The purpose of the research is to present the features of digitization of business processes in enterprises as a foundation on which the gradual formation of Industry 4.0 and the search for economic growth in new virtual reality, which has every chance to be a decisive step in implementing digital strategy for Ukraine and development of the innovation ecosystem. Key problems that arise during the digitalization of business processes in enterprises are presented, among which are: the historical orientation of production to mass, “running” sizes and large batches; large-scale production load; the complexity of cooperation and logic between production sites. It is determined that high-quality and effective tools of innovation-digital transformation in the conditions of virtual reality should include: a single system of on-line order management for all enterprises (application registration – technical expertise – planning – performance control – shipment); Smart Factory, Predictive Maintenance, IIoT, CRM, SCM. Features of digital transformation in the part of formation of enterprises of the ecosystem of Industry 4.0 are revealed. The capabilities and benefits of using Azure cloud platform in enterprises, which includes more than 200 products and cloud services, are analyzed. Azure is said to support open source technologies, so businesses have the ability to use tools and technologies they prefer and are more useful. After conducting a thorough analysis of the acceleration of deep digitalization of business processes by enterprises, authors proposed to put into practice Aruba solution for tracking contacts in the fight against COVID-19. Aruba technology helps locate, allowing you to implement flexible solutions based on Aruba Partner Ecosystem using a USB interface. It is proposed to use SYNTEGRA – a data integration service that provides interactive analytics and provides data models and dashboards in order to accelerate the modernization of data storage and management, optimize reporting in the company and obtain real-time analytics. The possibilities of using Azure cloud platform during the digitization of business processes of enterprises of the ecosystem of Industry 4.0 in the conditions of virtual reality are determined.

The purpose of the article is generalization of features of expediency of the creation of innovative parks in Ukraine. Practical output of the results consists in the discovered success factors of the activity of innovative parks in Ukraine in order to create new opportunities of innovation development of the country.Current organizational and functional system of innovative entrepreneurship of Ukraine is an imperfect, complex and by all indications, is in the process of formation. It is assumed that infrastructure of international educational innovative hub can structurally corrected according to the area which operates a hub that is: stimulate the dialogue between academics, businessmen and government officials; provide an interactive exchange of explicit and implicit knowledge; generate shared vision on adaptation measures of dynamic environment.Evaluation of the results of scientific and pedagogical activities of working group of innovative hub should be made for following indicators: development of skills of teaching and research work; introducing of innovative approaches for practical individual activity; formation of innovative approaches for collective practical activity; working on the chosen scientific and methodological theme.Main advantage of proposed university innovative hubs is that laid all necessary foundations in order to high school could be as soon as effectively integrate the results of university, academic and sectoral sciences of Ukraine, well as advanced research results of scientific world community in the development and implementation of innovative projects and development innovation.

PURPOSE: The disclosure of the content of the synergetic effect, as a result of network interactions of development institutions in a new economic virtual reality, and the presentation of the general characteristics of their relationships through knowledge of the functioning of clusters, which in the XXI century occurs during the digitalization of the economy, resulting in digital products/services and various platforms. METHODOLOGY: On the basis of dialectical, systemic and matrix methods and using the institutional-network approach, the characteristic features of network interactions of cluster formations in the conditions of virtual reality are studied, which are becoming the norm today, a good quality and effective rule for the practical implementation of various sectors of the economy in the course of digitalization of the economy. The method of comparison is used in terms of conditions for the formation of an innovation-digital cluster from the standpoint of the theory of institutionalism. FINDINGS: Network cooperation in the conditions of virtual reality demonstrates synergetic effects through new forms of qualitative accumulation and an increase of new knowledge, which occur through their network replication (division), and innovative growth is the result of the formation in the economy and society of a new, network model of coordination of connections, network cooperation of new quality, constantly adjusted by digital tools. The synergistic effect of networking creates a new phenomenon of growing marginal utility and growing marginal productivity from innovative glocalization and digital globalization. The greater the scale of innovation and digital activities is in the conditions of virtual reality, the greater the efficiency is of the use of additional resources. The effect of scale is especially pronounced within the network, which uses the standards produced and tested by it. IMPLICATIONS FOR THEORY AND PRACTICE: It is proved that the synergetic approach used in the formation and development of innovation-digital clusters is considered through the prism of the relationship “subject – subjective relationship of innovation-active organizations and digital enterprises.” In addition, in our case, this effect lies in the plane of restructuring the “old” development institutions in the “new”, under the influence of the relevant institutional and legal basis, systemic and comprehensive modernization and diversification of all sectors of production, improvement of the innovation and investment situation, construction of effective innovation and digital virtual-real infrastructure of the European standard, implementation of clustering of the economy using the opportunities of network cooperation.. ORIGINALITY AND VALUE: The content of a virtual slice of network interaction of cluster formations in the conditions of virtual reality offered by the authors is revealed; the authors’ vision of its structural elements is given, as from a digital network augmented and virtual socio-economic reality; the taxonomy and categorization of terminology with the help of which it is possible to reveal the formation of network cooperation in the conditions of virtual reality and its further development are investigated; on the basis of the conducted deep theoretical and methodological analysis and the presentation of a retrospective of innovation and digital changes, a step-by-step transformation of cluster formations is shown. The basis of network economy is network institutions, entities, organizations, in addition, it forms an environment in which any business entity or individual, which, no matter where it is in the economic system, has been able to communicate easily and at minimal cost with any other company or individual about working together, trading issues, or know-how, or just for fun in the conditions of the new virtual reality.

Entrepreneurship is one of the pillars of the economy of the country and covers all sectors irrespective of ownership forms. Currently, this activity is increasingly spreading in rural areas. Our research results on transformation in the agricultural sector of the economy show that it is due to the development of entrepreneurship and strengthening entrepreneurial orientation and improvement of business environment economic entities in rural areas they were able to quickly and efficiently adapt to market conditions and to enter the foreign market, therefore, the purpose of the paper is to define the basic principles and the principles of entrepreneurial activity, its specifics and trends in agriculture and rural areas, to show the beginning and the development of collective and individual entrepreneurship. Methodology. The theoretical and methodological basis of the research is the dialectical method of cognition and systematic approach, through which theoretical and methodological foundations of the development of business interactions in the agricultural sector in terms of institutional transformations. The results showed that in the article, the methodical design determining the nature and characteristics of agricultural business organically integrated the concept of institutional knowledge of the economic order, which allows us to identify the evolutionary concept of the formation of enterprises; the structure of the institutional system of entrepreneurship in the context of the evolution of this concept. Practical implications. The studied institutions create incentives for the development of science and education, encourage the mobility of production factors, and facilitate the transfer of scientific and technical information and the introduction of new technologies, promoting entrepreneurship and innovation. Conversely, inefficient institutions reduce the potential level of well-being, reduce reliability assurance of property rights, and enforce contracts. Value/originality. Given systematic and analytical characteristics of the effects, significance, dynamics of development of agrarian entrepreneurship in the context of institutional transformation, show the paradox, the stability of the institutional environment will not soon be reached, therefore, the dilemma of institutions remains unresolved. In general, the institutional transformation has ensured the formation of a mixed economy, the real pluralism of forms of ownership and agricultural management even if they are not yet fully institutionalized in the market. Transformations in the business environment we call the transformation of institutional conditions for the development of economic formations. Institute of entrepreneurship for the imperfections of the rules and conditions of economic interactions has not yet become mutually beneficial by the Institute for functional participants. Analysis of the development of agrarian enterprises in the conditions of institutional transformations proves the inconsistency of the institutional framework of entrepreneurial activity, which leads to a decrease in the number of enterprises – economic entities, non-transparent activities of business entities, the removal of landlords from participation in the activities of enterprises.
