Abstract

The first special local government in Korea, the Busan-Ulsan-Gyeongnam Special Coalition(Bu-Ul-Gyeong megacity), has been announced in April 2022. Its urban spatial structure plan presents the four central cities - Busan, Ulsan, Changwon, and Jinju. It highlights increasing regional accessibility among central cities to make the Bu-Ul-Gyeong megacity a unionized community across regional borders. First, this study analyzed the urban spatial structure of the megacity using data from the 2019~2020 floating population. As a result, the paper observed that the central cities are different from the internal and external network of South Gyeongsang Province (SGP), and there were some underserved areas for accessing public transportation services within SGP. It implies that measures to improve linkages among areas of SGP are necessary to realize the network urban spatial structure in the BUG megacity. In this context, second, the study identified the first central areas of SGP as Changwon and Jinju based on the eigenvector centrality and flow betweenness centrality. The second central area is investigated by conducting a community analysis focusing on SGP. The four communities are presented and the second central areas are identified as Haman, Sacheon, Tongyeong, and Geochang in each community.
