【摘要】：随着电子商务的迅速发展,人们的消费习惯有了很大改变,网上购物成为一种重要的消费方式,不同商务网站之间竞争日趋激烈,网上拍卖是电子商务的重要组成部分。由于现有拍卖方式层出不穷,不同拍卖方式的规则差异很大,研究最优网上拍卖机制设计对于买卖双方的决策极其重要。为此,本文以淘宝网现有拍卖机制为例进行建模,构建自下而上的multi-Agent仿真模型,研究不同拍卖机制设定对竞买人和拍卖人的最终收益的影响。主要工作介绍如下：(1)对现有与拍卖相关的研究进行归纳总结,分析其运行机制的不同之处,寻找网上拍卖常用的拍卖方式。(2)以淘宝网上拍卖实例为研究基础,考虑英式拍卖与荷兰拍卖两种常用网上拍卖方式来构建多物品网上拍卖模型,研究不同拍卖机制设计的优劣。(3)基于所构建的多主体网上多物品拍卖模型设计不同情景,对不同拍卖机制设计进行模拟和分析,根据模拟结果,可以得到以下两大结论：①相对于荷式拍卖,英式拍卖的出清价格更低,消费者收益更高,而生产者收益更低；②对于荷式拍卖而言,随着降价幅度的增加,达到出清价格、均衡消费者效用和生产者收益的速度越来越快,最终出清价格和生产者收益水平差异不大,而消费者均衡效用水平越来越高。模拟结果也表明了本文所构建的模型可为拍卖商选择最优拍卖机制提供借鉴,也为竞买者的竞价行为提供参考。
[Abstract]:With the rapid development of electronic commerce, people's consumption habits have been greatly changed, online shopping has become an important consumption mode, the competition between different business websites is becoming increasingly fierce. Online auction is an important part of electronic commerce. Due to the emergence of existing auction methods, the rules of different auction methods vary greatly. It is very important to study the design of optimal online auction mechanism for the decision of buyers and sellers. Therefore, this paper takes Taobao as an example to model the auction mechanism. The bottom-up multi-Agent simulation model is constructed. This paper studies the effect of different auction mechanism settings on the final income of bidders and auctioneers. The main work is as follows: 1. Based on Taobao auction examples, we consider two common online auction methods: British auction and Dutch auction to build a multi-item online auction model. This paper studies the advantages and disadvantages of different auction mechanism design. (3) based on the multi-agent network multi-item auction model to design different scenarios, the different auction mechanism design simulation and analysis, according to the simulation results. Two conclusions can be drawn as follows: 1: 1 compared with Dutch auction, British auction has lower clearing price, higher consumer income and lower producer income; 2 for Dutch auction, with the increase of price reduction, to reach the clearing price, the speed of balancing consumer utility and producer income is getting faster and faster, the final clearing price and producer income level is not different. The simulation results also show that the model constructed in this paper can provide reference for auctioneers to choose the optimal auction mechanism, and also for the bidding behavior of bidders.
