Some theoretical and practical aspects of integration relations in regional groupings has not been studied and require further analysis. Economists and other practitioners stress that there has not been developed yet a unified theory of integration covering various aspects of this process. Analysis of domestic and foreign scientific literature shows that currently there is no clear definition of the «differentiated economic integration» concept, which is a system of alternative theories of international economic integration.In this study the emphasis is placed: firstly special attention is paid to economic integration, not political. Initially, differentiated integration was positioned as multi-level governance in the field of decision-making that allows us to speak about the political nature of the concept. In this article, we attempt the study of differentiated integration through the prism of economic categories. Secondly, in accordance with the subject of study, special interest triggers not the classical theory and approaches of economic integration, but the system of alternative theories of economic integration.
