ENThe concept of sustainability and, particularly, of sustainable development dominates in the literature among the most ambitious and controversial concepts. The knowledge and researches of state, evolution or development become not only the original means of generation of socio-economic science knowledge, but also an alternative in analyzing strongly sophisticated development problems pertaining to such complexes as city, region, field of activity or state. Finding the ways of such knowledge conversion into the field of science is complex, but necessary. Abundant researches of sustainable development become oriented towards the analysis of multifactor nature of development, or its universality. The paper uses the category of universally sustainable development, which is treated as a qualitatively-innovative instrument of thinking. Universally sustainable development is being analysed through the reality cognition prism of experts pertaining to the four blocks of knowledge, improving the idea of round table already developed in previous researches made by the authors. The impact of universally sustainable development on country economic efficiency and national self-sufficiency is analysed. [From the publication]
