With the popularity of virtual tools such as instant messaging and online office in organizations,
the use of technology in virtual spaces to organize interactions and accomplish specific tasks (i.e., virtual
collaboration) is becoming more and more common. How to better promote virtual collaboration has
aroused widespread concern in both business practice and theory. Based on social exchange theory
and social interdependence theory, the study collected a lot of primary data include 67 virtual teams of
high-tech enterprises, corresponding to include 293 team members, analyzed the effect of emotional
support of team members on virtual collaboration, and also the mediating effect of team trust and the
moderating effect of task interdependence. The results show that: (1) emotional support of team members
has a positive effect on virtual collaboration; (2) team trust (affect-based trust, cognition-based trust)
play a mediating role between emotional support of team members and virtual collaboration; (3) task
interdependence positively play a moderating role between team trust (affect-based trust, cognitionbased trust) and virtual collaboration. The above empirical results have important theoretical guiding
significance for promoting virtual collaboration, building team trust and setting team tasks.
