Application　of　the　game　theory　in　construction　can　make　the　bidding　decision　more　scientific.　However,　many　existing　game-based　bidding　quotation　models　are　based　on　the　hypothesis　of　risk　averse　tenders,　which　does　not　conform　to　the　construction　condition.　To　better　fit　the　project　bidding　reality,　it　is　necessary　to　consider　the　bidders＇　(or　players＇)　risk　attitude.　This　paper　establishes　the　bidding　quotation　game　model　under　the　bill　of　quantities　with　the　comprehensive　evaluation　method　by　introducing　the　risk　factor　representing　the　bidders＇　risk　attitude,　derives　the　equations　of　bidding　relation　and　its　iterative　algorithm,　and　analyzes　the　bidding　strategies　and　effects　of　bidders＇　risk　coefficients　on　optimal　bidding　quotations.　Analysis　of　a　real　case　shows　that　the　implication　of　the　game　model　in　bidding　quotation　can　lead　to　an　improvement　in　the　probability　of　winning　the　bid.　And　the　proposed　game　model　has　its　superiority,　which　may　provide　a　support　of　methods　for　real　bidding　decision　making.　©　2018,　Editorial　Office　of　Control　and　Decision.　All　right　reserved.
