[eng] Empirical Study of Social Influence in Diffusion Phenomena - Cable and Fax in France by Alexandre Steyer and Jean-Benoît Zimmermann . Over the last ten years, diffusion models have been improved by including network externalities. We briefly outline the main approaches developed to date and describe the basis of an approach to take account of different interindividual influences in a population. We then present an empirical validation based on two contemporary examples in France. The first is cable television, which is expected to present social utility via mimetic effects. The second example is the fax, which presents strong interindividual externalities. Its utility stems from the possibility for players to use it to communicate with their contacts. [fre] Étude empirique de l'influence sociale dans les phénomènes de diffusion : . l'exemple du câble et du fax en France . par Alexandre Steyer et Jean-Benoît Zimmermann . Les modèles de diffusion se sont enrichis depuis une dizaine d'années par la prise en compte des effets d'externalités de réseau. Après un rapide survol des principales approches développées jusqu'ici, nous exposons les fondements d'une démarche visant à intégrer la différenciation de l'influence interindividuelle au sein d'une population. Nous présentons ensuite un travail de validation empirique sur deux exemples contemporains, en France. Le premier concerne la télévision par câble. Ce produit présente a priori une utilité sociale par effet de mimétisme. Le deuxième exemple concerne le fax. Ce produit comporte de fortes externalités interindividuelles. Son utilité dérive pour l'essentiel de la possibilité pour un agent de communiquer par ce moyen avec les personnes avec lesquelles il est en relation.
