Legal analysis: When the economic development is declining, the unemployment rate is rising and people's living standards are declining, the national social security fund can supplement people, thus stimulating demand and improving social demand. On the contrary, when the economic development speeds up and the unemployment rate drops, the social security expenditure will be reduced accordingly, so that the immediate total social demand will not be excessively inflated. Therefore, the national social security fund can play a role in promoting and stabilizing economic development.

Legal basis: Article 64 of People's Republic of China (PRC) Social Insurance Law includes basic endowment insurance fund, basic medical insurance fund, industrial injury insurance fund, unemployment insurance fund and maternity insurance fund. In addition to the basic medical insurance fund and maternity insurance fund combined accounting, other social insurance funds are accounted for separately according to social insurance types. Social insurance funds implement a unified accounting system throughout the country. The social insurance fund is earmarked for special purposes, and no organization or individual may occupy or misappropriate it. The basic old-age insurance fund will gradually implement national overall planning, and other social insurance funds will gradually implement provincial overall planning. The specific time and steps shall be stipulated by the State Council.
