With the increasingly fierce market competition and the increasing difficult problem and scale of construction projects, the problem of project conflicts has become increasingly serious, with team conflicts being the most prominent. In the process of construction projects, there are usually functional conflict and destructive conflict.Different kinds of conflicts can interact and transform, they have a positive or negative effect on project performance. Therefore, the handling of conflicts is crucial. As a key factor in resolving conflicts, the action of organizational climate in team conflicts and project performance deserves further exploration. Therefore, this article studies the relationship among organizational climate, team conflict, and project performance in construction projects, with the aim of providing theoretical guidance and decision reference for conflict managers. By analyzing and summarizing relevant literature, this article starts from the inherent characteristics of construction projects and project-based organizational characteristics and divides organizational climate into three dimensions: fairness perception, contract flexibility, and Organizational incentives. Divide conflicts into three dimensions: task conflicts, process conflicts, and relationship conflicts. Then analyze the relationship among the dimensions of organizational climate, different kinds of conflicts, and project performance. The research results indicate that: Organizational incentives, perceived fairness, and task conflict are significantly positively correlated, while process conflict and relationship conflict are significantly negatively correlated.Contract flexibility is significantly negatively correlated with process and relationship conflicts, and positively correlated with task conflicts. Task conflict is significantly positively correlated with project performance, while relationship conflict and process conflict are significantly negatively correlated with project performance.Organizational incentives, perceived fairness, and contract flexibility are significantly positively correlated with project performance. Conflict plays a partial mediating role in the impact of organizational climate on project performance. There is a significant negative correlation between team conflict and project performance, a significant negative correlation between team conflict and organizational climate, and a significant positive correlation between organizational climate and project performance.
