The establishment of the national social security fund is an important strategic decision made by the CPC Central Committee and the State Council. This decision is of far-reaching significance for safeguarding the long-term interests of the national people's social security and promoting the establishment of a harmonious society. First, it is conducive to improving China's social security system. Social insurance funds mainly come from individuals, enterprises and local governments. The establishment of a huge national social security reserve fund by the central government is conducive to maintaining and improving the level of social security. Second, the expansion and preservation of the national social security fund is conducive to solving the income and expenditure gap of China's aging population pension. Third, the national social security fund raised every year is not used for the expenditure of that year, but for accumulation. This huge sum of money is used for various investments, which needs to preserve and increase value, and is also conducive to promoting the development of China's financial market and the adjustment of economic structure. This strategic decision made by the CPC Central Committee and the State Council has been welcomed by people all over the country and widely praised by countries and people around the world.
