Abstract

Dans le contexte d'une fin programmée du système des quotas laitiers, la valorisation du lait est une variable clé de la rentabilité des exploitations laitières. Le lait de vache tire sa valeur des différents produits de sa transformation. Les signes d'origine et de qualité constituent un facteur majeur de différenciation pour les spécialités fromagères mais aussi pour le beurre et la crème. Ainsi, la valorisation du lait dépend de sa composition mais aussi d'attributs qualitatifs du produit laitier ayant trait à son origine et sa typicité. Basé sur le Réseau d'Information Comptable Agricole (RICA), ce travail a donc pour objectif d'estimer la valeur implicite pour le producteur des attributs quantitatifs et qualitatifs du lait au moyen d'une méthodologie de régression hédonique grâce à des données de panel dans une période de forte variation du prix de ce produit (2006-2008). Sur cette base, nous donnons des estimations des prix implicites de la matière grasse et de la matière protéique, ainsi que la valorisation des différents signes officiels et professionnels de qualité compte tenu des contextes régionaux de production et de transformation étudiés. Mots-clés : qualité du lait, régression hédonique, signes de qualité, Réseau d'Information Comptable Agricole, France Is there a price for milk quality? A hedonic function estimate of dairy milk specific attributes. Abstract-In the context of a scheduled end of the milk quota system, the valuation of milk is a key variable in the profitability of dairy farms. Cow's milk derives its value from different products of its transformation. The origin and quality signs are a major differentiator for cheese specialties but also for butter and cream. Thus, the valuation of milk depends on its composition but also on qualitative attributes of the dairy product relating to its origin and its typicality. Based on the Farm Accounting Data Network (FADN), this work therefore aims to estimate the implicit value for the producer of the quantitative and qualitative attributes of the milk using a hedonic regression methodology applied to panel data in a period of strong change in the price of this commodity (2006-2008). On this basis, we give estimates of the implicit value of the fat and protein contents, as well as those of the various official and professional quality labels, taking into account the regional contexts studied, both in milk production and processing.
