It can be found from the previous studies that the individual-level neurotic personality in dark-traid personality is independent of work performance, but this individual-level influence may underrate the wide-ranging influence of neurotic personality on organizational performance. For the sake of the assessment of this possibility, this paper probes into how the team-level composition of neurotic personality impacts team cooperation as ell as performance with the big five model. The model data of this paper is collected from the performance statistics of the China Football Association Super League, while the data of neurotic personality is acquired from the players' Weibo, TikTok and TouTiao by web crawler.

The study proves that the team-level neurotic personality has an adverse impact on the team's work performance with obvious mediating effect of team cooperation, and the transformational leadership plays a positive regulatory role in the model.

This paper anticipates that the research conclusions can lay down the foundation for the study of dark-traid personality and the team construction of enterprise, and provide empirical support as well as reference for the follow-up detailed personality research..
