本文以实证的方式研究了网络商品的价格离散程度 ,证明了由于互联网使信息在市场中呈现均衡分布 ,成本与价格的透明度被提高 ,从而网上商品价格也趋于收敛。在完全信息市场上 ,当信息获取成本极低或为零时 ,交易者反而减少了从事信息收集的积极性 ,信息搜寻者的搜寻周期和次数都将减少 ,决策的速度从而可以加快。网上信息搜寻沿着特定的路径进行 ,搜寻成本已不再是信息搜寻中最主要的影响因素 ,市场的成熟情况、网络的传输率等将成为搜寻原则中新的内容
This paper studies the price discretization of online commodities in an empirical way, and proves that because of the balanced distribution of information in the market, the transparency of costs and prices is improved and the prices of online commodities tend to converge. In the complete information market, traders reduce the enthusiasm for information collection when the cost of information acquisition is very low or zero, and the searching period and frequency of information seekers will decrease and the speed of making decisions can be accelerated. Search information is no longer the most important factor in information search. The maturity of the market and the transmission rate of the Internet will become the new content in the search principle
