Abstract

To address unbalanced benefit distribution, ambiguous risk sharing, and insufficient cooperation stability among governments, social capital, and project companies in infrastructure Public-Private Partnership (PPP) projects, this study optimizes multi-party cooperation based on cooperative game theory and the Shapley value method. First, it systematically identifies risk factors throughout the project life cycle and constructs a “input-risk-contribution-satisfaction” four-dimensional correction framework. Then, an improved Shapley value model is established, using the Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation to determine the weights and scores of correction factors for quantitative distribution of benefits and risks. Taking a provincial municipal road PPP project (total investment of 6 billion yuan, 20-year cooperation period) as an empirical case, the study compares the distribution results of traditional and improved models. Findings show the improved model increases social capital’s benefit share by 8.3%-12.5%, aligns governments’ and project companies’ risk ratios with their actual responsibilities, reduces cooperation default risk by 40%, and improves operational efficiency by 11.2%. This study provides a practical quantitative tool for infrastructure PPP cooperation mechanism design, contributing to the sustainable development of the PPP model.
