Based on dual path model of commodity sales, an online reviews impact on the relationship between various factors, and then the theoretical hypothesis of each factor has been put forward in the model. As it is intuitive and strongly supported empirically, data including Chinese texts captured from Tmall.com was utilized, and then analyzed by SPSS and ROST CM6. Our empirical study on the reviews of Tmall.com indicated that the hypotheses are verified.展开更多

Theoretical research is first described, followed by the construction of eight self-established criteria of B2C portal quality measures and identification and compilation of requirements used by the I-Best, Opinia, E-bit and other institutes. After that, a portal quality evaluation is made by the web site content analysis;finally, a comparison of the rankings is presented. The obtained results showed that in spite of the lack of knowledge of the criteria adopted by INFO100 [1], there could be agreement with the criteria adopted in this study, because there was agreement with the results for the Ponto Frio portal. Therefore, it was concluded that the eight criteria used in this study can be useful in a quality analysis of B2C electronic portals.展开更多
