This paper aims to formulate a new PPP project public-participation mechanism that uses “public satisfaction” as a direct influencing factor in conjunction with the public-private benefit model to achieve a substantial response from project stakeholders regarding public satisfaction and ensure the transparency of PPP project operation. The proposed model, combined public satisfaction assessment with the principal-agent model, investigates the influence of public satisfaction on investors’ efforts and the benefit or risk distribution between the government and private investors. The results show that the public’s satisfaction level with the project directly affects the proportion of public and private income distribution, which provides a way for the public to directly play a substantive and positive role in PPP projects to guarantee public benefits and the smooth implementation. The increase in the public satisfaction evaluation of either the government or the investors, helps improve the overall effectiveness of PPP projects.

基于公众参与的PPP项目风险分配与收益分析

本文旨在建立一种新的PPP项目公众参与机制，该机制将“公众满意度”作为直接影响因素并结合公私收益模型，以实现项目利益相关者对公众满意度的实质性回应，并确保PPP的透明度项目运作。提出的模型将公众满意度评估与委托代理模型相结合，研究了公众满意度对投资者的努力以及政府与私人投资者之间的收益或风险分配的影响。结果表明，公众对项目的满意程度直接影响公共和私人收入分配的比例，这为公众提供了一种在PPP项目中直接发挥实质性和积极作用的方式，以确保公共利益和顺利实施。政府或投资者对公众满意度的评价的提高，有助于提高PPP项目的整体有效性。
