Research On Bidding Strategy And Bidding Mechanism Under Game Theory Model

The present about main achievement of bidding is concentrated on the decided theory. Based on game model in bidding and auction theory, this paper from game theory deeply researches the bidder's strategy and bidding mechanisms for the employer in a systematic way. The main contents and achievement of the dissertation are summarized as follows:(1)Based on the model of the Independent Private Value Model(IPVM) ,the model is extended to take account of the following cases: bidder are risk averse,bidder are asymmetric, the influence of collusion among bidders may occur probably during bidding, then both qualitative and quantitative conclusions are obtained. The problem that lend to the limit of auction model can be solved effectively and these discussion can further the auction model to conform to reality in some degree.(2) The primary work of this paper focuses on the bidding behavior when there is collusion among bidders. From effectiveness and incentive compatibility point of view, three cartel mechanisms are analyzed, then it discusses the cartel mechanism and advances a theoretical model of cartel bidding behavior in case of difference the sealed auction; At mean time, the two strategies are presented when the employer face the bidder's collusive behavior, the two strategies can deal with collusion effectively.(3) Research on the important factor which will influence auction mechanisms is conducted based on the optimal mechanism theorem, the best auction mechanisms has changed under these different circumstances; By this base, the sealed second-bid auction is deeply discussed, then the conclude is advanced: this auction mechanisms is more effective than the sealed first-bid auction, this mechanism is an effective and practical mechanism. Lastly how to carry out in practice has been studied.(4) About the optimal construction contract of this paper breaks through a traditional incentive contract. Best construction contract is presented by based on change order in implement stage because change order can result in increase of implement costs and loss of ex post inefficient renegotiation under asymmetric information,Considering the transaction cost during the procedure of contract implementation, the employer's optimal contract model with the minimum total cost for whole procedure is founded quantitatively and qualitatively, It can help the employer to choose the contract at bidding stage.(5) The bidding games model and Nash equilibrium strategy are established based on the lowest price in bid. And in china compound reservation price is generally offered in project construction, the bidder's strategy is also studied in such a situation. Bidder's bidding strategies under these models are drawn; this can help the bidder make their decision more scientifically and rationally.
