Abstract:Based on the patent data from 2001 to 2018 in the field of nano-energy, knowledge networks and innovation cooperation networks between R D organizations are constructed. The relationship between the two dimensions of knowledge resources and R D organizations’ innovation performance and the moderating role of network knowledge heterogeneity are tested. It is found that R D organizations’ knowledge combinatorial capability has a positive impact on innovation performance, and there is an inverted U-shaped relationship between R D organization"s knowledge diversity and innovation performance. Knowledge heterogeneity in innovation networks negatively regulates the impact of knowledge combinatorial capability on innovation performance, and positively regulates the inverted U-shaped relationship between knowledge diversity and innovation performance.
