Public Cognitive Risk Transmission of Technological Innovation on Network with Community Structure

Considering that network community may have a great impact on public cognitive risk transmission of technological innovation, we introduce a network model with community structure, and its topological properties are analyzed. Next, a model of public cognitive risk transmission in technological innovation is constructed based on the network, and the model describes the transmission mechanism of public cognitive risk in the interactions. Final, we analyze how the strength of community structure, innovativeness and cognitive similarity, influence the transmission of public cognitive risk by simulations. Analysis results show that whether the public can form a consensus on the risk of technological innovation is highly correlated with the strength of community structure and cognitive similarity. Furthermore, the interaction between the public will amplify (or reduce) the public cognition risk of technological innovation under the impact of public innovativeness, when public innovativeness is high, the interaction will reduce the public's cognitive risk of technological innovation.
