Therefore, the social security supplementary fund can be regarded as a social security plan of the government, which can help more people in need.

According to the policy, those who apply for subsidies must meet certain conditions, such as the income is not higher than a certain standard, and the social security contributions are due.

Therefore, the implementation of social security supplementary fund is of positive significance to the whole society, and it is a powerful tool to promote stable economic development and realize social equity.
