Social Security Expenditure and Common Prosperity——Threshold Effect of Local Fiscal Revenue
Based on the panel data of 30 provinces in China from 1998 to 2022,this paper uses the fixed effect model and long difference model to analyze the effect of social security expenditure on common prosperity and its channel.The results show that social security expenditure significantly promotes common prosperity,and moreover,social security expenditure is also a long-term mechanism to achieve common prosperity effect.The results of channel test confirm that the horizontal transfer payment of social security within the province is the channel of financial social security expenditure affecting common prosperity.The results of threshold test show that the promoting effect of social security expenditure on common prosperity increases first and then decreases with the growth of local fiscal revenue.Therefore,we should continue to optimize the structure of social security expenditure,strengthen the mechanism of intra-provincial horizontal transfer payment,make efforts to raise the level of social security coordination,and explore to establish the mechanism of inter-provincial horizontal transfer payment for social security.
