The Impact Mechanism Of Team Member's Advice Network Centrality On Knowledge Sharing Behavior

Facing the rapidly changing external environment,more and more modern organizations use the team as a working model to solve problems which are too complex for individuals to cope with.The knowledge sharing among team members can bring more awareness and problem-solving methods to the team and improve team performance.But the reality is that team members are not willing to share knowledge,and knowledge hiding behavior is widespread.Therefore,the team knowledge sharing becomes the common concern of both academic and management fields.The team advice network is formed from the daily information interactions between team members,and the network centrality measures the extent of members close to the center.Though existing researches have demonstrated that the team member's advice network centrality had a positive effect on his/her knowledge sharing behavior,its mechanism needs further study.Therefore,in order to better understand the effect of advice network centrality on knowledge sharing behavior,this paper is aim to explore the influence path and boundary conditions.Firstly,this paper makes clear of the relationship among anvice network centrality,knowledge self-efficay,organizational reward,anticipated reciprocity and knowledge sharing behavior based on literature review and proposed our hypotheses ypothesis.Secondly,by the use of SPSS and AMOS,this paper anylizes the data from 413 emplyees of 45 teams to test the hypotheses.And at last,this paper offers suggestion of knowledge sharing management.Main conclusions of this study are as follows:(1)Team member's advice network centrality has a positive effect on the knowledge sharing behavior.As resources delivered in Intra-team advice network,the member occupied the central position of the network own s rich resources and influence,and thus has more opportunities and higher capacity of knowledge sharing;(2)Team member's advice network centrality has a positive effect on knowledge self-efficacy.The member occupied the central position of the network has more information exchange activities to accumulate knowledge and experience as well as the appreciation from workmates which contributes to the promotion of knowledge self-efficacy;(3)Knowledge self-efficacy is a partial mediator between advice network centrality and knowledge sharing behavior.That is,advice network centrality can both directly facilitate the knowledge sharing behavior and indirect influence it via knowledge self-efficacy;(4)organizational reward has a “crowding-out” effect on knowledge self-efficacy.That is,with the raise of organizational reward,the effect of knowledge self-efficacy on knowledge sharing behavior is weakened,and the mediating effect as well;(5)Anticipated reciprocity has a “crowding-in” effect on knowledge self-efficacy.That is,with the raise of anticipated reciprocity,the effect of knowledge self-efficacy on knowledge sharing behavior is strengthened,and the mediating effect as well.
