The work is dedicated to the analysis of the economic nature of public-private partnerships (PPP) and the need to create conditions for attracting private investments through the provision of various government guarantees. First and foremost, the economic aspect of PPP is analyzed in order to identify the key factors in attracting a private sector partner to a project. Subsequently, the potential risks associated with implementing PPP initiatives and methods to mitigate them are examined. It is noted that the PPP model is of significant importance as it allows for the attraction of not only private capital for the construction of socially beneficial projects, but also expertise in managing long-term investment cycles. Special attention is paid to such government guarantee mechanisms as the "Investment Protection and Promotion Agreement" and the "Reciprocal Investment Contract". The issues of increasing the involvement of the private sector in socially significant projects is a relevant topic, as the higher the level of involvement of the private partner, the greater the economic and social impact the project will have.
