Due to growing global socio-economic and environmental challenges (population ageing, climate change, society polarization, etc.), there is a revaluation of a position and role of innovations in overcoming threats to social development in the modern world. Researchers note a shift in the innovation paradigm toward social innovation, since it is assumed that it is not possible to achieve a drastic improvement of the situation solely through technological innovations. At the same time, many existing problems cannot be solved with efforts of a single actor - intersectoral cooperation becomes a necessity. This aspect is of key importance for development of social innovation. The purpose of the study was to analyze development of social innovations in the Russian Federation based on an actor approach, which involves an overview of this phenomenon through the prism of activities of various entities and their interaction. General scientific methods were used in the study: discourse analysis, generalization, comparison, etc. Essential foundations and the role of social innovations in solving current society's problems are presented. Using the example of government structures, big business, and civil society, the authors explore the features of social innovation development in Russia. It is shown that development of social innovations depends on their interpretation in public discourse, involvement in strategies of various actors, and intersectoral cooperation in the innovation process. In conclusion, the prospects for development of studied phenomenon are determined within identified trends and the specifics of interconnections between designated actors. The results obtained may be used not only as an empirical basis for further research, but they may also represent practical significance in development of specific management decisions in this area.
