This study presents an integrated analysis of urban centrality by bridging Central Place Theory (CPT) and Central Flow Theory (CFT) through a node–place perspective, with particular attention to the distinction between morphological and functional polycentricity. Focussing on 424 administrative districts (dong) in Seoul, this study computes potential accessibility from the CPT perspective and betweenness centrality from the CFT perspective using origin–destination (OD) mobility data. Based on these indicators, spatial centrality hierarchies are reclassified. The results reveal that approximately 25% of districts display a mismatch between the CPT- and CFT-based hierarchies, indicating a divergence between morphological and functional centrality structures. Notably, some traditional city centres, designated as core areas in planning documents, exhibit low levels of CFT centrality due to weak actual activity flows. In contrast, certain employment hubs and transfer nodes demonstrate higher CFT centrality than CPT centrality, effectively functioning as de facto activity centres. This dual spatial structure underscores the need for policy realignment and the functional reassessment of urban centres. By linking CPT- and CFT-based approaches, the study conceptualises ‘centrality disparity’ as a form of node–place mismatch and offers an empirical framework for diagnosing the multidimensional structure of urban space. The findings contribute to refining central place planning, informing strategies for functional restructuring, and guiding broader urban policy development.

This study investigates the relationship between commercial business continuity and regional characteristics, specifically, agglomeration externalities, in Seoul, South Korea, while accounting for random effects. Key findings reveal that, first, specialized retail areas experience lower closure probabilities. Second, increased related diversity increases closure probabilities, whereas higher unrelated diversity reduces them, illustrating the impact of diversity on continuity. Third, when comparing the agglomeration externalities of retail areas and their surroundings, higher unrelated diversity in the surrounding areas increases the probability of closure. Fourth, commercial development in surrounding areas, rather than within retail areas, enhances overall functionality and reduces closure probability. These results examine the positive and negative effects of agglomeration externalities on commercial businesses in Seoul, South Korea, presenting findings that specifically reflect the characteristics of the surrounding areas. In the context of future sustainable urban management, retail area management should be based on a macroscopic perspective that includes surrounding areas.

본 연구는 주택이외 거처 유형별 거주가구의 공공임대주택 입주 의사에 미치는 영향요인의 차이를 실증 분석하였다. 연구의 범위는 2017년 수도권 소재 판잣집ㆍ비닐하우스 그리고 고시원ㆍ고시텔에 거주하는 가구이다. 실증분석에 활용한 자료는 ‘주택이외 거처의 주거실태조사’ 자료이고, 실증분석 방법론으로는 χ²-검정과 t-검정을 통한 거처 유형별 거주가구의 특성 확인 그리고 이항 로지스틱 회귀분석 모형을 활용하였다. 주요 분석결과는 다음과 같다. 첫째, 주택이외 거처 거주가구의 공공임대주택 입주 의사에 영향을 미치는 요인은 가구구성, 경제ㆍ사회, 거주여건, 물리적, 제도적 특성 등 다양하였다. 둘째, 판잣집ㆍ비닐하우스 그리고 고시원ㆍ고시텔로 구분한 주택이외 거처 유형별 거주가구의 특성에 차이가 있었다. 셋째, 판잣집ㆍ비닐하우스 그리고 고시원ㆍ고시텔 이용 가구 집단 간 공공임대주택 입주 의사의 영향요인에 차이가 있었다. 판잣집ㆍ비닐하우스 거주가구는 해당 거처를 장기간 이용한 60세 이상 가구의 공공임대주택에 대한 인식 전환이 필요하며, 고시원ㆍ고시텔 거주가구에 대해서는 수요자 맞춤형으로 양질의 저렴한 공공임대주택을 공급함과 동시에 적극적인 관련 정보의 제공이 요구된다.
