【摘要】 在政府和社会资本合作(PPP)模式下，完善邻避设施项目的风险分担机制有助于项目的顺利实施。从政府和社会资本两个角度，基于风险识别和风险分担博弈模型进行了初步博弈研究，判定风险分担方法和影响双方风险分担的因素，并进行了项目风险分担比例的博弈求解。同时，基于讨价还价博弈模型分析了双方风险分担比例，并在包括银行、项目监理方、项目承包方等多个主体的社会资本内部建立联合体模型，进一步探究社会资本各方的风险分担比例。研究结果表明，在初步风险分担过程中，影响风险分担比例的因素主要是参与方的风险偏好和风险承担能力，但参与项目的社会资本对风险的偏好度也会影响风险的分担比例。未来应进一步完善邻避设施PPP项目的相关法律法规，建立合理的风险分担机制；并积极协调政府和社会资本双方的利益，追求社会和经济的双重效益；与此同时，还应增加项目参与方信息的对称性，提高社会资本的公平感知，以及完善政府与社会资本的约束机制和监督评估机制。更多还原

【Abstract】 Under the PPP model, improving the risk-sharing mechanism of NIMBY facilities projects can help the smooth implementation of the projects. Based on the risk identification and risk sharing game model from both government and social capital perspectives, a preliminary game study is conducted to determine the risk sharing method and risk sharing factors of both parties, and the game solution of the project risk sharing ratio is conducted. At the same time, based on the bargaining game model, the risk sharing ratio between the two parties is analyzed, and an internal social capital consortium model is established among the social capital, including banks, project supervisors and project contractors, and the risk sharing ratio between the social capital parties is investigated. The research results show that in the preliminary risk sharing process, the factors that affect the risk sharing ratio are mainly the risk preference and risk bearing ability of the participants, and the risk preference of the social capital involved in the project also affects the risk sharing ratio; the relevant laws and regulations of NIMBY facilities PPP projects should be further improved in the future, and a reasonable risk sharing mechanism needs to be established; coordinating the interests of both government and social capital, the pursue both social and economic benefits, increase the symmetry of information of project participants, improve the fairness perception of social capital, as well as improve the constraint mechanism and supervision and evaluation mechanism of government and social capital.更多还原
