Akhiezer, L. Kogan and O. Yanitsky. Drawing on relevant scientific literature and my professional experience as a sociologists and city planner, I came to the following conclusions. First, any urbanization process is a part and parcel of a particular mode of production and social reproduction. Second, at the same time a particular urbanization process has its own specific. Third, nowadays, the current urbanization process in Russia is a result of complex transformations generated by such fundamental processes as a transition to market economy, globalization and to the transition to the Fourth scientific and technological revolution (STR-4). Fourth, the Chicago School principles of human ecology and its transformations in Russian conditions as well as their changes in the digital era are analyzed. Fifth, a current urbanization process in Russia is inseparable from its social, natural and built environment. Sixth, the Fourth scientific and technological revolution coupled with globalization processes sharply changed the time-space relations and a dynamics of urban processes. Seventh, the various metabolic processes are the basement of current urbanization. Eighth, a distance between the mega-cities and their built periphery expands. Ninth, under modern conditions an urban dweller lives not in cities and towns but in global information-communication network that urge her/him to be mobile and therefore less dependent on family and local community life.
