In the management structure of the endowment insurance fund, it is necessary to ensure the separation of income and expenditure and earmarking. At the same time, it is necessary to establish a supervision system at or above the provincial level to achieve unified management. As for the basic old-age insurance, the government should set up an independent special regulatory body. Enterprises and other insurance should also be supervised by institutions directly under the government, and a unified and centralized supervision mode should be implemented.

(B) the establishment of old-age security system for migrant workers

The development level of social productive forces, the administrative ability of the government and the development of the labor market determine which groups should be covered by this kind of social insurance. However, with the development of China's economy, China's old-age insurance will gradually cover all fields related to industrialization and marketization. However, migrant workers have always been a powerful group neglected in this process. Therefore, it is necessary to establish an old-age insurance system covering migrant workers immediately. In this way, it can not only alleviate the crisis of rural aging, but also improve the source of funds for old-age care. Only by bringing migrant workers into the old-age insurance system can we better fulfill our filial piety and improve parents' old-age welfare.

(C) with the help of the structural characteristics of the old-age insurance system to adjust the preservation and appreciation.

Only by constructing a new model framework of the endowment insurance fund can we really solve the problem of maintaining and increasing the value of the pension, that is, enterprises and individuals have the right to choose investment capital market or insurance market under the investment operation mode of the fund while the government enforces the personal account savings plan, so as to solve the problem theoretically. Of course, to truly maintain and increase the value of the fund, it is necessary to further improve the financial market and investment system.

(4) Enterprises delay the retirement age in stages, and institutions reduce the wage replacement rate.

Compared with developed industrialized countries, the retirement age in China is generally lower (most men in the world are 65 years old and women are 60 years old). At present, there are 60 males and 55 females (workers are 50 years old) in China, and the wage replacement rate has been very high. With the continuous improvement of living standards and the progress of medical technology in China, people's life expectancy is generally extended, which makes China under great pressure in the aspect of old-age insurance. If some enterprises adopt flexible retirement age, it can improve social productivity and promote economic growth. At present, some institutions implement the replacement rate of 100%. I personally suggest reducing the wage replacement rate of these institutions.
