On June 1, the National Assembly of South Korea passed a special law for the establishment of a new unified metropolitan city combining Jeonnam and Gwangju, leading to the election of the city mayor in local elections next June. This administrative integration reflects a growing consensus among various regions, including Chungnam-Daejeon and Daegu-Gyeongbuk, aimed at bridging the gap between the capital region and non-capital areas. While the integration is seen as a unique opportunity for effective governance and regional development, the potential for failure and unintended consequences necessitates thoughtful evaluation of the requirements for success in such integrations.

A significant concern raised in the discussion of these metropolitan integrations is the risk of undermining democratic autonomy and the principle of supplementary governance. With larger administrative units, there is skepticism regarding their ability to address local issues effectively. The case of Changwon, which integrated the cities of Masan, Changwon, and Jinhae, illustrates how such integrations can lead to feelings of neglect in surrounding regions, particularly when resources and administrative focus are concentrated in a central area, exacerbating existing disparities despite investment efforts.

To ensure successful metropolitan administrative integration, a more proactive approach from the government towards regional balanced development is essential. Enhancing regional equity cannot solely rely on administrative unification, which may inadvertently intensify competition between regions for resources and investment. This could result in regulatory relaxations in crucial areas such as labor and healthcare without achieving the intended objective of balanced regional growth. Thus, ensuring equitable competition between regions, alongside appropriate governmental support, is crucial to achieving harmonious development throughout the country.
