Abstract

This research presents a novel computational framework for analyzing financial risk allocation in public-private partnership (PPP) infrastructure projects through the lens of quantum-inspired optimization algorithms. Traditional risk assessment methodologies in infrastructure financing have largely relied on classical probabilistic models and Monte Carlo simulations, which often fail to capture the complex interdependencies and non-linear relationships between various risk factors. Our approach introduces a hybrid quantum-classical optimization model that treats risk allocation as a multi-dimensional optimization problem with entangled decision variables representing public and private sector risk exposures. The methodology combines quantum annealing principles with machine learning techniques to identify optimal risk-sharing configurations that minimize systemic financial vulnerability while maximizing project viability. We developed a computational model that processes 47 distinct risk factors across technical, financial, political, and environmental domains, capturing their complex interactions through quantum entanglement-inspired correlation matrices. The model was tested on a dataset of 128 historical PPP projects across transportation, energy, and social infrastructure sectors. Our results demonstrate that the quantum-inspired approach identifies risk allocation patterns that reduce overall project financial vulnerability by 23.7% compared to traditional allocation methods, while simultaneously increasing private sector participation willingness by 18.3%. The framework reveals previously unrecognized risk compensation mechanisms where certain risk transfers between public and private entities create emergent financial stability properties. This research contributes to both computational finance and infrastructure economics by providing a fundamentally new paradigm for understanding and optimizing risk allocation in complex public-private financing arrangements, with significant implications for sustainable infrastructure development and fiscal policy design.
