Purpose: As the numbers of opticians and opticians' shops increase and as the price competition intensifies, the competition to gain access to a large number of customers increases. In this study, the relationship between the Seoul metropolitan subway station area and distribution of opticians' shops was analyzed using a geographical information system, and the correlation with the number of daily passengers at each subway station was identified.
Methods: Locations of the subway stations and the number of passengers at each subway station were provided by the Seoul Metropolitan Government. The address books at the opticians' shops registered in 2016 with the Korean Optometric Association were used. The range of each station area was set as a circle with a radius of 0.2, 0.5, or 1 km, with a subway station at the center. The correlation between the Seoul metropolitan subway station area and the distribution of opticians' shops was analyzed using QGIS 2.10.1. The number of daily passengers at each subway station and distribution of opticians' shops located in the station area were compared.
Results: The largest number of opticians' shops within a 0.2-, 0.5-, or 1-km radius from a subway station were located in the Hoehyeon Station area, probably because of the number of wholesale shops in Namdaemun selling glasses. As the radius of the station area increased, the number of opticians' shops located in each station area tended to increase at stations with a large floating population. Eighteen stations had no optician's shop within a 2-km radius. These stations were located in areas containing farmlands or mountains or had fewer connected public transportations or relatively fewer residents. Moreover, the number of opticians' shops changed as cities developed and populations changed.
Conclusions: An analysis of the correlation between subway stations in the Seoul metropolitan subway station area and the distribution of opticians' shops using geographical information system revealed that more opticians' shops were distributed near the stations that were located in downtown areas or had a large floating population. Despite the limitation of not fully considering the overall connection among public transportations, this study could help select the locations of opticians' shops considering their overall distribution and accessibility and be useful as a basis for similar studies in the future.
