Research On Governance Mechanism Of Conspiracy Behavior In Engineering Project Bidding

The implementation efficiency of engineering projects in China has been greatly improved since the 1980 s,when China began to conduct project bidding and tendering.Especially after the "law of the People's Republic of China on tendering and bidding" was formally implemented in early 2001,China's bidding system entered into a new stage of development under the condition of market economy.The system of bidding not only brings great benefits,but also causes a series of corruption problems to the bidding market.Due to the lack of effective supervision over the fairness of bidding,a great deal of bidding works are still in a mere formality to a large extent.In most projects,multiple participants always conspire,deal privately and operate secretly.Therefore,based on the background of the current national efforts to promote the construction of infrastructure,this paper studies the common bidding and bidding collusion behavior.The basic structure of bidding market governance mechanism is constructed and the governance methods of bidding market are put forward from various aspects.First of all,this paper analyzes the main participants in bidding activities,the types of collusion among these participants and the common forms of collusion.Based on collusion theory,the internal and external causes of collusion in bidding activities are discussed.Secondly,this paper constructs the game model of collusion alliance and governmental supervision institution.Based on the game theory,this paper analyzes the conditions of collusion alliance to choose conspiracy and the conditions of government supervision to choose supervising.By solving the evolutionary game model,this paper analyzes and obtains a evolutionary stabilization strategy of the system which is composed of collusion alliance and governmental supervision,and simulation software was used to simulate the dynamic process of system replication.For the imperfect evolutionary stability strategy,according to the jacobian moment judgment method,the parameters that need to be modified are found out in order to achieve the ideal evolutionary stability strategy,and the simulation software is used for simulation verification,so as to analyze the factors that affect the occurrence of bidding collusion behaviors.Finally,by comparing and referring to the social governance contents which insist of source governance,legal governance,system governance and comprehensive measures,this paper proposes a bidding market governance mechanism centering on the bidding system and legal mechanism and including the information disclosure mechanism,supervision mechanism and incentive and constraint mechanism.This paper discusses the governance scheme of bidding collusion in terms of law,source,system and comprehensive measures from many aspects,which solves the problems of asymmetric information,incomplete supervision and weak law enforcement in bidding market.This governance mechanism has certain reference significance and reference value for the engineering bidding to avoid collusion.
