The Influences of Team Network Structure and Relational Context on New Product Development Performance: The Mediation Effect of Shared Knowledge
Social factors in a networked group have been proposed as influential forces on collective knowledge and innovation activities. However, the interactive effects of variables from the distinctive dimensions these on knowledge and innovation management have yet been unclear. The present research, collecting and analyzing data on the group level-of-analysis, investigates the interactive effects of social structure and relational context on group knowledge sharing and new product development performance. Further, shared knowledge is discussed with dimensions of knowledge-sharing quality and quantity. Overall results suggest that network density and all interactive effects relating to this antecedent and relational context are positively and significantly influence knowledge sharing and NPD performance. The mediation effect of shared knowledge in the model is supported. Surprisingly, however, the network centralization was negative influence on shared knowledge supported; Moreover, the expected negative moderation of relational context does not show in our results. These surprising results, against our theoretical articulation, implies that further discussion on the traditionally perceived, if not common-sense, impacts of network centralization on knowledge activities need to be further re-investigated with careful theoretical elaboration.
