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.
