Patent collaboration network was used to denote the industrial innovation network architecture. Collaborative patents related to automobile industry for 1985 to 2009 from State Intellectual Property Office of the P.R.C(SIPO) were employed to UCINET6 to draw topology maps. The co-integration equations were constructed to test their impacts on network performance. The results have shown that cliquish technology collaboration is an important path to push innovation networks' development. It has long-term, steady and positive influence on the performance of industrial technological innovation, and this effect is more significant on the low-novelty innovation.
