Abstract

Bien que la créativité humaine soit au coeur du processus d’innovation, peu d’attention a été accordée à la dimension individuelle dans l’analyse de l’activité d’innovation. L’objet de ce travail est d’étudier les déterminants de la productivité des inventeurs individuels. Contrairement à d’autres études, notre hypothèse est que le stock de connaissances de l’inventeur n’est pas homogène. Aussi, nous élaborons un modèle qui ‘augmente’ les spécifications traditionnelles par l’introduction des facteurs de diversité d’une part et de cohérence d’autre part de la base de connaissances des inventeurs. Les résultats des estimations économétriques réalisées sur les données de brevets des inventeurs français et britanniques valident l’hypothèse d’une influence positive de ces deux facteurs sur la productivité des inventeurs individuels. Ils mettent également en évidence la présence d’un effet indirect de la cohérence sur la productivité de l’inventeur : plus la cohérence de la base de connaissances de l’inventeur est grande et plus l’impact de la diversification technologique sur sa productivité est élevé.
