FINANCIAL AND DIGITAL ARCHITECTURE FOR INTEGRATING PUBLIC-PRIVATE PARTNERSHIPS INTO THE PUBLIC PROCUREMENT SYSTEM

Abstract

The article develops a financial-digital architecture for integrating Public-Private Partnership (PPP) mechanisms into the public procurement system, based on the synthesis of risk management tools with a digital ecosystem for monitoring the life cycle of infrastructure assets. A system for evaluating integration performance is constructed, grounded in the combination of functional blocks: financial modeling of the Weighted Average Cost of Capital (WACC), algorithmic monitoring of KPIs via IoT platforms, probabilistic stress-testing of fiscal risks (FRAT), and the regulatory framework for institutional transparency. The study facilitates a transition from the isolated assessment of tender procedures to the analysis of PPPs as verified investment assets, which has allowed for the identification of the "digital trust premium" effect and its impact on reducing borrowing costs. The author develops a methodological approach to evaluating PPP financial efficiency by introducing a Digital Maturity Index (Idm), which ensures dynamic adjustment of the discount rate in NPV models, accounting for the level of information transparency. A methodological toolkit for stress-testing contingent fiscal liabilities is proposed, involving sequential evaluation stages: from the decomposition of risk premium components to virtual capital provisioning within the public financial management system. This ensures the practical implementation of a proactive debt management model, minimizing "fiscal shocks" and achieving financial convergence of public procurement with the requirements of international institutional investors. The necessity of transforming the Prozorro system into a financial-analytical hub capable of providing continuous access to verified data for the automation of budget payments is justified, as this is a key condition for enhancing Ukraine's investment attractiveness in the context of post-war recovery.
