Provincial social security is suitable for residents in the whole province, which can ensure that the insured enjoy relatively consistent social security rights and interests in different regions and reduce the complexity of administrative management.

Municipal social security has high medical security, centralized medical resources, accurate use of medical insurance funds, and easier access to more advanced medical services. The social security of municipal organs is relatively high, and the urban population is relatively concentrated. The social security of municipal organs may face greater pressure for providing for the elderly.
