The article contains the results of research on the main determinants of management capacity (MC) and its financial support. Identifying their features in accordance with the level of development of the digital economy allows us to draw conclusions about the priority areas of personnel development, information and innovation support for management decisions and the development of corporate culture and teamwork. The components of management capacity must meet the strategic objectives of the enterprise. Priorities for the implementation of management innovation and investment projects for the development of management capacity are determined depending on the impact of each component and the overall level of management capacity. Similarly, the need for financial support for each component of the MC is determined. The contradictions in assessing and prioritizing are the interrelationships of the components, as well as the duplication of development functions. Development of management capacity in the conditions of informatization and intellectualization of economy, introduction of innovations at the enterprises is carried out in the environment of corporate culture. Corporate strategic management in the digital economy involves the use of a comprehensive and targeted management system and environmental information support for management activities. Reasonable choice of determinants with the help of human-oriented value approach is presented in theories and practices of using a system of balanced scores, maximizing value for owners, visualization of development maps and more. The law of synergy allows to obtain new qualities of management capacity based on the development of each component and their relationship. This connection is carried out in accordance with the main carrier of management capacity - the manager, who is also a carrier of corporate culture, innovation and an active user of the information system of the enterprise and a team player. Such various roles of the manager and the purpose of development of his or her personal potential as the expert and the person demand the complex approach to formation of components of management capacity of the enterprise. At the heart of the components and as the component with the greatest equal capacity is the management capacity of personnel (MCP) at all levels (from enterprise to individual). In accordance with the MCP, innovative, informational, team, cultural and corporate potentials are considered. Determinants of management capacity development should be based on key determinants of value in accordance with each of the components and stage of the life cycle of the enterprise. This will determine the priority aspects of management capacity development, identify the links between its components, their interaction and the dynamics of determinants of management capacity development in accordance with the determinants of strategic management of the enterprise. It is also important for the digital economy to use the potential of information systems, electronic communications, digital skills of personnel. Determinants of financial support are evaluated as the indicators of innovation and investment projects; introduction of changes in management; improvement of the information system, corporate system of the enterprise, personnel training costs, support of departments in certain areas, personnel management system costs, personnel incentives and motivation in terms of direct costs and efficiency, as well as in terms of saving resources: time, human and material resources. The current system of monitoring, evaluation and forecasting of interrelated financial and non-financial determinants, combined within the framework of human-oriented value management, allows to assess the state of management potential and identify components that need to be developed at first instance.
