In this study, we explore what can affect the development of team cohesion in the entrepreneurial team. We show the relationship between team members' cohesion and team performance over five main categories: (Ⅰ) Prior Condition, (Ⅱ) Conflict, (Ⅲ) Strategy, (Ⅳ) Task Interaction in the team, (Ⅴ) Social interaction in the team. Based on the research method of comparative cases, we selected six Chinese entrepreneurial teams as research objects. We show how individual behaviour affects the development of team cohesion in the entrepreneurial team at the individual level and team level. More specifically, we consider that entrepreneurial team cohesion changes are more complicated than traditional teams. The team cohesion of the entrepreneurial team has certain randomness because there is no guidance from the leader. The influence of personal factors on team cohesion will be more intense. When the entrepreneurial team improves team cohesion, team members need to participate more.
