The social security base has declined. What happened?

The cost pressure of enterprises and the change of employees' total wage income.

1. Enterprise cost pressure: Social security expenses are an important expenditure of enterprises. In the face of short-term economic pressure or declining revenue, enterprises will reduce their burden by reducing the social security base.

2. Changes in total wage income of employees: The total wage income of employees increases, and the payment base of employees increases. The total wage income of employees decreases, and the base of employees' contributions decreases, so the base of social security decreases.
