Fuzzy Comprehensive Evaluation of Traveling E-commerce Based 0n Value Creation——Empirical Research On CTRP and ELONG [PDF]
, 2009 旅游电子商务评价研究是在特定的理论基础上构建评价指标体系，通过选取合理的评价方法进行定量分析，从而发现旅游电子商务的关键影响因素，并计算被评价旅游电子商务模式的得分从而评价其优劣。国内对旅游电子商务评价的研究还处于起步阶段，主要是网站功能的评价，评价方法也缺乏规范。本文引入了模糊综合评价方法用于旅游电子商务的评价研究。因为目前旅游电子商务的概念还不能得到科学和全面的界定，其主要影响因素的确定更是有待今后的探讨，所以对旅游电子商务的评价无法做到精确计算，模糊综合评价方法通过对精确性的逼近可以解决这一矛盾。
