The article is devoted to the study of circular economy, its concept; the main circular business- models, their essence and advantages in the practical application based on the analysis of researches of their introduction and use in the world and domestic companies are analyzed; features of the development of circular economy in Ukraine in disclosure of researches of sources of financing of innovative activity and a share of innovative enterprises in general scale are revealed; the expediency of introduction of energy-efficient and energy-saving technologies at the enterprises within the limits of socially responsible production is substantiated. The results of the study showed that the development of the circular economy in Ukraine is at a much lower level compared to the world, due to negative factors such as ignorance of the population and entrepreneurs the necessity of circular economy transition, lack of full and perfect legislation, the unpreparedness of enterprises change in favor of environmental friendliness. However, it is still an enterprise that is ready to act and change by implementing environmental solutions, such as energy-efficient technologies, thus contributing to its competitive position.
In the context of the need to move to a circular economy, scientists, politicians, businesses, consumers, public and international organizations are increasingly studying the basic principles and models, as well as their possible implementation and features of use. In addition, both domestic and international companies are trying to be socially responsible and implement energy-efficient technologies that reduce the consumption of energy resources, economic resources, increase the competitiveness of production.
This means that both foreign and domestic companies, at the same time, must clearly understand the methods, ways, and opportunities to achieve the most competitive position as a socially responsible enterprise.
Therefore, based on examples of implementation of methods and solutions in the field of circular economy in global companies, as well as using their experience, knowledge and skills, Ukrainian companies will be able to achieve at least the same level of social responsibility. However, it should be understood that these actions should be legally protected, which should serve as a regulatory framework developed by the state. Only with such bilateral work can Ukrainian enterprises and Ukraine in general become an example to follow for other countries.
