Together with the growth of the sharing economy, online transaction trust has become a major obstacle to the development of this economic model. This paper sorts out the theories of consumer trust by domestic and foreign scholars in Vietnam and the research results of the sharing economy development model. Based on the actual situation of the sharing economy development in Vietnam, the influencing factors are summarized into three aspects: individual consumer factors, sharing platform factors and social factors. At the same time, we look forward to the research and propose future research directions, hoping to provide a reference for Vietnam's sharing of economic trust.
