Résumé : The originality of this article is to analyze the tendencies to the competition or the complementarity of the types of shops differentiated according to a fine nomenclature, whereas the literature is generally limited to the great groups of retail, however heterogeneous in the field of the localization. By means of a data base, locating 23, 180 commercial cells of 88 different types in Brussels, and of two methods of analysis of concentration/dispersion, the study identifies 16 retail types significantly more dispersed and 24 significantly more concentrated than the average. The factors of this differentiation, inventoried according to the literature, are re-examined in the light of these observations.
