[Autom. eng. transl.] We propose an economic interpretation of the notion of dominance for the evaluation of concentrations in oligopolistic markets. An oligopoly identifies a context in which companies make interdependent decisions. To assess the establishment of a dominant position in oligopoly it is therefore necessary to reinterpret the definition of the dominant Court of Justice as "interdependence of behaviors". To this end, it is suggested to look at the circumstance that a concentration induces, to a significant extent, a stable and asymmetrical modification of the strategic incentives of the concentrated company. Studying the implications in oligopoly models with homogeneous products and with differentiated products, it is shown how this reading allows to highlight a substantial equivalence between the European criterion of dominance and the American criterion of "substantial reduction of competition"
