Abstract:Based on the Big Five personality theory and the technology acceptance model as a theoretical framework, a suitable online reputation system satisfaction scale was designed, and the relationship between personality traits, consumer perception and online reputation system satisfaction was explored. The results show that the higher the neuroticism, the more critical the use of the online reputation system, and the lower the perceived usefulness and perceived ease of use. People with higher openness, friendliness and a sense of responsibility have better perceived usefulness and perceived ease of use when using online reputation systems. Extraversion has no significant effect on the performance of perceived usefulness and perceived ease of use when using online reputation system. Both perceived ease of use and perceived usefulness have a positive impact on users’ satisfaction with the online reputation system.
