Abstract:On the basis of analyzing the background and significance of enterprise knowledge collaboration in innovation network, this paper combines the theoretical basis of knowledge collaboration and knowledge collaboration effectiveness, starting from the meaning of "efficiency", the effectiveness is divided into two dimensions: knowledge collaboration performance and knowledge collaboration ability, and the evaluation index system of enterprise knowledge collaboration effectiveness in innovation network is constructed, which includes two first-level indexes, five second-level indicators and 25 third-level indicators. Then, the evaluation model is established by using factor analysis method, and the effectiveness of enterprise knowledge collaboration in innovation network is reflected on each factor. Finally, through the empirical analysis, the validity, rationality and scientific nature of the evaluation model are tested, which provides a theoretical basis and decision reference for the evaluation of the effectiveness of enterprise knowledge collaboration in the innovation network.
