Partners' centrality diversity and firm innovation performance: Evidence from China

While most studies of firm innovation with a social network perspective have focused on the focal firm's network structure, we explore the value of second-order social capital by examining partners' network structure to better understand firm innovation. Specifically, we examine how centrality diversity of the focal firm's network partners affects its innovation performance. A longitudinal study of Chinese publicly listed manufacturing firms from 2000 to 2016 indicates that partners' centrality diversity in a firm's board interlock network is positively related to that firm's innovation performance. We also find that the focal firm's knowledge breadth weakens the effect of partners' centrality diversity on innovation performance for the focal firm, while the proportion of non-independent ties between the focal firm and its network partners strengthens the effect.
