Résumé / Abstract
The aim of statistical clustering procedures is to create space zoning systems particularly from flow data. The key concept of 'functional region', derived from the gravity model, can be applied to define a multilevel space from aggregate flows. Interactions are then observed as a measure of functional distance where a high level of interactions indicates short level of functional distance. The purpose of this paper is to examine firstly, the persistence of global world forces over time in terms of spatial structures and secondly, the possible changes of the main world powers, such as 'Europe', according to three types of flows: trade, financial and migrants' flows. In order to do that, we carried out an analysis based on the socalled continuous Intramax procedure (Masser & al., 1975, 1977) on the selected matrices on two periods. Firstly we summarise the theoretical basis of clustering flows and the particularity of the Intramax one. Secondly, we present the methodology and results obtained on the different flows. Finally, a cross analysis leads us to emphasize the specificity of Intramax regarding other procedures.
