摘　　要：为了更好地发挥PPP项目中社会资本的运营管理优势,优化信息不对称下政府与社会资本的收益分配,充分分析社会资本的技术创新行为和机会主义行为,考虑代理方的两种行为成本和风险成本以及委托代理理论下激励与惩罚对项目总收益的影响,建立了基于委托代理理论的PPP项目激励机制模型。采用一阶条件法求解模型,得到了政府部门的最优激励与惩罚系数以及社会资本技术创新行为与机会主义行为最优努力水平;通过基于委托代理模型的最优解分析,得到了社会资本的风险感知度和两种行为能力分别对两种行为的努力水平以及项目收益分成的影响程度;通过对模型中的参数进行赋值,运用MATLAB软件进行数值模拟,对模型的结果分析进行了验证。研究结果表明,社会资本的行为能力与努力程度呈正相关。In order to exploit the advantages of operation and management of social capital in PPP projects better, as well as optimize the income distribution because of the information asymmetry between the government and the social capital, technological innovation and inhibit opportunistic behaviors are studied in detail. Considering behavioral cost and risk cost of two behaviors of the agent, as well as the influence in total income of incentive and penalty, an incentive mechanism model for PPP project is established based on the Principal-A- gent Theory. The optimal incentive and punishment coefficient of the government and optimal effort level of two behaviors of the social capital are obtained by calculating the model in first-order approach. Effect of risk perception and two behaviors abilities of social capital on effort level of social capital and income distribution are obtained by analyzing the optimal solution of the mode. The analysis results are verified by assigning parameters in the model and using MATLAB software for numerical simulation. The results show that there is a positive correlation between ability and effort level of a behavior and a negative correlation between the risk perception and effort level.
