Abstract

With the revitalization of alley market area becoming a major goal of the urban regeneration project, an understanding on customer characteristics that affect the sales of alley market areas is needed. As spatial heterogeneity appears to exist in alley market areas, the use of GWR (Geographically Weighted Regression) is required as an alternative to OLS (Ordinary Least Squares) regression. This study analyzes effects of customer characteristics on sales of 1007 alley market areas in Seoul. Comparing R squared and AICc, results show that GWR is better than OLS regression. According to OLS regression, the ratio of female, the ratio of 40's and 50's, the number of employees, the opening rate of establishment, the density of building and the size of alley market area have positive effects on sales, while the ratio of 20's and 30's, the distance of bus stop and that of subway station have negative effects. As a result of comparing local regression coefficients of geographically weighted regression analysis, the ratio of female customers has the greatest effect on the northwestern region, followed by the southwestern region, the central region and the northeastern region. The ratio of 20's and 30's and that of 40's and 50's effect on the southeastern and northeastern regions, and then the southwestern region. It is expected that this study will help to identify marketing target for each alley market area.

도시재생사업의 활성화와 함께 주요 사업대상이 되고 있는 골목상권에 대한 사회적 관심이 커지고 있다. 골목상권 재생 방안을 마련하기 위해서는 어떤 고객이 얼마나 많이 매출을 발생시키는 지를 파악하는 것이 무엇보다 중요하다. 이에 본 연구에서는 고객특성이 골목상권 매출액에 미치는 영향을 분석하고자 한다. OLS 회귀분석 결과, 종속변수인 골목상권 매출액과 독립변수인 고객특성, 입지특성, 구조특성의 관계가 상권위치에 따라 달라지는 공간적 이질성이 확인되어 본 연구에서는 대안으로 지리가중회귀분석을 수행한다. 모형 적합도를 $R^2$과 AICc를 통해 비교한 결과, 지리가중회귀분석이 OLS 회귀분석보다 더 우수한 것으로 나타났다. OLS 회귀분석을 통해 여성고객 비율과 40-50대 고객비율, 골목상권 내 종사자수, 사업체 창업률, 건축물 밀도, 골목상권 면적이 정의 영향을 주는 반면 20-30대 고객비율, 지하철역과의 거리, 버스정류장과의 거리는 부의 영향을 주는 것으로 나타났다. 지리가중회귀분석의 국지적 회귀계수 값들을 골목상권별로 비교한 결과, 여성고객 비율은 서북권 골목상권 매출액에 가장 큰 영향을 주며 서남권과 도심권, 동북권은 그 다음으로 나타났다. 20-30대 고객비율과 40-50대 고객 비율은 동남권과 동북권 골목상권 매출액에 큰 영향을 주며 서남권은 그 다음으로 나타났다. 본 연구는 고객특성 중 성별과 연령에 한정된 분석만 수행했다는 점에서 한계를 갖지만 골목상권별로 매출액 영향 요인을 식별함으로써 상권 활성화방안 수립과 도시재생사업에 도움을 줄 수 있을 것으로 기대가 된다.
