The telecommunication networks of companies have different attributes which assumed fix and the consumers have idiosyncratic tastes for these attributes. The networks are mandated to interconnect and the access charges are determined by companies cooperatively. The two telecommunication network companies are engaged in a price competition to attract consumers. Each consumer selects a network and determines the consumption of the telecommunication services. The regulation policy of the telecommunication market is studied for this model.</abstract><trans-abstract xml:lang="ru">В этой статье строится экономико-математическая модель рынка телекоммуникаций в случае дуополии. На базе этой модели проводится анализ равновесных тарифов на телекоммуникационные услуги для этого типа рынка. Также исследуются возможные методы государственного регулирования рассматриваемой дуополии.</trans-abstract><kwd-group xml:lang="en"><kwd>mathematical modeling</kwd><kwd>telecommunications</kwd><kwd>pricing</kwd><kwd>marketequilibrium</kwd><kwd>state regulation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>математическое моделирование</kwd><kwd>телекоммуникации</kwd><kwd>ценообразование</kwd><kwd>рыночное равновесие</kwd><kwd>государственное регулирование</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Armstrong M.
