The distance to the CBD is also an important determinant as one of the location-specific
factors. In the model, the introduction of the variable is to examine both how the distance to
the CBD affects the location selection and whether there is a decentralization trend of warehouses.
The Istanbul metropolitan area has a multi-central structure. Although the traditional
CBD (Beyog˘lu, Emino¨nu¨) has lost their importance over time, it has still the biggest share in
the number of warehouses in the central districts (Table 1). Therefore, to test the variable, the
distance to the traditional CBDs (Beyog˘lu, Emino¨nu¨) is used. The explanatory variable is
Traditional CBD in the model (Table 2). High rents and scarcity of vacant areas are features
of central districts. This feature is valid for the traditional CBDs. Therefore, the variable is
expected to have a negative “2” effect on the location selection.
