THEORETICAL AND METHODOLOGICAL BASES OF IMPROVING THE ASSESSMENT OF THE EFFECTIVENESS AND SYNCHRONOUS FUNCTIONING OF A COUNTRY'S SOCIOECONOMIC SYSTEM UNDER CONDITIONS OF TRANSFORMATION

The processes of transformation of the socioeconomic system are realized through various mechanisms, where the mechanism of structural change is a key one. A structural change occurs in economic systems at various levels: at the level of a person and household (nanolevel), a company (microlevel), an industry or region (meso-level), the level of the national economy (macrolevel) and global economy (megalevel). Eventually, a structural change stimulates the processes of an appropriate level. According to the authors' opinion, the issues of efficiency and synchronous functioning emerging in the process of transformation of the socioeconomic system of a country are the most relevant. This article considers the problem of evaluating the results of transformational changes, which is the most important for the development of the theory of economic systems. Also, this problem may determine the direction of reproduction processes in the national economy at the theoretical and applied levels
