Abstract: The formation mechanism of emerging technology "multi-core" innovation network is analyzed, and the knowledge growth mechanism of emerging technology innovation network is studied, a dual bidirectional formation model of emerging technology "multi-core" innovation network is constructed.The simulation method is used to dynamically simulate the forming process of emerging technology "multi-core" innovation network, and to analyze the network structure and dynamic evolution rule of the emerging technology innovation network. The research shows that the formation of emerging technology innovation networks with life cycle characteristics depends on inter firm knowledge transfer behavior; During the formation and development of the network, the state of knowledge grows most rapidly and tends to be saturated; The network in the stability period has scale-free characteristics and presents a multi-core network structure; By increasing the frequency and scope of knowledge transfer, emerging technology enterprises accelerate the upgrading of enterprise knowledge status, which is an effective way to become the core enterprises of the network.
