Why does Shanghai's social security base increase year by year?

The base of social security contributions keeps rising with the change of social wages, which ultimately affects the annual growth of social security contributions paid by ourselves.

Social insurance fee = payment base × payment ratio.

As long as the average social wage rises, the minimum social security premium will also rise.

In fact, the increase in social security costs is a good trend for the country and the people, because it reflects that the living standards and economic levels of ordinary people have improved to varying degrees.
