The research of psychological capital’ influencing factors are an important part and one of current theoretical hotspots of the psychological capital research. The influencing factors of the psychological capital are grouped into three categories: individual factors, leadership and intervention factors, and organizational and environmental factors. The existing researches on the influencing factors of the psychological capital not only have the problem of “total shortage”, but also require improvement in the research content, the research design and the research context. Based on the research status and the multi-dimension proposed framework, the follow-up study should pay more attention to the interaction effect among the influencing factors of the psychological capital and the excavation of mediation mechanisms and boundary conditions of the effect of the influencing factors. In the meanwhile, more cross-level and longitudinal research design should be employed and the context should be taken into account.
