Abstract: With the acceleration of population aging in China, the number of pure beneficiaries in the economy is higher than that of pure contributors, which seriously affects fiscal sustainability. This paper probes into the influence path and mechanism of population aging to fiscal sustainability in China, and numerically simulates the extent of such influence using a generational accounting method. Aging reduces the tax base and enlarges fiscal expenditure by reducing the quantity of labor and labor productivity, changing the resident’s consumption level and structure, cutting down the saving rate, and widening the gap between social security revenue and expenditure, all of which challenge the balance of the fiscal system. The empirical results show that the problem of inequality in terms of the fiscal burden across generations is extremely prominent and the per capita tax burden under different birth rate assumptions is obviously different. Under the pressure of aging, in order to maintain the fiscal balance, the future per capita tax burden will be increased by a maximum of 55.9%. Although increasing productivity and reducing interest rates can help reduce that gap, their roles are far less important than the role of fertility. In order to cope with aging, the fiscal system should see an increase in income, a reduction in expenditure, and a redeployment of structure. That is, while at the same time perfecting the tax system and widening the tax base, the expenditure structure should also be optimized.
