Les systèmes urbains français : une approche relationnelle

Abstract

This article explores the interactions between the French cities from a multi-dimensional and multi-scale approach. Most of the time, these relations are analyzed in a segmented way, focusing solely on one dimension among a multifaceted reality. To take into account the great diversity of exchanges, we simultaneously consider several types of inter-city links, reflecting individual mobility, economic relations and scientific partnerships, on which we apply flows selection methods and a scoring approach. These methods also allow distinguishing several interdependent scales of territorial dynamics: first, twenty six local urban systems are identified. Comparisons between these systems are conducted according to their more or less polarized organization and to the nature of the flows within these systems. On the other hand, the horizontal relations between regional urban centers are analyzed taking into account the range and diversity of interactions and also according to the way local and regional urban systems connect to each other. Finally, relations with Paris are highlighted depending on the specialization of these links and the size of the cities involved.
