For the purpose we collected data from 267 online gamers via a web-based questionnaire survey in China. With the help of researches up to the present, we proposed a research model which consist of four latent variables such as E-service quality, product factor, perceived value and customer satisfaction. Through structural equation model analysis, we found that: first, E-service quality and product factor have positive effect on the customer perceived value, and E-service quality has a greater impact on customer satisfaction; second, E-service quality has a significant effect on perceived value, and it is notable that the effect is bigger for the high-involvement group than low-involvement group; third, perceived value not only direct affect customer satisfaction, but also plays an important intermediary role in the formation of customer satisfaction.
