Abstract

[fre] Cet article examine la relation qui existe entre évolution technologique et comportement d'innovation des firmes d'un côté, performances économiques des firmes et évolution de la structure industrielle initiale, de l'autre côté. À partir d'une adaptation du modèle de Nelson et Winter, nous voulons faire apparaître un processus de différenciation des firmes dans leurs choix technologiques pour en montrer les effets sur l'évolution des structures industrielles. C'est une manière d'apprécier la dynamique contenue dans la relation structure performances en donnant un rôle central à l'innovation. A l'aide de simulations, nous observons l'évolution d'échantillons théoriques de firmes, posées identiques en début de périodes. [eng] We are using an adaptation of the Nelson and Winter's model to showing the process of firm's differentiation in the technological choice and this effect of the industrial structure. Those inquiring into the structure performance relation give a central place to the innovation and this uncertain nature. In using simulations, we observe the evolution of theoretical sample of firms wich hold similar characteristics at the beginning of time. This study permit to examining the relation that exists between technological evolution, innovation, firms performances and technological choices.
