Structural Characteristics and Formation Mechanisms of Patent Collaboration Networks in China's Prefabricated Buildings

Inter-organizational collaborative innovation is crucial for advancing the development of prefabricated buildings (PBs). However, the structural characteristics and formation mechanisms of networks arising from such collaborative innovation remain unexplored. Using patent data on PBs in China (2010-2021), this study constructed patent collaboration networks (PCNs) and examined their structural characteristics using social network analysis and network motif analysis methods.
