Currently, socially oriented nonprofit organizations (SO NPOs) in Russia are actively engaged in the process of social services provision. The support provided to them, including the financial support provided by the regional authorities, is extremely important for SO NPOs. This article describes the reasons why the state involves NPOs in social services provision and gives them support, and the advantages and disadvantages of NPOs in services provision. We analyze the size, structure and dynamics of financial support for nonprofit organizations at the regional level and factors related to the size of support, as well as the criteria for granting subsidies (one of the types of support). The criteria were analyzed based on the regional legislation of 52 regions of Russia. The analysis of the size, structure and dynamics of financial support was conducted on the data from registers of SO NPOs that received support of 43 regions of Russia for 2016-2018. Our analysis demonstrates an increase in the total amount of support and a significant intraregional and interregional differentiation in the size of support. Using the method of ordinary least squares, we found that the average per capita value of financial support provided to the SO NPOs at the regional level is positively associated with per capita regional budget revenues, the share of education expenditures in the total amount of regional budget expenditures and the quality of life in the region.
