This study aimed to identify strategy characteristics for sustainable competitive advantage in businesses utilizing the sharing economy (SE) and to investigate whether such strategy characteristics are related to creating shared value (CSV) and performance. A total of 631 participants who had used goods and services of SE businesses were selected as the unit of analysis in reference to the components of business-to-peer (B2P) and peer-to-peer (P2P) SE business models. Reliability, validity, and goodness-of-fit tests and path analysis were performed using SPSS and AMOS statistical packages. The following results were obtained. First, regarding the relationship between strategy characteristics for sustainable competitive advantage and “social congruence,” which is related to creating shared value, this variable was significantly influenced by “value network” in the B2P model and “strategic innovation” and “strategic resources” in the P2P model. Second, regarding relationship with the aforementioned strategy characteristics and “value of information sharing,” the latter variable was significantly influenced by “moment of truth,” “strategic innovation,” and “value network” in the B2P model, and “moment of truth,” “strategic resources,” and “value network” in the P2P model. Third, regarding the relationship among variables related to CSV and their contribution to performance, “social value congruence” was affected by “value of information sharing,” and these variables had significant effects on “value of participation” in both models. Only “value of participation” made a significant contribution to “performance.”
