Research On The Formation And Control Of The Grey Interest Chain Of Bidders And Bidders Of Government Investment Projects

The project invested by government has the characteristics of large investment,large profit margin and stable profit,and the bidding subject easily produce collusion behavior driven by the interests.The most prominent of which is the collusion between the bidder and the bidder.The bidders and bidders are prone to generate gray interest chains for the pursuit of project interests,which seriously damages the interests of other bidding entities,undermines the healthy development of the bidding market,and reduces the benefits of government investment.Therefore,the tender interest of bidders and bidders is studied.The formation process and control of the chain have certain necessity and urgency.The main research work of the thesis is as follows:Firstly,it analyzes the related concepts,contents and characteristics of government investment projects,project bidding,gray interest chain,etc.,and innovatively puts forward the basic concept and framework of the gray interest chain of bidders and bidders of government investment projects.The analysis of the chain formation process provides a theoretical basis and ideas.Secondly,it analyzes the three stages of interest creation,benefit distribution and benefit realization in the gray interest chain of bidders and bidders,and establishes the pre-selection of gray interest chain nodes through questionnaires,expert consultation methods and case analysis.The reliability and validity analysis of SPSS 19.0 software is used to determine the main nodes in each stage.Based on the time and space and logic analysis of the nodes,the main process map of the gray interest chain of the bidder and the bidder is obtained.Thirdly,the node identification method is combed and compared,and the three nodes identification methods of median centrality,degree centrality and near centrality are integrated to construct a cosine similarity model,which overcomes the problem of singleness of node recognition angle.The group weighting method is used to derive the interest chain node distance,and the interest chain cosine similarity node identification process and node level are designed.Based on the specific typical case,the importance degree of each node of the gray interest chain is obtained.Finally,according to the analysis of the identification results,the corresponding control measures are proposed from four aspects:increasing the monitoring and punishment of interest chain,establishing the resource integration and cracking mechanism,increasing the difficulty of implementing the benefits realization measures,and strengthening the audit work after winning the bid,in order to effectively prevent the bidders.With the formation of the gray interest chain of bidders,it will reduce the collusion behavior of government investment projects and promote the "open,fair and just"atmosphere of the bidding market.Based on the vertical collusion of government investment projects,this paper studies the formation process and control measures of the gray interest chain between the bidders and bidders of government investment projects,enriching the vertical collusion behavior and govermance mechanism of government investment projects.The research content makes up for the research on the specific formation process of the gray interest chain of bidding,and provides ideas for the management of the gray interest chain of bidders and bidders.
