This paper deals with structural approaches to regional/local polarization in Korean society and systems thinking, especially the impact of the post-COVID19 era. Toward this purpose, this paper intends to contribute to the practical policy direction by deriving CLDs (Causal Loops Diagrams) on regional/local polarization through reviews of various literature on related topics, reflecting the effects of the post-COVID19 era in this system structure.
Based on the simple and basic structure of the population emigration to the SMR (Seoul Metropolitan Area), focusing on regional/local jobs and settlement conditions, structural inference is conducted on the dynamic structure and policy response effects of the post-COVID19 era through the distinction between existing and new industries. In conclusion, this paper emphasizes that the influence of the era causes accelerating effects through a series of reinforcing causal loops in the existing regional/local polarization structure and needs appropriate policy responses to stabilize them.
