Abstract

Cet article présente une application expérimentale de la méthode d'estimation des flux d'échanges entre des régions par la minimisation de l'entropie croisée (mesure de Kullback-Leibler). Les flux interrégionaux ont été estimés pour 31 catégories de biens et services, entre trois régions du Québec en 1992: les régions métropolitaines de Montréal et de Québec et le Reste-du-Québec. La méthode, d'inspiration bayesienne, a permis de dégager des flux interrégionaux respectant les totaux marginaux provenant de matrices de comptabilité sociale régionales préexistantes, à partir de données sur les flux de transport jouant le rôle de distribution a priori./In this paper, we report on an experimental application of Kullback-Leibler cross-entropy minimization to estimate trade flows between regions. Interregional trade flows were estimated for 31 categories of goods and services, between three regions of the Province of Québec in 1992: the Montréal and Québec metropolitan areas, and the Rest-of-Québec. With this bayesian-style method, we were able to obtain interregional flows that respect the marginal totals taken from pre-existing regional social accounting matrices, using transportation flow data as a priori distributions.
