Population Aging,Social Security Expenditure and Income Distribution
Promoting long-term balanced population development and solidly promoting shared prosperity are the strategic goals of China during the period of the 14th Five-Year Plan.This paper theoretically describes the relationship among population aging,shared pros-perity,social security expenditure and income distribution under the unified framework,and quantitatively evaluates the income distribu-tion effects of population aging and social security expenditure.The results show that population aging is a key driving factor of China's imbalance in income distribution,and the aggravation of population aging significantly expands income inequality.On the whole,such factors as uneven development and a relatively low level of expenditure limit the regulatory role of social security expenditure in income distribution,and its redistribution function needs further optimization.In addition,population aging and social security expenditure have an interactive effect on income distribution.With the increase of the social security expenditure,the marginal impact of aging on income distribution will gradually weaken.Based on the above discussion,it can be concluded that in order to gradually reverse the negative im-pact of population aging on the distribution pattern of the national income,it is necessary to moderately increase the social security ex-penditure on the basis of strengthening the principle of social security solidarity in order to better achieve social equity.
