This study explores the interaction between the driving factors that affect value for money in the PPP model and their respective importance proportions. It combines the literature analysis method and the Delphi method to construct an index system, uses the analytic hierarchy process to calculate the weight of the driving factors, and adopts decision-making The laboratory method was used to construct a comprehensive influence matrix and calculate centrality. The results show that the comprehensive impact of reasonable risk sharing, recognition of stakeholders, organizational and operational capabilities, long-term contract, full life cycle costs, and government control of prices is relatively high.
