| Abstract |
This study analyzed network characteristics to understand population mobility in Gyeongsangnam-do before and after COVID-19. Mobile travel
data from September 2019 and 2020 were compared to analyze daily movement during the same period. Data from 22 cities and counties in
Gyeongsangnam-do and 16 cities and provinces nationwide were analyzed using network statistics and block modeling techniques. The
analysis showed that movements were simplified into five blocks after COVID-19, compared with six blocks before, indicating a simpler
movement pattern. Urban migration may continue regardless of surrounding areas, post-COVID-19. When a metro area's population surpasses
half of the total population, fundamental measures are needed to address population concentration. Emphasize regional hub cities in
development policies. This study is significant because it demonstrates changes in population movement in Gyeongsangnam-do before and
after COVID-19 using centrality and movement pattern analysis. To fully understand population movement in Gyeongsangnam-do, analyze data
on freight, information, and capital movement, as well as distance between regions, in conjunction with the study results. Address these
limitations in future research. |
