Abstract

Un nouveau modèle de diffusion des innovations est construit au confluent des travaux de Bass (1969) sur la diffusion aléatoire et de ceux de Hägerstrand (1952) sur la diffusion spatiale. Le modèle repose sur une structure particulière du réseau social au travers duquel se propage le mimétisme. Cette structure est à la fois aléatoire et régulière. Le modèle obtenu est validé empiriquement en ajustement et en prévision à partir de données empruntées à Hägerstrand (1967), Bass (1969) et Rogers (1995).
