Honcharuk I. Formation and development of multi-sided markets under globalization.

The dissertation is devoted to the comprehensive study of trends and contradictions of the formation and development of multi-sided markets under globalization with the purpose of providing methodological and practical recommendations for improving the institutional provision of their regulation. The author analyzes the theory of multi-sided markets and outlines five stages of its evolution: research (1) networks and network connections, (2) network effects, (3) classical bilateral markets, (4) multi-sided markets, (5) multi-sided markets in conditions of the global digital economy. Based on the study of the essence, characteristics and types of multi-sided markets, the author proposes definitions of the essence of the multi-sided market as a set of economic relations that arise between sellers, buyers and intermediaries (firm-platforms) and are characterized by positive network effects; the firm-platform as a structuring entity of the multi-sided market that has a unique resource – a digital network (technology platform), provides for the interaction of economic actors on the Internet and positive network effects. Taking into account the number of intermediaries in the market allowed to supplement the classification of multi-sided market structures by the level of competition and to distinguish the following types of markets: monosazonia, oligosazonia, polysazonia. The development and complication of competitive relations between firm-platforms necessitates the improvement of their state regulation. It is about updating antimonopoly policy tools; working out a method for their economic analysis in view of the network effects by determining commodity-based and geographic boundaries of the market, assessing the monopoly power of firm platforms; analyzing mergers of firm-platforms; defining the competitive level of prices for goods and services.
