Abstract: Abstract：Open Knowledge Exchange is the core factor for maintaining and cooperating Technology Innovation Network (TIN), its path construction and executive strategy directly effect on innovative resource arrangement and integration. It elaborates the Knowledge Exchange Path characteristics from external environment, participant behavior, composed elements and exchange rules, and puts forward three path structure types including of group positions and usage scopes, such as complementary-bilateral mode, modular-multilateral mode and cross platform-hybrid mode, all these are for the Open Knowledge Path recognition methods. It uses Kalman-Filter to estimate the whole process of Open Knowledge Exchange including of the statement transformation condition, identification methods and operation rules. Finally, it verifies that the network effects from path recognition model which are consistent with TIN actual operation and the management policies are formed for open knowledge network. The empirical results show that the path efficiency and quality would activate knowledge innovation and improve beneficial economic cycle for TIN ecosystem.

Key words:  knowledge exchange behavior, path recognition method, network effect, technology innovation network (TIN)
