The article examines the prospects for the development of Ukraine’s innovative infrastructure in the conditions of the digital economy, and solves the problems of ensuring the effectiveness of its functioning. The current legislation of Ukraine in this area, international legal acts, scientific works have been analyzed, conclusions have been drawn that have both theoretical and practical significance regarding the outlined issue.

At the same time, solving the problem of the competitiveness of scientific research and scientific and technical (experimental) development in modern conditions is impossible without the integration of the scientific and innovative system of Ukraine into the European Research Area – a system of programs and political instruments that unites the institutional environment of research and development of the states that are members of the European Union and associated members for the purpose of development of international scientific and technical cooperation, free transfer of knowledge, mobility of researchers. Conclusions and prospects for the development. Summarizing the above, it should be noted that in the conditions of the digital economy, one of the priority tasks of modern state policy is the formation and ensuring the functioning of a stable innovative infrastructure, in particular, the creation of the necessary organizational, legal and financial conditions for the development of the research infrastructure system, promoting the integration of the scientific and innovative system of Ukraine to the EDP, the development of «digital infrastructures», in particular, e-infrastructures, the accession of Ukraine to the Single Digital Market of the EU, the adaptation of higher education to the European Higher Education Area.
