This paper explores the concept of knowledge networks in order to disclose how firms are able to increase innovative performance as a result of network structure and network content, which concern how firms connect with network partners (network structure), what the essence of exchange is for firms to acquire knowledge in the network (knowledge heterogeneity), and why firms need to cooperate with others (knowledge cognition). By using a sample of 144 high-technology firms in Taiwan’s science parks to test the hypotheses, the results of this study show that, while network structures do impact on a firm’s innovative performance, access to heterogeneous knowledge and increasing a firm’s knowledge in terms of defining and recognizing novel knowledge should be considered, since both play critical roles in facilitating innovative performance. These findings suggest that knowledge flow through a firm’s relationships must be understood in terms of network structure and content.
