近年来，随着网络和信息技术的不断普及和提高，越来越多的消费者选择网络购物这种便捷的方式。但随之而来的一系列用户体验问题，不仅让消费者不满，同时也给企业带来了负面影响。在“用户体验”已经成为电子商务网站运营核心竞争力的今天，如何了解用户体验等级是非常重要的。本文站在消费者的角度，，以购物环节为主线，以ISO9126质量评价标准为原则，将二者有效的结合起来，组成关系矩阵，建立了一个相对全面立体的B2C电子商务网站用户体验评价体系。这里的B2C电子商务网站是针对于网络零售的。文中将购物环节分为了五个部分：浏览、选择、购买、物流和评价，又将每个环节展开为一些具体元素。这些元素与质量标准的四个特性（功能性、可用性、有效性、可靠性）相结合形成了评价指标体系。评价体系指标确立后，我们需要对每个指标进行评价。本文将用户体验分为５非常满意、４满意、３一般满意、２不满意、１非常不满意，这五个级别。根据一定的评价原则先得出每个评价环节的用户体验等级，然后再得出被评价企业的用户体验等级。希望该评价体系能够为消费者、企业和第三方评价机构提供有利的帮助，起到抛砖引玉的作用。
