拍卖是通过确定拍卖品价格而实现交换的一种商品交易方式。本文在对利益主体追逐利益的分析基础上,通过对竞价中的偶然性的研究,试图说明偶然性不仅是确定价格一般性因素的补充说明,而且软化了将价高者得作为目标追逐的坚硬动机。文章还论证了偶然性与它背后的价高者得规则如何交替发挥能量,影响拍卖品价格的形成。 An auction is a form of trade in commodities that is exchanged by determining the price of an auction item. Based on the analysis of the profit-seeking interests of the stakeholders, this article tries to show that the contingency is not only a supplement to determine the general factors of price, but also softens the hard-line motivation of using the highest bidder as the target chase. The article also demonstrates how the contingency and the law of the highest bidder behind it can alternately exert their energy and influence the formation of the price of the auction item.
