The article examines the role of investment project as a key instrument for stimulating development projects of socio-economic development of region systems. It analyzes theoretical approaches to defining the essence of investment project, its classification, and main areas of implementation in a regional context. It identifies factors affecting the effective use of budget resources, mechanisms for attracting additional financial flows, and the impact of the institutional environment on the effectiveness of investment programs. Particular attention is paid to the interaction between the state, local government, and business in shaping the investment climate. An analysis of existing experience in attracting and using public investment has been carried out. Examples of positive practices in regional investment policy are given and the risks of its implementation are outlined. Methodological tools for evaluating effectiveness, a strategic planning model, and a system of monitoring indicators are proposed. Key channels of influence (infrastructure, human capital, innovation, support for small and medium-sized businesses) are substantiated, and the risks of project implementation and mechanisms for their minimization are identified. Ten key steps for implementing the strategic planning model for public investment (from analyzing regional needs to the final assessment of best practices) are proposed. The recommendations to authorities on prioritizing, preparing, and evaluating investments, as well as the parameters for introducing public-private partnerships and mixed financing, are of practical importance. The results of the study emphasize that investment project is not only a financial but also a strategic resource for increasing the competitiveness of regions and ensuring their sustainable development.
