Abstract: Starting from the characteristics of spectrum resources, it is pointed out that the seriously scarce spectrum resources are one of the main bottlenecks of 5G development and application To solve this problem, the existing allocation of spectrum resources must be improved The original allocation system of spectrum resources in China has resulted in the coexistence of shortage and excess Only by establishing the dual dynamic adjustment mechanism of government and market, can the allocation process of spectrum resources be optimized through Pareto improvement

Key words:  spectrum resources, scarcity, dynamic adjustment mechanism
