Abstract: Enterprise knowledge team is the main carrier of knowledge innovation. The production of two types of enterprise knowledge team is explored: the type of single blood and the type of multi-blood. It also builds the production model to help analyses. On the basis of these two different types, it further demonstrates the mechanism of these two different enterprise knowledge teams and constructs the knowledge innovation model. The knowledge innovation mechanism is made up from feedback mechanism, remedy mechanism, catalytic mechanism, safeguard mechanism, coordinational evolution mechanism, and management mechanism.
