R´esum´e - Nous nous int´eressons `a l’influence de la localisation spatiale des individus sur la mani`ere dont ils interagissent : le cas d’´etude auquel nous nous int´eressons est celui d’un cor- pus d’actes notari´es du Moyen- ˆAge. Dans ce corpus, les individus interagissent par le biais de transactions communes qui sont g´eo-localis´ees. Ce travail cherche `a quantifier l’impact de la localisation g´eographique sur le r´eseau de relations des individus. Comme positionne- ment g´eographique et relations des individus sont construits `a partir de la mˆeme source (la liste des transactions auxquelles chaque individu a particip´e), un test de Mantel classique est inad´equat : nous proposons une m´ethodologie bas´ee sur une adaptation du test de comparaison de distances que nous illustrons dans ce contexte.
