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.

The article is devoted to the development and implementation of the conceptual model of effective management of innovative enterprises based on digital twin technologies. As a result of digital transformation, the relevance of creating a digital twin of the innovative enterprise and the products/services produced there is justified. The necessity of developing the high technologies sector and the complex application of their results in relevant areas was noted. The features of the application of Industrial 4.0 platform components in the effective management processes of innovative enterprises have been studied. Organizational and technological issues of effective management of the activities of innovative enterprises were analyzed. In order to digitalize the economy on an innovative basis, directions for improving the ICT infrastructure have been proposed. The characteristics of science and technology-intensive product production in realizing and increasing the innovation potential of enterprises have been investigated. The state of the global market for the production and use of high-tech products has been analyzed. The ranking of some world countries according to the Global Innovation Index is given. Many issues related to the innovative digital development of industrial-economic systems have been revealed. A perspective conceptual development model of industrial-economic systems based on innovative digitization processes has been proposed. The stages of formation of technical and technological paradigms of development of industrial-economic systems are given. The economic-technological features of digital twin technologies in the conditions of digital transformation have been explained. The application areas and features of the digital twin technology in increasing the efficiency of the innovative activity of the enterprise were studied. The results that can be created by the application of digital twin technology in innovative industrial-economic systems have been brought to attention. A SWOT analysis of the process of using digital twins in the management of innovative industrial-economic systems was carried out. The impact of digital twin technology development on sustainable innovation processes has been investigated. The creation of digital twins for the organization and management of the activity of the innovative industrial-production enterprise and the expanded architectural system of its concept were proposed. Information about the structural subsystems of the conceptual model of innovative enterprises based on digital transformation was provided. As a result of extensive scientific analyzes and researches, a number of proposals and recommendations were developed on the effective application of digital twin technologies in the economic sphere and processes.

The article presents the science, technologies and innovations as foundations of modern economic development. The purpose of establishing complex-structured innovation structure and their functions are analyzed. An effective organizational-economic structural model is proposed for the management of their performance. Production functions, allowing central management institution to use the resources effectively and enterprises within the institution to operate with the whole production strength, are developed. Parameters that cannot be assessed directly as innovation, innovation capacity, science capacity and environmental availability are included in the modeling process. Hierarchic models are developed corresponding to the problems posed to each structure. Among models with various levels, a conceptual algorithm is developed for the purpose of finding a coordinated solution on product/service output based on the efficient utilization of scarce resources. Some suggestions have been given on the basis of modeling the activity of innovative enterprises of different levels with complex structure on its perspective development directions.
