Sudakov N. The sociological conceptualization of the social inequality phenomena as the factor of the structural differentiation of the social systems.

The sociological conceptualization of the social inequality phenomena as the factor of the structural differentiation of the agrarian, industrial and postindustrial social systems is presented in the thesis. The main cognitive contradictions and the specific of the theoretical reflection of the social inequality phenomena in protosociological, classical and postclassical sociological conceptions and theories are investigated. The new integral causal-empirical typological model of social inequalities that enables to differentiate global, regional and local types of social inequalities is proposed. The new definition of the "social inequality" concept is proposed. According to author's point of view the sense of this concept reflects the process of structural differentiation of the modern social systems which also represents the differences among of the social actors coexistencial positions as the results of the social distribution of the deficit recourses and rewards.
