Abstract: In order to reveal the mechanism of innovation catalyst in technology innovation network, based on the theory of value co-creation, this paper analyzes the influence of technological innovation network routines replication on the catalyst of innovation, and further examines the mediating effect of inter-organizational dependence and the moderating effect of external search. With the data of high-tech enterprises in China, this paper makes an empirical test. The results show that, the micro dynamics of routines replication among technological innovation network organizations is the supporting condition for innovation catalyst based on the perspective of ambidexterity capabilities; the deconstruction dimensions of conventional routines replication and flexible routines replication have a positive impact on the catalyst of innovation. Inter-organizational dependence plays a different mediating role between routines replication and the catalyst of innovation, joint dependence plays a complete mediating role between convention routines replication and innovation catalyst, and asymmetric dependence plays a partial mediating role between flexible routines replication and innovation catalyst. External search positively moderates the effect between joint dependence and innovation catalyst, but the effect between asymmetric dependence and innovation catalyst is not significant. The external search positively moderates the mediating effect of joint dependence between convention routines replication and innovation catalyst, but it doesn't have any effect on the mediating role of asymmetric dependence. The conclusions extend the theory of innovation catalyst, help reveal the value of co-creation behavior for network organizations and contribute to the construction of innovation ecosystem.
