Object is the processes of digital transformation of domestic business structures, focused on changing their business models and improving the efficiency of their implementation. Purpose is substantiation and development of theoretical and methodological provisions, scientific and methodological approaches and practical recommendations for the rational organization of the process of digital transformation of business structures as an imperative of their innovative development. Research methods include morphological analysis, generalization and scientific abstraction, dialectical cognition, deduction and induction, historical and content analysis, questionnaires, system analysis and formalization of complex structures, expert assessments, economic-statistical and comparative analysis, economic-mathematical modeling, cluster analysis data, grouping and systematization, systems theory and systems approach, decomposition, graphical and tabular representation, abstract-logical. For the first time, it has been proposed: a digital platform for determining and monitoring the Index of Digital Transformation of Business Structures has been developed, which consists in automating the collection, processing and visualization of data on the state of digital development of business structures, which allows assessing their level of digital maturity in order to increase this level in the process of digital development of the enterprise; developed a polystructural scientific and methodological approach to determining the Index of digital transformation of business structures, which has the characteristics of a complex system "HIT" which involves the separation of four groups of indicators, each of which contains its own system of subindicators with appropriate weights; formed a theoretical and methodological approach to building the architecture of the "road map" of digital transformation of business structures, which is based on the successive passage of 8 basic steps, the results of which generate specific recommendations for the implementation of digital business transformation; what has been improved is scientific and methodological approach to systematization of business processes of the enterprise, which allows to differentiate business processes, which allows to identify priorities in planning and organization of digital business transformation processes to maximize the usefulness of their impact on overall business results; scientific and methodological bases of structuring the innovative business model of the enterprise, which covers the structural configuration of all business processes, which allows to coordinate it with the organizational system of the enterprise and decide on the use of the most effective digital technologies in functional support of enterprise development; theoretical and methodological provisions of digital transformation of business structures, which provide for the systematic structuring of business processes, business models, factors, indicators of digital transformation of enterprises; scientific and methodological approach to generating and processing respondents' answers on the importance of groups of indicators to determine the level of digital maturity of the enterprise, which involves the application of unification and coding of sociological research results based on a questionnaire with subsequent automation of the calculation process; methodological bases of clustering of small and medium business structures in terms of their digital maturity, based on the study of the features of two approaches - iterative and hierarchical - with further justification of the method of agglomerative hierarchical clustering to solve mixed data processing problems; has been further developed: the conceptual and categorical apparatus of the study of the processes of digital transformation of business structures in terms of clarifying the definitions of "digital transformation of business", "business model"; classification features of innovations in which the group of innovations arising in the course of the organization of digital transformation of business is allocated; scientific and conceptual provisions for structuring the prerequisites, challenges and drivers of digital transformation of domestic business structures, which provide for the division into external and internal, reflecting the possible effects of the implementation of relevant drivers of digital transformation of enterprises; system of global statistical indices of development of digital economy of the country; a system of specific recommendations for raising the level of the Digital Business Transformation Index, which takes into account the specifics of each respondent in general and takes into account current changes in the functioning of its business processes; identification of stakeholders from the standpoint of the impact of digital economy processes. Scope: enterprises of different spheres of activity.
