中文摘要：

以团队异质性、外部社会资本以及知识共享氛围作为团队层次变量，将创新绩效作为个体层次变量，考察了外部社会资本的跨层次中介以及知识共享氛围的调节作用。研究结果表明，关系取向异质性不会直接影响成员创新绩效，而任务相关异质性则会促进成员的创新绩效；外部社会资本在异质性与创新绩效之间起了中介作用；知识共享氛围在外部社会资本与成员创新绩效之间起到了跨层次的调节作用。此外，根据研究结果，提出了相关管理启示。

英文摘要：

To explore the effects of heterogeneity on team members innovation performance, the team-level effects of external social capital （capital structure, cognitive capital and relational capital）, cross-level effects and knowledge sharing willingness are taken as team level variables and the per- formance is taken as individual level variables. The results of the study show that： relationship orien- tation heterogeneity will not directly affect members of innovation performance; tasks related to heter- ogeneity have a positive effect on innovation performance of members; tasks orientation heterogeneity have a positive effect on team external social capital; external social capital plays a mediating role of cross level between team heterogeneity and innovation performance of team member; knowledge sha- ring intention plays a moderating role in the cross level between external social capital and innovation performance of the member. Finally, according to the conclusions above, some management implica- tions are provided.
