拍賣賽局在國際上逐年受到重視，主要是透過標案的活動，可以讓資源分配更加有效益外，對於社會發展有更好的幫助。因為透過招標的方式，可以篩選出優質的廠商，以提供更優質的產品或公共工程品質等，當然合理的價格也關乎到全民的利益。
本研究以一實際拍賣個案作為討論基礎，分別探討招標者的標案設計，以及競標者的出價策略。透過文獻的探討，了解各種拍賣競標的形式及其演進，而賽局元素分析的概念，協助了解各個參與者、標案規則及策略方案。同時，收益函數的計算與推導，提供較為理性的出價函數，並發現在不同秘密底價與不同出價次數機會下，產生不同的期望剩餘結果。最終，由分析結果發現，在多次出價機會的方式下，產生對於雙方皆有利的期望總剩餘結果。

Auction game theory is becoming popular gradually worldwide and a powerful tool for analysis of auction activity which can lead to more efficient on resource allocation and better contribution on society. Through bidding process, high quality of products and public constructions from the qualified suppliers are available which is related to benefit of citizen.
This study is motivated by a real auction case focusing on the design from auctioneer, bidding strategy of bidders. We restrict our attention to the variety of auctions and its development by literature studying and get more insights on players, rule and strategy through game theory concept. Eventually, we provide a rational biding function model by payoff function calculations and evaluate the differences of surplus from each player under the different bidding situations. Meanwhile, the result is like multi-round auction giving reciprocal l benefit to all players.
