Research On The Change And Control Method Of The Degree Of The Procurement Information Asymmetry

With the increasingly fierce market competition, the enterprise gradually realize the importance of procurement procedures for enterprise procurement procedures of scientific, effective management, to reduce enterprise procurement costs, improve enterprise's profit ability, promotes the enterprise purchase turnover, and to enhance the core competitiveness of the enterprise itself guarantee. But most of the enterprise are not will purchase link standing in a the point of view of system for research between buyers and suppliers of information between game, it is based on the enterprise procurement system information asymmetry problem related research. This paper mainly choose to have periodic mobile phone industry, on its core components procurement as a typical background, With system detailed research to the enterprise procurement system.First of all, between buyers and suppliers from the aspects of the release of information and communication process, and enterprise to suppliers of information of the collection of buyers, and gives the procurement system purchasing information asymmetry related definition definition, introduced the forming mechanism of information asymmetry, and gives the degree of information asymmetry and product information asymmetry degree quantitatively.Secondly, in the information asymmetry theory, and on the basis of the study of purchasing information asymmetry degrees dynamic change, it is concluded that the purchasing information asymmetry in the purchase of different phases of the life cycle curve and the regional change. A systematic analysis of the purchasing all phases of the product life cycle curve and its property, in considering purchasing products quality information asymmetry degrees and price information asymmetry degrees basis, it is concluded that the purchasing products information asymmetry degrees curve changing trends. Also, according to the purchasing information asymmetry dynamic change trends of degrees, and purchasing information asymmetry of the formation mechanism of degrees, and further analysis and put forward the purchasing information asymmetry degree of control method. And at the same time, to purchase as a system to analysis, combed the procurement system variables and variable relationship; Through the analysis of purchasing system is a complex that the social system, using special SD software Vensim construction purchasing system SD causality diagram, and further constructs the procurement system SD general model. Use of procurement system software SD information asymmetry degrees control method was simulation.Finally, the selection of the typical is cyclical mobile phone industry, on its core components procurement as a typical background, through to the basic data gathering, to construct the procurement system equations number, and purchasing systems of the validity of the model for inspection. At the same time for the purchasing information asymmetry degrees control method of price, quality, product from three aspects, the simulation control, through to the control variables to find out some of the information asymmetry in the influence of degrees, so as to better improve purchasing the system to provide the strong theoretical support.
