中文摘要：

利用我国738家企业1985～2011年间在汽车产业申请的专利数据,探讨了企业知识网络中心势对其二元式创新绩效的影响,并分析知识多元化对企业知识网络中心势与二元式创新绩效关系的调节效应.研究表明,企业知识网络中心势与利用式创新绩效呈正向关系,企业知识网络中心势与探索式创新绩效呈负向关系;知识多元化对利用式和探索式创新绩效均具有促进作用;知识多元化减弱了知识网络中心势与探索式创新绩效的负向关系,但知识多元化对知识网络中心势与利用式创新绩效正向关系的调节效应不显著.

英文摘要：

In this study, we use patent data of China automobile industry from 1995 to 2011 in 738 firms. We discuss the impact of knowledge network centralization on firms＇ exploitative and exploratory innovation performance. We also analyze the moderating effect of knowledge variety on the relationship of knowledge network centralization and innovation performance. The empirical results show that knowledge network centralization has a positive relationship with a firm＇s exploitative innovation performance, and has a negative relationship with a firm＇s exploratory innovation performance. Knowledge variety also positively affects firms＇ exploitative and exploratory innovation performance. At the same time, knowledge variety weakens the negative relationship between knowledge network centralization and exploratory innovation performance, but the moderating effect of knowledge variety on the positive relationship between knowledge network centralization and exploitative innovation performance is not significant.
