The purpose of this research is to discover the structural factors of technology readiness indices of O2O service users and O2O service’s characteristics from previous researches, and then explore whether technology readiness indices(optimism, innovativeness) and O2O service’s characteristics(funny) have an impact on consumer satisfaction, and consumer satisfaction on consumer loyalty focusing on the Chinese market. This research has a significant impact on successful maintenance and management of an O2O service enterprise. Accordingly, a variety of practical and viable operational strategies are proposed. Data were collected from Chinese consumers who purchased products through O2O service. The research has gone through a basic statistical analysis primarily. Hypothesises were set and tested using statistical analysis of the questionnaire data. The reliability was tested using Cronbach’s alpha coefficient. In addition, the validity was analysed using Factor Analysis. What is more, the 5 variables were analysed using regression analysis in our research, and our research hypotheses were verified. The analysis results are summarized as follows. This research finds that among the technology readiness indices’ optimism, innovativeness have positive effect on consumer satisfaction. But the O2O service’s characteristics(funny) have not significant effect on consumer satisfaction. As the results demonstrated, the consumer satisfaction increases along with technology readiness indices’ optimism, innovativeness. What is more, the findings also illustrate that the degree of impact on consumer satisfaction decreases one after another in the order of technology readiness indices’ optimism, innovativeness. And consumer satisfaction have positive impact on consumer loyalty.
