The Relationships among Characteristics of Interlocking Directorate Network, Technological Diversity and Innovation Performance: Evidence from Taiwan’s Electronics Industry 176 On the other hand, prior studies find that high network density is not conducive to innovation performance and corporate performance (e.g., Kim, 2005; Yu and Chang, 2014). Our analyses again prove these findings. 5.2.2 Our analyses show that directors’ network sizes, network structural holes, and network centrality have significant and positive impacts on innovation performance via technological diversity. Therefore, this study suggests that companies expand their directors’ social networks, and encourage these directors to take on bridging or central roles in such networks so as to absorb and transmit important information. In doing so, companies can develop their strategies of technology diversification, enhance their innovation capability, and strengthen their competitiveness. 5.2.3 Our analyses also suggest that companies benefit from hiring board members from other industries, or board members expanding their external connections to experts from dissimilar industries or business groups. All these networks will help companies acquire various knowledge and key technologies, enhance corporate technological diversity, and gain competitive advantages in innovation.
