Based on the concept of team integration and collaboration, team fault lines has considered the multiple characteristics of team members and enriched the research of team attributes. Since its concept was proposed in 1998, it has attracted the attention of many researchers.This paper focused on the relationship between team faultlines and innovation, selected CNKI and Web of Science, and used Citespace Ⅲ software to do the information mining of knowledge measurement.The article further summarized the literature, and found that the relationship between team faultlines and innovation has broken through the simple impact study. Researchers have explored the mechanism of action between the two aspects from different aspects.The team faultlines has been decomposed into different types to develop more strength calculation methods, and the article summarized their different impact on innovation.With regard to the newly proposed method of calculating the width of the faultlines, the research on its relationship with innovation has not received sufficient attention.By constructing a research framework model of the relationship between team faultlines and innovation, the author summarized the context of existing research, and then pointed out the shortcomings of existing research and future research directions.
