Legal analysis: there is no difference between social pooling and social insurance, and monthly pooling belongs to social insurance. Social pooling refers to the large-scale unified collection, management and use of social insurance funds by social insurance agencies within the territorial scope. This system adopts the traditional basic endowment insurance fund raising model.

Legal basis: Article 12 of the Social Insurance Law of People's Republic of China (PRC), the employer shall pay the basic old-age insurance premium according to the proportion of the total wages of its employees stipulated by the state and record it in the basic old-age insurance pooling fund. Employees shall pay the basic old-age insurance premium in accordance with the proportion of wages stipulated by the state and record it in their personal accounts. Individual industrial and commercial households without employees, part-time employees who have not participated in the basic old-age insurance in the employing unit and other flexible employees who have participated in the basic old-age insurance shall pay the basic old-age insurance premiums in accordance with state regulations and record them in the basic old-age insurance pooling fund and individual accounts respectively.
