FACTORS OF HUMAN MOBILITY CHANGE IN COMMERCIAL AREAS DURING COVID-19 PANDEMIC - FOCUSING ON THE SPATIAL DISTRIBUTION OF RESIDENCE AND THE INDUSTRIAL COMPOSITION -

Abstract

 This study aims to clarify the factors of human mobility change in the commercial area during the COVID-19 pandemic. First, we employed the change patterns of human mobility based on the mobile big data in 21 cities, including government ordinance-designated cities. Second, we analyzed the change in human mobility considering the spatial relationship between the target commercial area and the origin of human mobility defined by residence information. Lastly, the factors of human mobility change were investigated considering the number of employees in each industry. The major findings are as follows. 1) The human mobility from the same or neighboring districts does not show a significant change, while the human mobility from the remote city shows a great decrease. 2) The increase of human mobility from the same or neighboring districts is prominent in the increased pattern. 3) The major metropolitan areas of Tokyo and Keihanshin show a positive relationship between the number of employees that support daily life and increased pattern, but regional urban areas do not.
