세종시 인구이동의 시공간적 특성과 권역별 영향 요인 분석: 중력모형을 활용한 상호작용 효과를 중심으로

초록

This study analyzes the spatial and temporal dynamics of population migration following the establishment of Sejong City and seeks to derive policy implications for the Multifunctional Administrative City Development project. Based on the migration data from 2013 to 2020 at the district level across the country, the analysis was conducted through a gravity model incorporating Sejong City’s characteristic variables, along with interaction terms accounting for temporal and regional variations. The findings indicate that population inflows to Sejong City have steadily increased, with housing supply serving as a major factor influencing migration throughout the study period, particularly from the Daejeon and Chungcheong regions. Conversely, the impact of public institution relocation, initially marginal, has become more pronounced, particularly emerging as a significant driver of population inflows from the Seoul metropolitan area. These results suggest that the Multifunctional Administrative City Development project should extend its focus beyond housing supply, emphasizing the enhancement of economic incentives, such as public institution relocation and job creation. Furthermore, the study underscores the need for a strategic approach to foster cooperative development between Sejong City and the Daejeon-Chungcheong regions.
