This paper investigates the spatial distribution of existing shopping malls and tries to estimate the retail potential of Istanbul. A gravity model is applied to figure out the retail potential of the seventeen districts with and without shopping centers. Disposable income of the households, distances to the existing and proposed shopping centers, and their sizes are examined. The districts are ranked with respect to their estimated retail potential and a choropleth map was used to visualize the consequences of estimated retail potential. The paper suggests that the spatial pattern of urban retail growth has experienced a centrifugal shift from central city locations to more peripheral areas. However, the results show that more central districts have higher retail potential.
