The article describes the growth trend of market concentration in Russian industries, which is the result of the firm's competition for a leading position in the market. Antitrust policy in Russia and foreign countries is aimed at countering the formation of cartels. Their identification is associated with great difficulties. The article proposes a methodological approach to assessing the level of concentration and the results of industry activity, if firms have formed strategic groups (cartels). The essence of the approach is to use the apparatus of the theory of industrial organization in the study of oligopoly markets. The initial version of Cournot, in which coalitions act as market participants, is taken as the basis. This approach allows us to evaluate the effectiveness of the industry on the basis of parameters such as profit, output of coalitions and enterprises, average total costs, industry profitability (Lerner index), as well as calculate the real level of market concentration taking into account the tendency of cartelization firms. The actual level of concentration corresponds to a certain number of coalitions and their composition, which functioning gives the best approximation to the statistics of production volumes and shares of enterprises in the market.
