建设工程项目施工阶段参与主体管理行为三方演化博弈研究

Tripartite Evolutionary Game Study on Management Behaviors of Participants at Construction Stage of Construction Project Considering Corruption

施工阶段是建设工程项目全生命周期中最为关键的环节之一,腐败事件的发生将会引发项目质量下降、进度延误、费用超支等各类问题。为规范多方参与主体管理行为,构建施工单位、监理单位、建设单位三方参与主体的演化博弈模型,探究各方参与主体管理行为之间的相互影响。结果表明,建设工程项目管理行为三方博弈系统或存在一个渐进稳定点,增强建设单位奖励和惩罚力度及增加企业设租与寻租的合谋成本均有助于规范施工单位的生产行为。基于此给出3点建议:促进监理制度改革,推动行业转型升级;建立健全监督机制,优化项目监管成本;设置奖励惩罚机制,规范企业管理行为,从而最大程度地防范工程腐败。

The construction stage is the most important part in the entire project life cycle,and the occurrence of corruption will lead to various problems,such as quality degradation,schedule delays and cost overruns.In order to standardize the management behavior of multi-participant subjects,the paper constructs a tripartite evolutionary game model considering supervisors,owners and contractors.The interactions between the management behaviors of all parties involved are explored.The research results show that there may be an asymptotic stability point in the tripartite game system of construction project management behaviors.Enhancing both reward and punishment and increasing the cost of collusion between enterprises in rent setting and seeking will help standardize the production behavior of the contractors.Three suggestions are given based on the conclusion:Firstly,the reform of supervision system and the transformation and upgrading of the industry needs to be promoted;Secondly,the supervision mechanism to optimize the cost of project supervision needs to be established and improved;Thirdly,a reward and punishment mechanism to standardize the management behavior of enterprises is set up to prevent engineering corruption to the greatest extent.
