Is there a relationship between housing subsidies of government agencies and institutions and social security?

No. Housing subsidy is a subsidy given by the state to solve the housing problem of employees, that is, the funds originally used by the unit to build houses and purchase houses are converted into housing subsidies, which are not included in the scope of social security co-ordination, and belong to the payment items outside the overall planning, so the housing subsidies of government agencies and institutions have nothing to do with social security. Institutions refer to social service organizations organized by state organs or other organizations with the purpose of social welfare and engaged in education, science and technology, culture, health and other activities.
