The relevance of the study is conditioned by the need to improve the main forms of social security and social guarantees at the national level, in accordance with the current legislative and regulatory support, state target programmes, and existing infrastructure. The purpose of the study is to define modern areas of institutional support for social innovations for the balanced development of socio-economic systems. General scientific theoretical methods, in particular analysis, synthesis, and generalisation, were chosen as the leading research methods. It is determined that the basic foundations of state support are the provision of the institutional development of innovative infrastructure and interaction of civil society with state and regional authorities and local self-government. It is established that a necessary prerequisite for the promotion of social development and the introduction of social innovations is institutional support at the national level, which will coordinate the implementation of social initiatives that can later be produced as social innovations. Therefore, the imperatives of the development of the social component are defined as social innovations that are characterised by non-standard, but effective solutions to social problems, the priority of which is the social (qualitative), rather than the economic (financial) effect. The diversity of areas of social activity of the Ministry of Social Policy and heterogeneity of ways of its interaction with civil society are revealed. It was found out that programme-targeted conceptual fields, activities, and programmes to promote the development of social innovations at the national, regional, and local levels are currently absent, but the main interest in a wide range of manifestations of social innovations and the possibility of attracting funds to finance them belong to the initiatives of non-governmental organisations and social entrepreneurship. Accordingly, it is confirmed that the main institutional structure that can support the processes of generating, producing, and distributing social innovations is the Ministry of Social Policy of Ukraine, respectively, at the regional level, such structures can be local state administrations. The practical significance of the study is conditioned by the establishment of a theoretical basis for the chosen goal for further implementation in practice.
