Abstract: Research on the“black box”modeled by the effect of bonding and bridging social capital(SC) on ambidextrous innovation is still insufficient in the academia. The effect of bonding and bridging social capital on ambidextrous innovation in the knowledge-intensive enterprises is studied, and the mediating role of knowledge integration(KI) is explored.The results reveal that (1)both bonding and bridging social capital facilitate ambidextrous innovation positively, but not appearing inverted U-shaped relationship,while the effect of bonding social capital influencing exploitative innovation is more significant , the effect of bridging social capital influencing exploratory innovation is more significant; (2)the supplementary knowledge integration plays a mediating role in the relationship between bonding social capital and exploitative innovation as well as the relationship between bridging social capital and exploratory innovation. however, the complementary knowledge integration plays a mediating role only in the relationship between bridging social capital and exploratory innovation; (3)Cluster Analysis finds the enterprise with high level of bonding and bridging social capital promote ambidextrous innovation better.

摘要： 学术界对结合型与桥接型社会资本(SC)影响企业双元创新作用“黑箱”仍缺乏探讨。研究知识密集型企业结合型与桥接型SC对双元创新的影响，并探究知识整合(KI)的中介作用。结果表明：(1)结合型与桥接型SC均对利用性和探索性创新有促进作用，而未出现倒U型关系，但结合型SC更有利于利用性创新，桥接型SC对探索性创新的促进更强；(2)辅助性KI在结合型SC与利用性创新的关系中、在桥接型SC与利用性创新的关系中具有中介作用，而互补性KI仅在桥接型SC对探索性创新的影响中起中介作用；(3)聚类分析结果发现，当企业具有高水平结合型与桥接型SC时提升双元创新能力效果更佳。
