The delimitation of economic systems may be carried out by means of the conception of hierarchical structure and order. The delimitation of economic systems should be performed on two planes: vertical and horizontal. A vertical plane is connected with the determination of hierarchical level, i.e., the level of the analysis of social existence. In turn, a horizontal plane is connected with the criteria of subordination of sub-systems distinguished at a given level of analysis. The traditional economy distinguished two levels of analysis: micro and macro. In the 20th c. three additional levels of analysis have been distinguished: micromicro, mezo and global. The article discusses the characteristics of analyses conducted at particular levels. The last part of t he article contains the examples of delimitation of economic sub-systems in four branches of economy: (i) theory of industry organization; (ii) regional economy and zoning; (iii) organization and management, and (iv) marketing.polinfo:eu-repo/semantics/openAccessArtykuł
