The main objective of this study is to investigate a superior method of evaluation, to accurately assess the investment value of infrastructure PPP projects, and to compile literature for the development of infrastructure PPP projects. To accomplish this, we propose a comprehensive approach that involves calculating the PSC value and PPP value for a thorough analysis. This analysis aims to determine whether the PPP model should replace the government’s traditional investment and operational approach. Secondly, an analysis of VFM and PSC is conducted at the beginning of the project, and thirdly, a continuous dynamic evaluation of VFM + PSC is implemented throughout the project lifecycle. The results indicate that developing more targeted project implementation strategies in the planning stage and conducting continuous dynamic evaluation throughout the life cycle, the integration and application of VFM and PSC in infrastructure PPP projects can improve the accuracy and objectivity of evaluation, reduce project risks, enhance cooperation between the government and enterprises, provide stronger support for the implementation of projects, promote the development of the PPP model, and enhance the efficiency of public resource utilization. This approach is expected to be increasingly valued and applied in PPP projects in the future.
