In the conditions of digital transformation, the issues of developing the organizational-technological structure of the formation and management of model-type new-generation enterprises are of special importance. In this aspect, Artificial Intelligence, cloud, etc. the dynamic development of innovative digital technologies, the relevance of their application in the production, service, and decision-making processes of enterprises, in the improvement of management efficiency, in the development of the organizational and economic structure, is substantiated. Some problems have been revealed based on the overview analysis of the scientific research works related to the state of processing of the problem. Those problems were used in the synthesis of the new-generation enterprise model. The considered issues include: 1)Development of a structural model reflecting some advantages using enterprise architecture management approaches, 2)Development of a conceptual model of effective management of innovative enterprises based on digital twin technologies, 3)Innovation in the enterprise, market conditions, economic efficiency and analysis of indicators characterizing the positive relationship between external and internal factors that support development, 4)Development of the model of the process of designing the organizational structure of enterprises and the development of the main stages of the process of improving the organizational structure, 5)Analysis of the impact of information technologies on the organizational structure of the enterprise, 6)Parametric analysis tools ways of optimizing the organizational structure of the enterprise management, proposing innovative methods to ensure the high quality of the organizational structure of its management, 7)Using the enterprise architecture approach in conceptual modeling for enterprise management, 8)Enterprise architecture within the framework of the open innovation concept and development of investment models for IT architectural projects, offering investment and evaluation models, etc. The role and importance of model-type, new-paradigm innovative digital enterprises in the formation of the new generation digital economy has been studied. Relevant analyses were conducted on the scientific-theoretical bases of enterprise management, existing approaches, and specific features, and scientific theories that determine its effective organizational-technological structure. Functional structural models of enterprise architecture at different levels and some of their elements have been defined. The characteristics of some platforms of the main enterprise architecture are studied, the structural elements, levels, and advantages of The Open Group Architecture Framework are shown. The elements of the organizational-technological structure of the management of model-type new-generation enterprises have been determined, and the functional stages of its organizational structure improvement have been worked out. Contradictions and defective elements of the enterprise's organizational structures have been identified. Recommendations were made regarding the conceptual model of the organizational-technological structure of the management of model-type new-generation enterprises. Conceptual linking blocks of the organizational-technological structure of the management of model-type new-generation enterprises have been proposed. Relevant recommendations were given for the development of the organizational-technological structure of the management of such enterprises for the transition to the digital innovation-based development stage on the Industry 4.0 platform.
