Abstract: The relevance of the study is determined by the lack of understanding of a certain system of financial regulation of social innovations, which does not allow to ensure the targeted orientation, stability and fullness of financial flows within the framework of the implementation of socio-innovative projects and financing of social innovations throughout their life cycle, which can qualitatively affect chronically unsolvable problems that hinder the improvement of social security of society and the state. The purpose of the article is to formulate an approach to the formation of an effective system of financial regulation of social innovations in order to ensure the social security of the state. The research methodology is based on the developments of Russian and foreign scientists in the field of social security, social innovation, financial regulation. Methods of generalization, analogy, statistical data analysis, tabular and graphical methods of information interpretation were used. The paper presents approaches to the concept and content of the concept of "social security"; the results of the author's calculation of indicators of social security of the Russian Federation in modern conditions by the index method, taking into account existing scientific developments, strategic planning documents, as well as publicly available statistical data; conceptual elements and approaches for the formation of an effective system of financial regulation of social innovations, based on the requirements of achieving social security. There are two types of financial regulation of social innovations (operational and strategic), levels of implementation (micro-regulation, mesoregulation, macro-regulation), the nature of the impact (stimulating or restrictive), forms of regulation (direct and indirect).
