    This paper presents estimates of the patents-R&D relationship across French regions over the period 1991-1996, using an error component model with spatial dependence. The theoretical framework examines the spatial spillovers effects which can be caused by the technological or geographical proximity of regions. The model is estimated by Maximum Likelihood. The empirical results indicate a significant impact of R&D expenditures upon the patenting activity at the regional level. The technological spillover is positive but its statistical significance depends on whether the regional effects are fixed or random. On the other hand, there is no evidence of geographical spillover. Cet article présente les estimations de la relation brevets-recherche et développement (R&D) au niveau des régions françaises sur la période 1991-1996, en utilisant un modèle à erreurs composées avec dépendance spatiale. L’approche analytique prend en compte les effets des externalités spatiales des activités de recherche causées par la proximité technologique ou géographique des régions. Le modèle est estimé par le maximum de vraisemblance. Les résultats empiriques montrent une influence significative des dépenses de R&D sur l’activité des dépôts de brevets affectés aux régions. Les externalités technologiques sont positives mais leur signification dépend du caractère fixe ou aléatoire des effets régionaux. Par contre, les externalités géographiques demeurent absentes.
