As an old price determining mechanism,auction technique is intensively used in the fields of project manage- ment.Even though auction economics provides a series institutional supply,there are many ventures at the field of pro- ject management such as bidder risk,bidder coherence risk,bidder moral hazard,invalid bidding method risk and pro- ject uncertainty risk.However,project and procurement bidding is a special auction activity.Because of its particularity and complexity,bidding activity of project management does not follow the roles of first sealed price auction or the sec- ond sealed price auction,in order to ensure the bidder's reasonable profit and secure the quality of project,quite differ- ently project bidding generally set bidding target,by access which the bidder can win the bidding.Thus auction informa- tion analysis is a very useful tool to control project cost,reduce construction risk and constrain the illegal action.By an- alyzing the distributing chart,relativity,bidding price and production scale,bidding price and productive ability of won enterprise,this article digs up possible problems at auction procedure.
