外部联系对研发人员探索式创新的影响——内部直接联系、外部合作网络多样性的调节效应

企业利用外部合作网络获取丰富的异质性资源，已成为促进探索式创新的重要途径，而研发人员作为企业创新活动主体，其合作网络的外部联系会影响个体探索式创新，进而影响企业整体探索式创新绩效。基于社会网络理论，在考虑内部直接联系和外部合作网络多样性调节效应的基础上，建立研发人员外部联系对探索式创新影响的概念模型，并提出研究假设。以我国电子信息制造业代表性企业华为公司与中兴公司为例，采用国家专利局授权的发明专利数据，利用负二项回归模型进行实证检验。研究结果表明：研发人员外部联系与其探索式创新呈显著倒U型关系；内部直接联系、外部合作网络成员多样性、外部合作网络知识多样性对二者的倒U型关系具有显著负向调节作用。

The Influence of External Connection on R&D Personnel′s Exploratory Innovation

It has become an important way for enterprises to obtain abundant heterogeneous resources by using external cooperative networks to promote exploratory innovation.As the main role of enterprise innovation activities,R&D personnel's external connection in the cooperation network will affect their individual exploratory innovation,which in turn will affect the overall exploratory innovation performance of the enterprise.Based on the theory of social network,considering the moderating effect of internal direct connection and diversity of external cooperative network,the conceptual model of the influence of external connection on R&D personnel’s exploratory innovation is established,and research hypotheses are proposed.The study is based on the patent data of Huawei & ZTE,the representative enterprise of China's electronic information manufacturing industry,which is authorized by the National Patent Office,and the hypotheses are tested empirically with negative binomial regression model.The results show that there is a significant inverted U-type relationship between R&D personnel's external connection and its exploratory innovation; The internal direct connection,the members diversity of the external cooperative network and the knowledge diversity of the external cooperative network have significant negative moderating effect on the inverted U-type relationship.
