A measure of trade centre position

The present paper focuses on market area delimitation as a measure of trade centre position. Because of the inadequacy of existing methods to locate the existence and the level of store competition from a spatial perspective, our aim has been to develop a method which allows us to solve this problem. This method enables us to make an analysis of a store’s position in the region with regard to its competitors, both from a spatial perspective and from the perspective of customer type classification. The model is implemented by application to a set of retail stores in the city of Murcia for sales of fish and sea products.
