French. L' objectif de cette etude est d' analyser la relation entre l' efficacite technique et la taille de l' exploitation. L' efficacite technique est estimee pour un echantillon d' exploitations cerealieres du Sers (region du Kef, Tunisie) .En premiere instance, une fonction de production du type Cobb-Douglas a ete estimee. Successivement, une fonction de production frontiere a ete ajustee moyennant la methode des moindres carres ordinaires corriges (M.C.O.C). En dernier lieu, l' efficacite technique des exploitations cerealieres par strate (petites, moyennes et grandes exploitations) a ete calculee en utilisant la methode de mesure adoptee par Timmer. Les resultats montrent une relation inverse entre l' efficacite technique et la taille de l' exploitation.

Technical efficiency for a sample of grain farms in Sers (Kef area, Tunisia) has been evaluated. First of all, a Cobb-Douglas production function has been estimated. Secondly, a deterministic frontier production function has been estimated using the corrected ordinary least square (C.O.L.S) technique. Lastly, technical efficiency using Timmer measures has been calculated for three types of grain farms (small, medium and large farms). The results show an inverse relationship between farm size and technical efficiency.
