Abstract

Two great alternative hypothesis are possible in the analysis input-output : the model may be demand-driven (Leontief) or supply-driven (Ghosh). To test the consistency of these hypotheses on the long term, this paper studies the interest of proportional filters (comparison of column or row coefficients) and the interest of the biproportional filter for the temporalcomparison of input-output matrices. An application is proposed for France between 1980 and 1993. The result is the following : in the long period, there are more sectors supply-driven than demand-driven (i.e. row coefficients are less variable than column coefficients for the majority of the sectors). (FRE) Deux grandes hypothèses alternatives sont possibles dans l'analyse input-output : le modèle peut être piloté par la demande (Leontief) ou piloté par l'offre (Ghosh). Pour tester la consistance des deux hypothèses sur le long terme, ce papier étudie l'intérêt des filtres proportionnels (comparaison des coefficients colonne et ligne) et du filtre biproportionnel pour la comparaison temporelle des matrices input-output. Une application est proposée pour laFrance entre 1980 et 1993. Le résultat est le suivant: dans la longue période, il y a plus de secteurs pilotés par l'offre que pilotés par la demande (c.a.d. que les coefficients-ligne sont moins variables que les coefficients-colonne pour la majorité des secteurs).
