The past quarter of a century since the collapse of the Soviet Union has shown that it is quite difficult to confront the realities of the global economic and political situation separately for post-Soviet countries, the way out of this situation is the process of integration into unions and associations. This process deserves a separate close attention on the part of economic science as a new one, which did not exist before, in this connection the chosen topic is up to date. The purpose of this article is to identify the patterns of transformational reconstructions of the economies of the post-Soviet countries from the position of system analysis. Such general scientific methods as analysis and synthesis, as well as proprietary methods of system analysis (methods of decomposition of complex systems, methods for disclosing «black boxes») and statistics (tabular, graphical, coefficient, groupings, correlations) are used as research methods. The main results of the study can be called: before 1970, the growth rates of the Soviet economy were comparable to those in the United States, then the US economy shows itself as a stable system, and internal contradictions and the impact of the external environment led to the death of the Soviet Union. The resulting post-Soviet republics tend to integrate around such centers of attraction as the European Union, Russia and China. The results obtained will be useful to researchers in the field of transition economy, as well as employees of state institutions for the formation of a policy of integration of Russia and the countries of the post-Soviet space.

Keywords: statistics, system analysis, bifurcation, dynamics, transformation, Soviet Union, Post-Soviet countries.
