摘要:
以网络拍卖中的虚假出价行为为研究对象,在拍卖理论中的信息关联价值假设下,运用函数型数据分析方法并基于竞拍者随机到达的非齐次泊松过程特征,构建了卖者虚假出价动机阶段变化模型,对卖者参与虚假出价动机及影响进行分析。 研究结果表明,卖者的虚假出价参与动机随着拍卖的进行逐渐减弱,拍卖方式、关联程度、竞拍者人数以及拍品价值均会影响卖者参与虚假出价的动机。 其中,第二价格密封拍卖下卖者参与虚假出价的动机更强烈;关联程度越高的拍卖中更易发生虚假出价;竞拍者人数的增加则会减弱卖者的参与动机;拍品价值中个人估值占比越小,则越易发生虚假出价。 最后通过实证分析验证了所得结论并给出具体管理启示,为进一步设计网络拍卖机制以减少虚假出价行为的发生、维护网络交易公平公正、提升拍卖市场运行效率具有实践意义。
Abstract:
We use functional data analysis method to study the motivation and influence of bidding behavior under the assumption of in鄄formation-related value in auction theory,and construct a model of seller bidding motivation stage change based on the characteristics ofnon-homogeneous Poisson process of random arrival of?
bidders, and analyze the seller ’ s motivation and influence to participate inbidding. The results of the study show that the seller’s motivation to bid gradually?
decreases as the auction progresses,and the auctionmethod,the degree of association,the number of bidders and the value of the lot all affect the seller’s?
motivation to participate in thebidding. Among them,the seller’s motivation to participate in the bid under the second price seal auction is stronger. The more relevantthe auction,the more likely it is to make bids. An increase in the number of bidders will weaken the seller’s motivation to participate.The smaller the?
proportion of individual valuations in the value of the lot,the more likely it is that bids will occur. Finally, throughempirical analysis,the conclusions obtained are?
verified and specific management enlightenment is given,which is of practical significancefor further designing the online auction mechanism to reduce the?
occurrence of bidding, maintain the fairness and justice of online transactions,and improve the operational efficiency of the auction market.
