Abstract: This paper explored the main structure types and effect mechanism of the enterprise network search in the context of technological innovation network. First, by learning from the grounded theory and through 3 in-depth interviews, we found the main types of enterprise network search are knowledge search, relationships search and routine search. Meanwhile, we surveyed the cooperation networks of Xi'an High-tech enterprise as the object, and did an empirical test on the effect mechanism of network search. The results show that, moderate relationship search helps companies to achieve higher cooperation innovation performance, and that knowledge search not only improves cooperation innovation performance, but also has an intermediary role between relationship search and cooperation innovation performance, and that the positive relationship between routine search and cooperation innovation performance is passed through empirical testing, and that routine search also has a positively regulated relationship between knowledge search and cooperative innovation performance.

Key words: network search, knowledge search, relationship search, routine search, effect mechanism
