As consumers participate in sharing their experiences, they become a powerful information source in online shopping malls. Previous studies have investigated information service in the company-created information perspective and trust in the company perspective. This study extends the perspective of company-consumers to consumers-consumer perspective in information satisfaction and trust. Also, this study suggests loyalty as voluntary behaviors and adds helping behavior to the loyalty. Our results show that information satisfactions influence trust in the information sources such as company and consumers. Moreover, trust in company and trust in consumers influence loyalty differently. While trust in company influences recommending stronger than trust in consumers, trust in consumers influence helping and repurchasing stronger than trust in company.
