Abstract: For the research on the co-creation value distribution of enterprise innovation networks, scholars mostly use cooperative game methods, using Shapley values and modified Shapley values for distribution, ignoring the impact of network connection structure, the direction and strength of the connection relationship on the distribution of co-creation value. In this paper, the edge density is used to characterize the connection structure in the innovative network, and the Myerson value considering the network connection structure is constructed, and it is proved that it is the only distribution law that satisfies the validity and fairness of the branch. Secondly, the direction and strength of the connection relationship are measured by the importance of the enterprise in the innovation network, and the Myerson value considering the network connection structure is corrected, and the cooperative game solution of the co-creation value distribution of the enterprise innovation network is obtained. Finally, through the numerical test and comparative analysis, it is revealed that the cooperative game solution constructed in this paper is not only reasonable and effective in solving the problem of co-creation value distribution of innovation networks, but also provides a more general allocation method with wide application value.
