Abstract: Using the Chinese A-share listed companies from 2007 to 2015 as the sample and companies' independent directors as the research pbject, this paper applies the social network analysis method to examine the differences in the influence of the network center degree of the independent director's background on the innovation performance of the enterprise. It is found that the independent director network can improve the innovation performance of the enterprise, that is, the independent director's network center degree has a significant positive correlation with the innovation performance of the enterprise. After distinguishing the professional background of the independent director, it is found that when listed companies have independent directors with technical background, the relationship between the independent director's network center and the innovation performance is significantly enhanced, while in comapnies which do not have independent directors with technical background, the relationship is not significant. The conclusion of the research is that the independent director's network location is an important factor affecting the innovation performance of the enterprise. This influence is decided by whether the company has independent directors with technical background.

摘要： 本文以2007～2015年中国A股上市公司为样本,利用社会网络分析方法,考察不同专业背景独立董事的网络中心度对企业创新绩效影响的差异。研究发现:独立董事网络有助于企业创新绩效的提高,即独立董事网络中心度与企业创新绩效有显著的正相关关系;对独立董事的专业背景进行区分后,发现上市公司拥有技术背景独立董事时,公司独立董事网络中心度与创新绩效的正向关系显著增强。独立董事的网络位置是影响企业创新绩效的重要因素,这种影响随公司是否拥有技术背景独立董事而不同。
