Abstract

[fre] Cette étude est une partie de celle, plus vaste, entreprise à la demande de la CEE sur les coûts de production des principaux produits agricoles. Elle repose sur l'idée que la prise en considération des marges des cultures à l'hectare permet de mieux comprendre les substitutions, orientations et spécialisations en cours dans le secteur de grande culture européen, brièvement retracées à l'aide d'un bilan de l'évolution des superficies des principales cultures en France, Allemagne, Italie et Royaume-Uni. C'est pourquoi des marges pour diverses activités blé tendre, blé dur, orge, maïs, oléagineux, betterave sucrière et pomme de terre ont été estimées par voie économétrique pour chacun de ces pays à l'aide d'un modèle basé sur une régression linéaire multiple et sont comparées systématiquement entre elles : on s'interroge sur la mesure selon laquelle, au-delà des prix à la production et des rendements physiques, elles contribuent à une explication du comportement des agriculteurs en matière de choix de leurs systèmes de production. [eng] This study is part of a larger one, requested by EC, devoted to the production costs of the main agricultural crops. It is based on the idea that taking into account the gross margin per ha of crop can throw some lights on the substitutions, orientations and specializations under way in the European cash crops sector, which are summarized by an analysis of the evolution of arable land to the main crops in France, Germany, Italy and United Kingdom. For different crops, soft wheat, hard wheat, barley, corn, oleaginous crops, sugar beet and potato, gross margins have been estimated, for each of these countries, from an econometric model, based upon a multiple linear regression. Their influence on the behaviour of farmers when they plan their farming systems, is being discussed, beyond the impacts of prices and yields.
