Abstract

L'évolution de l'agriculture française est caractérisée par la concentration et la spécialisation des exploitations. Dans le cadre d'un équilibre concurrentiel comportant un nombre fini d'exploitations, la compétitivité relative des exploitations diversifiées et des exploitations spécialisées est décrite au travers de l'évolution différenciée des économies d'échelle et des économies de gamme. L'approche théorique montre comment l'évolution des prix des facteurs de production permet d'expliquer, au travers de ces changements techniques, la spécialisation des exploitations agricoles. L'analyse empirique propose une interprétation de la dissociation des productions animale et végétale, observée dans le secteur agricole.
