribution of these types, Busan demonstrates distinct
characteristics of East Asian urban shrinkage, namely the coexistence of growth and decline. Specifically, except for Gangseo-gu and
Gijang-gun, all other local governments exhibit varying forms of shrinkage. By analyzing the features of each type across the three
dimensions and examining representative cases, this study proposes targeted urban development strategies to support local governments in
formulating effective policy responses. |
