Abstract Based on data of patents application about enterprise-university-institute collaboration associated with A-share listed companies from 1998 to 2019, dynamic patents collaboration networks are constructed.Using complex network analysis methods, we analyze the evolution trends of the whole structure of E-U-I patent collaboration, and explore dynamic patterns of collaboration intensity,knowledge absorptive capacity, knowledge control capacity, and cluster development capacity from three kinds of perspectives which are factor intensity, life cycle, and regional location. The results show that,regardless of enterprise characteristics,the collaborations among enterprises, universities, and institutes become more widespread, density gradually decreases, the small-world properties get greater, the scale-free structure becomes gradually stable and innovation clusters are more and more independent. Gaps in knowledge capacity or knowledge control capacity between enterprises get narrower, but those in cluster development capacity become wider. Compared with factor intensity, life cycle and regional location have a greater impact on the structure of the E-U-I collaboration network. These findings provide empirical support for government decisions to stimulate enterprise innovation vitality and promote the coordinated development of regional innovation.
