초록

The COVID-19 pandemic has had a significant impact on daily life in Korea. During the pandemic, spatial information on the confirmed cases provided through emergency alert texts on mobile phones played a crucial role in reducing the spread of COVID-19 by containing the floating population immediately. However, due to the concern of an invasion of privacy, the scope of spatial information on confirmed cases had been changed from the neighborhood (dong) unit to the municipal (si/gun/gu) unit, which might have reduced the efficiency of emergency text messages during the pandemic. This study explores the impact of the change in the spatial range of COVID-19 emergency alert texts on the change in the floating population and identifies differentiating impacts by gender and age. The methodology adopted in the study is a dynamic panel modeling that can control the lag effect of the dependent variable while observing the lag effect of the independent variable in the panel data. Our analysis results indicate that the immediate decrease in the floating population was more pronounced when the provision was made in the neighborhood (dong) unit rather than the municipal (si/gun/gu) unit. In addition, the study confirms that the effects could be differentiated by age and gender. Specifically, the floating population decreased significantly and immediately in the 30s rather than in the 10s and 20s. The decrease in the floating population due to the emergency alert texts was greater in men than women. In conclusion, the study found that the effect of the COVID-19 emergency alert texts could be essential and immediate in providing specific information about the location of a COVID-19 outbreak, and that this effect is differentiated by age and gender.
