摘　　要：为研究虚拟现实表征方式下,网上购物系统等级结构的宽度与深度特征对用户信息行为的影响,本文在实验室环境下研究了三种结构方式(8+6+1、16+3+1、4+4+3+1),结果初步发现:对于虚拟现实购物网站(或系统的虚拟现实表征方式),宽度的增加所带来的对用户信息搜索速度的损害大于深度的增加对用户信息搜索速度的损害,这与对二维表征方式下的既有研究结果相反;而且虚拟现实系统的8+6+1结构方式更容易带来用户的迷失。To find out the impact on users＇ information behavior of hierarchy depth and breadth in virtual reality representatives of E- Commerce-site, this article presents three hierarchy structures in the lab environment （8 ＋ 6 ＋ 1, 16 ＋ 3 ＋ 1,4 ＋ 4 ＋ 3 ＋ 1 ）. The preliminary results of this research are that the harmfulness of increased breadth in users＇ information searching speed is greater than that of increased depth in users＇ information searching speed, which runs counter to most existing studies in the two-dimensionality representative style; furthermore, users are likely lost in the structure model of 8 ＋ 6 ＋ 1 in virtual reality representatives.
