摘　　要：公私合作(PPP)模式可以有效缓解地方政府财政压力,化解地方政府财政风险,然而PPP项目的长期性、复杂性等决定了其面临着繁杂多变的风险因素。合理的风险分担机制是PPP项目规范运行的前提,也是公共服务满足公众诉求的有力保障。通过建立PPP项目风险分担动态博弈模型,得出了对应的子博弈精炼纳什均衡解,并以长春市城区地下综合管廊项目为例,通过问卷调查获取相关博弈影响因子,根据博弈模型求出政府部门与社会资本方的风险分担比例,分析了参与双方在地位不对等情况下的风险分担和风险转移情况。The public-private partnership(PPP)model can effectively alleviate the financial pressure and resolve financial risks of local government.However,the long-term and complex characteristics of PPP project determine that it faces various and variable risk factors.A reasonable risk sharing mechanism is the prerequisite for the standardized operation of PPP project,and it is also a powerful guarantee for public services to meet public demands.A dynamic game model of PPP project risk sharing was established.Then the corresponding sub-game refined Nash equilibrium solution was obtained.Taking the underground utility tunnel project in Changchun City as an example,the relevant game influence factors were obtained by questionnaire survey,and the risk sharing ratio between government department and social capital parties was obtained according to the game model.The risk sharing and risk transfer between the two parties were analyzed under the condition of unequal status of participants.
