中文摘要：	自我国从2000 年开始执行《中华人民共和国招标投标法》以来,招投标市场的竞争逐步走向规范化、法制化、有序化的轨道。然而,大量案例证实招投标的合谋现象如围标和串标等违法行为, 已严重干扰正常的市场竞争秩序。本文针对招投标决策内容进行梳理，通过对围标和串标的行为进行区别界定和招投标的理论和评标方法进行分析，将博弈论的相关方法引入，建立基于不同评标方法下的围标、串标的行为博弈模型, 通过求解模型，对模型参数和敏感性分析,得到影响围标和串标的行为关键参数和相互关系。影响围标的关键因素是投标人的围标溢价预期收益、正常竞争收益，围标败露的处罚力度和参与投标竞争者的总数这四个参数，与“围标团体”的数量，陪标成本等参数无关。其中围标溢价预期收益和投标竞争者数量与围标的行为是正相关关系，正常竞争收益与围标败露的处罚力度与围标的行为是负相关关系。影响串标的关键因素是招标人的串标预期收益，正常招标收益和招标人串标败露处罚这三个因素有关，与参与串标的投标参与人数和处罚无关。其中串标预期收益与串标的行为是正相关关系，正常招标收益和招标人串标败露的处罚力度与串标的行为是负相关关系。论文在上述分析的基础上，通过对相关围标和串标案例的讨论，提出治理围标和串标行为的关键措施如设置合理的拦标价，合理设置检查成本与处罚费的比例、加强对报高价投标人的检查等措施, 为我国招投标管理者和监督者对围标、串标的行为治理，提供有益参考。
英文摘要：	Since China began the implementation of "The people's Republic of China, the Tendering and Bidding Law" from 2000, the bidding competition in the market gradually standardized, legal, orderly track. However, a large number of cases confirmed bidding collusion phenomenon such as Surround-Bidding and forging bid, has been seriously disturb the normal order of market competition. According to the study on bidding decision strategy and the analysis on bidding theory and evaluation methods of bidding, this article define the behavior of the surround-bidding and forging bidding. Based on the relevant methods of game theory, the author establishes the behavior game model under different evaluation methods based on illegal bidding, by solving the model, the parameters of the model and sensitivity analysis influence of key parameters and the bidding behavior and internal relationship. The four key factors affecting the surround-bidding is bidding premium expected return, normal competitive return, the penalties and the number of the participant in bidding. The number of "surround-bidding group" and cost of accompanying bidding unrelated to surround-bidding. The bid premium expected earnings and the number of the participant in bidding are positive correlation to surround-bidding, penalties and bidding normal competition returns are negative correlation to surround-bidding. The three key factors affect the forging bidding are the expected return of tenderee, normal bidding returns and the penalties to forging bidding. No relevant with the number of the tenterers participating in forging bidding and string out punishment. The expected return of tenderee is positive correlation to the forging bidding behavior; the tenderee’s profit in normal bidding and the penalties to forging bidding are negative to forging bidding. Based on the above analysis and the discussion about the related bidding and string case, the article proposes the key measures to control surround bidding and colluding behavior such as setting a reasonable price bar, a reasonable set of inspection cost and penalty fee proportion, strengthen measures to quote price the bidder's check. Provide a useful reference for the management of bidding and supervisor of illegal bidding behavior management.
