The influence of friendship and communication network density on individual innovative behaviours: a multilevel study

The present study examines whether teams’ friendship and communication network density are related to individual innovative behaviours (IIBs: idea generation, suggestion making, idea promotion and idea implementation).

The results obtained by means of multilevel structural equations modelling showed that friendship network density had an indirect positive relationship with the four IIBs through the density of team communication networks.
