At the same time, research into the nature of the origin of capital has shown that no single form of capital dominates. The successful combination of all forms of capital leads to the emergence of digital innovations, which, in turn, contribute to the formation of digital competencies at the level of economic entities and their implementation in the justification of management decisions. It is noted that these processes underlie significant changes in the promotion of innovative products and information and communication technologies in developed and developing countries. It has been proven that an unfavourable institutional environment stands out as the main reason for the slowdown in the digitalisation of the Ukrainian economy and the consolidation and concentration of business capital. Given this, there is a pressing scientific interest in the rationale, development and solutions in the digital economy with appropriate institutional support from state policy to improve the structure and quality of capital. The focus is on the peculiarities of the formation of digital business structures, in particular platform-type structures, as well as on the institutional design that determines the rules for the consolidation and concentration of capital in such structures. It has been found that digital technologies are changing the very nature of business structures and their behaviour in virtual life, with a transition to digital platforms, virtual business mobility and data exchange as a new form of capital. This is evidence that the digital economy is transferring capital and the activities of business structures from the real to the virtual world. The object of this study is the consolidation and concentration of capital, and the subject of the study is the essential characteristics of the digital economy, the institutional design that determines the rules of capital consolidation and concentration, and methods of managing them. Methods for managing the processes of capital consolidation and concentration are outlined, taking into account the specifics of the formation of digital business structures. The impact of new digital technologies on the consolidation and concentration of capital to ensure the financing of innovative renewal and restructuring of the economy is shown.eninstitutional designinstitutional developmentcapitalcapital consolidationcapital concentrationdigital business structuresmergers and acquisitionsmanagement methodsінституційний дизайнінституційний розвитоккапіталконсолідація капіталуконцентрація капіталуцифрові бізнес-структуризлиття та поглинанняметоди управлінняCapital consolidation and concentration in digital business structures: institutional design and management methodsКонсолідація та концентрація капіталу в цифрових бізнес-структурах: інституційний дизайн та методи управлінняArticle
