The article substantiates the problem of forming baby economy as a factor of national economic development in the global environment. The main baby economy evolution directions as a component of the nanoeconomic system are formulated in the course of research. In addition, Ukraine’s baby economy subsystem, particularly the practice of growing up, socialization and relationship process, is analysed. It has been revealed how little people in this country can influence the course of economic development. The factor analysis is conducted on baby economy factors’ impact on GDP per capita which determines that our GDP manufacturing does not actively depend on the performance of baby economy. This dependence is 0.57. Therefore, it is necessary to introduce the levers of deploying baby economy processes in Ukraine’s economic environment. Furthermore, it has been estimated that the number of people with higher education is gradually increasing as well as the number of foreign students that results in attractiveness of Ukraine’s higher education. As a result of research, the conclusions are based on the necessity of updating baby economy and the beginning of the national economic system development, taking into account the formation of common approaches to education and upbringing. World experience shows that if the economic behaviour of a child is developed by the appropriate education, the level of national economy adaptation to the global environment becomes a decisive issue.
