| As innovation becomes increasingly important in a competitive market environment,many organizations use social media technologies such as We Chat and QQ not only as tools for employees’ daily work communication and collaboration,but also as platforms and resources to support employee innovation.In this context,the relationship between employee social media use and innovation has gradually attracted the attention of management scholars and practitioners.However,most existing studies have focused on the impact of employee social media use on innovation at the individual level,and few have addressed social media use at the higher level,such as teams.In fact,due to frequent team collaboration and interaction,collective social media use,in which team members rely on and influence each other,is becoming more and more common and may have different impacts,so it is necessary to distinguish it from individual-level employee social media use and explore it separately.In addition,existing research findings on the impact of social media use on innovation have not been unanimous,with both facilitative and hindering perspectives coexisting,and it is necessary to explore the key boundary conditions that may reconcile these conflicting findings.Based on this,this study uses the Enabler-Process-Outcome Framework as the basis for constructing a cross-layer model of team members’ social media use influencing members’ innovative behaviors by combining member trust and team task interdependence.The study used a cross-level model of team members’ social media use to influence members’ innovative behavior.The study used a questionnaire to collect data.SPSS22.0 and MPLUS7.4 software were used to empirically test the model on 350 team members’ questionnaire data from 52 work teams,and the following findings were drawn: First,team members’ task-oriented social media use positively influences members’ innovative behavior through the partial mediating role of cognitive trust.Second,team members’ relationship-oriented social media use positively influenced members’ innovative behavior through the partial mediating role of affective trust.Third,team task interdependence positively moderates the relationship between team members’ task-oriented social media use and cognitive trust,and further moderates the indirect effect of team members’ task-oriented social media use via cognitive trust on members’ innovative behavior.Fourth,team task interdependence positively moderates the relationship between team members’ relationship-oriented social media use and affective trust,and further moderates the indirect effect of team members’ relationship-oriented social media use on members’ innovative behavior via affective trust.In summary,this study examines the cross-level mediating effects of team members’ task-oriented and relationship-oriented social media use on members’ innovative behaviors through cognitive trust and emotional trust and the crosslevel moderating effects of team task interdependence.This study expands the research level of employee social media use,reveals the intrinsic mechanism of team members’ social media use influencing members’ innovative behaviors through trust and the moderating mechanism of team task interdependence,refines the intrinsic mechanism of team members’ social media use,and provides useful guidance for the management practice of team-level social media use. |
