Abstract:On the basis of the resource dependence theory and social network theory, constructed the theoretical model of the relationship between innovation cooperation network enterprise’s the value of knowledge, network position and network power. Based on the data collected from xi’an information technology industry, using multiple regression method for the relationship between enterprise’s the value of knowledge, network position and network power to empirical research. The results showed that the knowledge criticality and the knowledge nonsubstitutability positively correlated with network power, but the knowledge centrality was not correlated with network power; Enterprise’s network position positively moderated the relationship between the knowledge criticality and network power; Enterprise’s network position positively moderated the relationship between the knowledge nonsubstitutability and network power; But enterprise’s network position did not moderated the relationship between the knowledge centrality and network power.
