Abstract
There are two main quotation mode in current bidding, which are without base price and compound base price. Bidders should bid accurately and reasonably to win a bid. Based on game theory and the characteristics in bidding, this paper constructed bidding price game model of without base price and bidding price game model of compound base price to provide evidence for bidding decision. Relevant factors of optimal bidding were found by analysing models results. The probability of bid winning can be improved by analysing these factors effectively. At last, the methods of preventing string bid phenomenon were proposed by comparative analysis of these two models.
