Abstract: The article is dealing with the identification and analysis of various variants of binary division (dichotomy) of the international space activity that is considered as a set of implemented projects or market sales. The key aspects of the modern development of space activities influence not only the technological, but mainly the institutional, organizational and economic features of interaction between participants in space activities and the effectiveness measurement. Such binary divisions of space activities as "applied vs.non-applied", "commercial vs.non-profit", "public vs.private", "budget vs.non-budget " are considered. In addition, an important aspect of the separation of the results of space activities into products/services and projects is considered. Further directions of research in this area are shown, including the development of model indicators and criteria for the effectiveness of space activities in their various forms and types.

Abstract: The international space market and associated value chain are considered. We consider the generally accepted approaches promoted by the Satellite Industry Association to analyzing the structure and quantitative parameters of the space products and services market based on the gross turnover approach as well as government funding specifics. The approach suggested by G.Graziola of Bergamo University is analyzed that is based on the space industry/space economy dichotomy. The market structure is interpreted based in the Russia national standardization and experience. The prerequisites for the formation of a substantially different market structure are considered, based on the idea of the added values calculation along the value chain.
