在Friedman對投標人數(shù)所作的服從Poisson分布假定的基礎(chǔ)上，研究了招標活動中招標商對最優(yōu)保留值的設(shè)置問題，得出了最優(yōu)保留值的設(shè)置與參與投標的期望人數(shù)無關(guān)以及招標商的期望收益受參與投標的期望人數(shù)影響的結(jié)論，同時給出了最優(yōu)保留值的設(shè)置公式，從而給招標機制的設(shè)計提出了一種更接近實際情況的方法。

Friedman viewed that the number of bidders in bidding submit Poisson Distribution. On the aboue assumption, this paper studies reservation value setting and draws conclusions that reservation value has no pertinence with the expected number of bidders while the expected number of bidders affect expected revenue of the auctioneer. Meanwhile this paper gets a formula to calculate reservation value, thus brings forward a way for design of bidding meechanism, which further approaches actual conditions.
