在分析项目主体之间博弈关系的基础上，建立了一般项目和政府投资项目行为主体三方之间的行为博弈模型，分析了博弈混合策略纳什均衡解。最后从建立完善的建设管理制度、事先监督机制与事后惩罚机制、激励机制与约束机制等方面提出了规范项目主体行为的具体对策。

The behavioural game model among the participants of general project and government investment project was established based on exploring the game relationships of the participants in construction project.Nash equilibrium of mixed strategy game was analyzed.Some countermeasures of resolving nonstandard behavior of participants in construction project such as building perfect system of construction management,the mechanism of supervision & punishment,the mechanism of incentive & constraint and so on were also presented at last.
