The invention discloses a network twinning-based vehicle-road collaborative perception sharing method and system, and the method comprises the steps: proposing a road user intention correlation criterion in a dynamic scene, quantifying the traffic safety information value between road users according to the criterion, and enabling an infrastructure to selectively share the high-value road information with a vehicle; different sensing requirements of vehicles and real-time channel busy rates of infrastructures in a vehicle network are considered, a sensing information adaptive transmission frequency adjustment and dynamic bandwidth allocation algorithm under a multi-vehicle request scene is designed, and channel congestion and communication resource waste are avoided. According to the method, the optimization method is integrated, the time-varying characteristic of the infrastructure auxiliary vehicle system is considered, high-value safety information is shared and the transmission frequency of the infrastructure is dynamically adjusted according to the characteristics of low time delay, high flexibility and high reliability of network twinning, so that the collaborative awareness service quality is improved, the overall task completion time delay is reduced, and the system performance is improved. And the system information redundancy is reduced.
