The level of basic public services that mobile elderly population can enjoy depends on the degree of openness of the local government to them.Based on the residence permit system and its related elderly preferential policies,a basic pub-lic service supply openness index system and measurement model for the mobile elderly population are constructed.Taking Nan-jing City as the sample area,the openness of basic public serv-ice supply for the mobile elderly population is measured.The re-sults show that the supply of basic public services in the local ar-ea is not fully open to the floating elderly population,and the o-verall openness is not high,and there is still a distance from service equalization;There are significant differences in the openness of basic public service supply among different catego-ries.For example,the openness of basic cultural and sports service supply is 1,which belongs to complete openness,while the openness of basic elderly care service supply is only 0.246,which is extremely low and not friendly to the residence of mo-bile elderly population in cities;The utilization rate of various basic public services by the floating elderly population is rela-tively low,which is not only limited by external institutional pol-icies,but also by subjective cognitive limitations.Local govern-ments should expand the scope of service openness and reduce service constraints in a targeted manner based on the characteris-tics and needs of the mobile elderly population.They should pay attention to and gradually open up basic public service projects with exclusive characteristics,and focus on strengthening service promotion and improving service awareness to ensure the service security of the mobile elderly population.
