Deposit base of housing provident fund: the deposit base of housing provident fund fluctuates: the minimum deposit base of housing provident fund shall not be lower than the minimum wage standard announced by the municipal government that year. The maximum deposit base is calculated according to the average monthly salary of employees in the previous year. Civil servants pay the provident fund in full according to the total wages, while private enterprises generally choose the lowest payment base within the floating base for cost reasons, which will lead to the civil servants' provident fund being higher than the employees' provident fund of private enterprises. Some private enterprises, in order to motivate their employees, prefer to give them high salaries, but choose a low base of provident fund, which will also make civil servants' provident fund higher than private enterprise employees.
