Abstract: Based on the differences in the degree of collaboration between subjects,two types of business models of knowledge-oriented collaboration and transaction-oriented collaboration were divided,and a tripartite evolutionary game model of manufacturing enterprises,digital service platforms and end consumers was constructed.The perturbation process,containment behavior and equilibrium state of the driving force and retarding force factors on the stability of the synergistic system under digital empowerment were described.The simulation showed that the value convergence of the tripartite collaborative innovation was promoted by the endogenous power and exogenous power;the relational blocking factor had a two-way adjustment effect,and the embedded blocking factor had a threshold,which reversely regulated the cooperative behavior of the tripartite collaborative innovation.The digital service platform's perception of multi-factor changes was significantly higher than that of manufacturing enterprises and end consumers.In the process of two-way collaboration between manufacturing enterprises and digital service platforms,end consumers were more inclined to establish strong dependencies.The deep collaboration of multiple entities provided behavioral guidance and theoretical support for the value mining of tacit knowledge and the formation of high-end value networks.
