[fre] Cet article explore la relation entre appartenance à un bloc d'alliance et performance d'innovation dans un réseau inter-organisationnel à base technologique, dans une perspective longitudinale. L'appartenance à un bloc d'alliance ou à un sous-groupe cohésif de firmes peut être considérée comme l'une des formes les plus solides de l'encastrement social. On peut attendre que la performance d'innovation d'une firme soit dépendante de sa position dans différentes configurations de réseau dans lesquelles elle est impliquée, ainsi que de la nature, radicale ou incrémentale, du changement technique. Après avoir discuté de ces diverses inter-dépendances, nous mettrons en évidence quelques propositions de base sur les effets de l'appartenance à un bloc d'alliance sur la performance d'innovation selon les conditions prévalantes du changement technique. [eng] The role of social networks in innovation diffusion remains a strategic question. In former works, we have introduced a relational learning, based on hebbian rule, that leads to a critical state, in which few agents reach structural positions of opinion leaders. In this paper, we show that the self-organization of an influence network, through social learning, is not a monotonie process, from the point of view of structural characteristics as well as of its diffusion performances. The notion of intermediarity, which derives directly from the concept of network, appears necessary to decrypt this evolution. By introducing the role of "weak ties" in the diverse diffusion regimes it is then possible to bring a new understan-ding of the phenomenon.
