摘要
为确保通航安全和生态环境不受破坏的条件下合理利用河道砂石资源,基于一级密封拍卖独立私人价值模型探讨了采砂作业招标中最高控制价设置模型,并对比了不设控制价、设置但不公开控制价、公开控制价三种情况对投标人报价、招标人支付的影响。结果表明,不设控制价时,投标人的报价和招标人支付均最高;招标人公开控制价不仅降低了投标人的报价,且降低了招标人的支付。当招标人数确定时,招标人的支付随控制价的增高而增高;当控制价确定时,投标人数的增加将减少招标人的支付。最后提出了基于个人成本系数的招标最低控制价设置方法。
The sand mined in river is valuable materials in civil construction. It is an important issue for river course management agency to make sure navigation safety and protect ecological environment while mining the sand. In this study, the announced and secret highest control prices for bidding are discussed based on independent private values model in first sealed bid auction. This study shows that if control price is not concerned in the model, the quoted prices of the bidders and the payment of the buyers would be at the highest level; if the control price had been announced, the quoted prices of the bidders and the payment of the buyers would be reduced. When number of bidders is given, the payment of buyers would increase with control price. When the control price is give, the payment of buyers would reduce with number of bidders. Finally, the method of designing the lowest control price is proposed based on the cost index of individual bidders.
