The Differentiative Effects of Spatial Heterogeneous Characteristics on Retail Sales

Retail trade area is a space for carrying out economic activities and is various depending on local characteristics in a city. The purpose of this study is to investigate the differentiative effects of spatial heterogeneous characteristics on the retail sales using a geographically weighted regression model in Seoul. The results showed that such factors as residential population, unit price of public housing per square meter, building coverage rate and bus stop have local-scale different effects on retail sales depending on the heterogeneity of the commercial space. For example, the number of resident population is an important factor for increasing retail sales in residential areas located in the outskirts of downtown area, whereas it is reversed in location near Han river. The results of the study are summarized in two. First, it provides a clue of spatial heterogeneity that the regression coefficients of the same variables are different in the previous studies. Second, it is confirmed that the difference in the area of Seoul has a different effect on the retail sales. The results of this study suggest that the hardware and software planning of the commercial area should be applied variously in accordance with local functions and characteristics.
