How is the contribution ratio of all kinds of social security stipulated?

Legal analysis: the proportion of social security contributions consists of individual contributions and unit contributions. Social security contributions vary from region to region, and the base is based on the total wages. Because the payment base and compensation base of the five major social insurance types, such as pension, work injury, medical care, maternity and unemployment, are linked to the average salary of employees on the job last year, the increase of the average salary level will bring about the adjustment of various social insurance types.

Legal basis:
