Legal analysis: China's old-age insurance system starts from county-level co-ordination, and by the end of 2020, it will eventually realize provincial unified revenue and expenditure, thus solving the problem of unbalanced burden of old-age insurance funds in the province. In 20021year, the income of the basic old-age insurance fund for enterprise employees was about 4.4 trillion yuan, and the fund expenditure was about 4. 1 trillion yuan, and the fund operation was generally stable. However, due to the uneven development of different regions in China, the differences in the level of economic development and the age structure of the population, the structural contradictions of pension funds among provinces are increasingly prominent. Some provinces have large fund balances, but in some provinces with relatively heavy aging population, the expenditure pressure of endowment insurance funds is greater. 20 18-202 1 implements the central fund transfer system, and rich provinces transfer funds to difficult provinces across provinces to "ensure the timely and full payment of pensions". In the past four years, * * * inter-provincial transfer payments amounted to more than 600 billion yuan, of which 202 1 inter-provincial transfer payments reached more than 2 10 billion yuan, which strongly supported the difficult provinces to ensure that pensions were paid in full and on time. This is the forerunner of national overall planning.
