Test of integration of the spatial factor in the analysis of the competition: Application made on the cafeterias of the town center of Ain el hammam[Essai d’intégration du facteur spatial dans l’analyse de la concurrence: Application faite sur les cafétérias du centre-ville de Ain el hammam]

The location of economic activities has long been marginalized in favor of other issues related to production, consumption and trade. It took a long time, before seeing a branch of the economy to have space as an object. Thus, the space economy has always tried to integrate the spatial factor in order to understand and join space to the analysis of economic phenomena such as competition. As a result, the conception of competition seems to take another turn of what has been done in the past, particularly with the integration of space in the understanding of it's mechanisms. In this paper, we will try to see the effect of space, in the general sense, on the competition of establishments common to a specific type of activity coming from a single branch. And moreover in a limited space.
