The author uses the example of alternating mono-national and multinational types of ethnic diversity management to consider the mechanism of consistent reproduction of westernization and auto-modernization. The first type appears as a result of copying European institutional models, and the second type emerges as a result of adaptation of western borrowings to Russian realities. Each phase of Russian modernization cycles turns out to be connected with the work of one of dominants: the first phase - with westernization, the second phase is transitory and the third phase is due to auto-modernization. A conclusion is made about the dependence of institutional models of ethnic diversity management on the inversion mechanisms of socio-cultural dynamics.
