Les politiques de soutien financier à la R&D se sont multipliées depuis les années 80 dans les pays de l'OCDE avec une utilisation croissante des mesures fiscales. Cependant, il existe assez peu d'études mesurant l'impact macroéconomique de ces mesures sur l'investissement privé en R&D. L'objectif de cet article est d'analyser l'impact et la complémentarité des politiques internes de soutien financier à la R&D mais aussi l'influence des politiques externes sur l'intensité de la R&D financée par le secteur privé. En utilisant une base de données couvrant 25 pays de l'OCDE sur la période 1990-2007, nos estimations en panel dynamique montrent que seules les politiques internes de soutien financier indirect (incitations fiscales) influencent significativement l'intensité de la R&D privée. Si les instruments de soutien direct (subventions et prêts) n'ont pas d'impact significatif, il apparaît que leur renforcement nuirait à l'efficacité des mesures indirectes. Alors que la R&D publique externe semble dynamiser l'investissement privé en R&D, les politiques extérieures de soutien financier (direct et indirect) ne montrent pas d'influence significative.
