Research On Decision Model Of Bid Evaluation For Quality Price Elasticity Curve Based On Product Heterogeneity

From the perspective of economics,the essence of bidding procurement is a matching process between the bidding project and the high quality bidder.The tenderer hopes to satisfy his own needs through bidding and to maximize his utility.Bidders want to maximize their profits by bidding.The correct selection of bid evaluation method is not only related to whether the tenderee can get matched bidders through bidding,but also whether each bidder can fully embody his advantages and characteristics in the process.A correct selection of bidding evaluation method that accords with the maximization of the tenderee's utility and can fully display the competitiveness of the bidder is very important for both the tendering and bidding parties and the whole bidding project.However,the theoretical research on bid evaluation mainly focuses on policy,law,procedure and strategy,and the research based on its economic attributes is very few,especially the research on the decision of the suitability of the evaluation method based on the economic attribute of bid evaluation is even less.Although the relevant policies and regulations of our country have also made corresponding provisions on the reasonable and correct selection of bid evaluation methods for bid evaluation projects,these policies are often fuzzy to a great extent because of the lack of quantitative selection basis.Based on the theory of product differentiation,this paper takes the bidding evaluation of goods category with remarkable product difference as the main research subject,and takes the independent bidding and evaluation of enterprise goods category as the breakthrough point,and the applicability of the two main bidding evaluation methods: the lowest bid evaluation method and the comprehensive evaluation method,which are mainly used for reference by enterprises,are studied.Through the study of the economic attribute and evaluation mechanism of the two main bid evaluation methods,firstly defines the applicability of the two main bid evaluation methods from the qualitative point of view: when the non-price evaluation factors of the products or services offered by potential bidders are heterogeneous,that is,the difference of products is obvious,and we should choose the comprehensive evaluation method of product price and non-price;on the other hand,we should choose the lowest price evaluation method which is mainly based on price evaluation.Then,this paper definesthe non-price evaluation factors as the generalized quality evaluation factors,and constructs the quality price elasticity curve model by using the relevant theories of microeconomics and industrial economics.Based on the utility of the tenderer,the heterogeneity of the goods supplied by the potential bidder is quantitatively measured,and then the heterogeneity of the supply market within a certain range is quantitatively evaluated for the bidding items of the goods category based on the utility of the tenderer.Finally,the quantitative selection decision of the two main bid evaluation methods is completed.At the end of this paper,we validate the above bidding evaluation method selection model and evaluation criteria through the introduction of empirical cases,thus more specifically and clearly illustrate the feasibility and effectiveness of the model and its evaluation criteria in the selection of bid evaluation method.
