Research On The Income Redistribution Effect Of Basic Endowment Insurance Expansion From The Perspective Of Common Prosperity

After building a moderately prosperous society in an all-round way as scheduled,China has embarked on a new journey to achieve the second centenary goal,and solidly promoting common prosperity is an important part of the second centenary goal.Basic endowment insurance has the characteristics of fairness and inclusiveness,and the strong income redistribution function helps to narrow the income gap of residents,and has become a key mechanism to promote common prosperity.In order to give full play to the function of social pension insurance income redistribution on a larger scale and in a wider field,the report of the 19 th National Congress of the Communist Party of China requires the implementation of the universal insurance plan,and the national "14th Five-Year Plan" outlines the goal of 95% participation rate in 2025.The expansion of basic endowment insurance is not only conducive to improving the social old-age security system shared by the whole people,fair and accessible,but also conducive to optimizing the pattern of income distribution and narrowing the gap between the rich and the poor.Based on this,this paper takes the employment groups outside the enterprise system such as flexible employees and migrant workers as the key objects of expansion,explores the income redistribution effect of the expansion of the basic endowment insurance for urban employees,and hopes to provide a decisionmaking reference for the construction of the endowment insurance system for common prosperity.Based on theoretical analysis and practical investigation,this paper uses macro modeling and micro empirical methods to explore the income redistribution effect of basic pension insurance expansion,and further explores the promotion effect of expansion in the face of common prosperity.It is found that: first,the income redistribution effect of the expansion of basic endowment insurance is reflected in the two links of payment and payment,there is a "reverse adjustment" effect in the payment link,and there is a "positive adjustment" effect in the payment link;In terms of sub-accounts,the pooled account has the effect of income redistribution,while the individual account does not.Second,the expansion of basic endowment insurance has a positive adjustment income redistribution effect,and will increase with the decrease of the proportion of personal wages in the pension treatment base,and weaken with the increase of social pooling rates;Among the three types of people,the positive adjustment effect of the expansion of basic endowment insurance to migrant workers is the most significant.Third,from the overall point of view,the expansion of basic endowment insurance can effectively reduce the Gini coefficient of enterprise employees and flexible employees,and narrow the income gap of employees;From a vertical point of view,the expansion of basic endowment insurance can realize the intragenerational redistribution of different income groups,and improve the income situation of low-and middle-income groups.From a horizontal point of view,there are regional differences in the income redistribution effect of the expansion of basic endowment insurance,and the income redistribution effect is the strongest in the western and northeastern regions.Fourth,from the results of the common prosperity evaluation,the expansion of basic endowment insurance will help promote common prosperity and improve people’s living standards.Based on the above conclusions,in order to better play the function of pension insurance income redistribution and ensure the orderly progress of the expansion work,the government should improve the basic endowment insurance system,appropriately adjust the contribution base,contribution ratio and pension treatment base of non-enterprise employees,and introduce insurance subsidy policies for low-income or unemployed groups.The innovation of this paper is mainly reflected in: first,the perspective innovation,different from the existing research only focus on the income redistribution effect of pension insurance payment and payment,this paper analyzes the redistribution effect of basic pension insurance on different types of employees from the perspective of expansion.Second,content innovation,not only macro modeling to investigate the impact of the expansion of basic endowment insurance on the income redistribution value of three types of employees,but also micro empirical evidence to test the income redistribution effect of the expansion of basic endowment insurance from the whole,horizontal and vertical levels.Third,the conclusion is innovative,through the construction of common prosperity evaluation indicators,this paper concludes that the expansion of basic endowment insurance can effectively promote common prosperity.
