Centralités urbaines et concentrations de commerces

Abstract : The urban phenomenon is often defined as a concentration of activities. One of these activities, one of these functions may reflect all the urban dynamic, or even a motor of urban regeneration. the commercial function, in particular retail and services, could play this role within the city. The repartition of the retail function into the urban space answers to crystallization logics, which are interestings to study to highliht the places which have more centrality in the city. The author calls "shops concentrations" these privilegied places. Could such places be an important element to be taken into account for the urban centralities approach? This research suggests to study this using three "sample agglomerations". The author chooses three different French urban areas of different weight (from 200,000 inhabitants to more than a million inhabitants), which also have a different urban configuration : Lille-Roubaix-Tourcoing, Nancy and Rheims. The approach of the retail machinery of each of these urban areas enables to have a better illustration of a theoretical approach.
For this purpose, the research offers an estimate of the commercial centrality. This presupposes a good evaluation of both quantitative and qualitative elements. It is also necessary to consider the theoretical and practical difficulties of the spreading of the retail potential. The aim is to know which place we can give to retail urbanism in urban planning. Is retail crystallization a good urban revitalizing tool ? The question is to know which locations modalities and which situation criteria must be respected by shops concentrations fot then to play a coherent part in a global planning policy. In fact - as in all planning processes - it is necessary to examine carefully the forms and the context as much as the injected function.
