Research on Evolution of Risk Management Behavior of Participants in Technological Innovation for the Sichuan-Tibet Railway

To ensure the successful completion of the Sichuan-Tibet Railway technological innovation project, it is necessary to drive the participants to take active risk management measures in the process. An evolutionary game model was established based on three risk perception factors: management cost, risk loss, and loss compensation, and MATLAB numerical simulation was used to analyze the risk management behaviors of the coordinator, the demander, and the researcher. The results show that different levels of risk perception factors can affect the risk management behaviors of the three participants to different degrees, and when the parameter adjustment exceeds the threshold, the risk management behaviors of the three parties will be changed. Conclusion: Taking rational control of active risk management costs, setting up emergency reserves, increasing penalties on negative risk managers, and making coordinators bear more risk losses can promote the adoption of active risk management strategies by innovative participants.
