The article is focused on theoretical considerations aimed at defining and delimitation of the ranges of public and private spheres. Such considerations are justified by the fact that the theory of state and of public sector, as well as fundamentals of economic analysis and regulation of the public sphere, constitute a relatively poorly developed part of the theory of economics. On the other hand, the public sphere and the demand for effective methods of its development become larger due to increasingly complicated social, political and economic relations, an increasingly tough competition and bitter rivalry, the density of population in most parts of our globe and a deeper and deeper disproportion in the development of particular areas.
