Development of an integrated entrepreneurship model based on the principles of circular and sharing economy: theoretical substitution and practical analysis

The object of research is the process of formation and development of modern entrepreneurship in the context of the transition from a linear model to a circular and sharing economy, which are currently focused on the principles of sustainable development. The paper analyzes the current state and prospects for the development of entrepreneurship, which operates on the principles of closed production cycles, extending the life cycle of products and reusing raw materials and materials. An integrated model of entrepreneurship based on the principles of a circular and sharing economy is proposed. The theoretical and practical essence of these economic models is considered, the principles of their construction are further developed, and significant differences from the traditional provisions of a linear economy are formed. It is substantiated that the gradual transition from a linear economic model of management to circular and sharing models of the economy is dictated by the presence of environmental challenges, as well as the limitation of natural resources. Trends in the field of sharing business, which are based on the joint use of resources by the asset owner and other consumers, are studied. The global experience of implementing these approaches has been analyzed and summarized, and the prospects for their development have been considered. It has been determined that over the past 10 years, the use of the circular economy concept in the world has increased 15 times (from 0.8% to 12% of enterprises), and the concept of the sharing economy has increased 10 times (from 0.2% to 2%). The research results confirm the integration of theoretical and practical provisions of the circular and sharing economy into global business models. This contributes to increasing the efficiency of resource use, increases the level of competitiveness of enterprises, and creates stable social and environmental benefits. Practical recommendations for Ukrainian entrepreneurs are proposed, the use of which will help adapt modern business to global trends in resource conservation within the framework of European integration and post-war economic recovery.
