This study analyzes the effects of spatial characteristics on convenience stores in Seoul on the premise that they should affect the location of convenience stores. In the analysis, the entire area of Seoul is divided into 400m × 400m grids, first of all. In the next step, the spatial sampling technique is used to obtain a grid separation of 1,600m, which is the distance that the Moran’s I measure is significantly lowered. This study employs negative binomial regression to analyze the derived data. The dependent variable is number of convenience stores and locational characteristics of the grids are the independent variables in the analysis. The analysis finds that almost all the independent variables do not have significant relations with the dependent variable except the number of different businesses. The analysis results are judged to imply the saturation and poor location of convenience stores in Seoul due to the increase of small businesses
