KEY ASPECTS OF THE INTERNATIONAL METHODOLOGY OF PUBLIC-PRIVATE PARTNERSHIP IN THE VECTOR OF SUSTAINABLE INFRASTRUCTURE DEVELOPMENT

Abstract

The article examines the methodology of public-private partnership in the international context as a comprehensive system of principles, procedures, and instruments that ensure the preparation, assessment, structuring, implementation, and monitoring of infrastructure projects involving the state and the private sector. It is substantiated that PPP should not be considered merely as a means of attracting private financing or compensating for the shortage of budgetary resources, since its effectiveness is determined by its ability to create long-term public value, ensure the quality of public services, provide optimal risk allocation, and maintain the fiscal sustainability of the state. The article explores international approaches to the development of PPP methodology, in particular the approaches of the World Bank, OECD, IMF, UNCITRAL, EPEC, and UNECE, which focus on sound public governance, transparency of procedures, competitive selection of the private partner, Value for Money assessment, fiscal risk management, and contract management throughout the entire project life cycle. It is shown that modern international PPP methodology is gradually shifting from a narrow financial and economic approach toward a broader paradigm focused on sustainability, inclusiveness, environmental responsibility, and consideration of the interests of public service users. The article proves that, for developing countries, the adaptation of international standards to national institutional, legal, financial, and socio-economic conditions is of particular importance. It concludes that effective PPP is possible only where there is an evidence-based methodology, professional state capacity, and a transparent risk management system.
