Scale Measurement and Quality Tracking of Middle-income Groups in China in the Context of Common Prosperity
In the context of promoting common prosperity,the scale of middle-income group in China is rapidly expanding.However,the Gini coefficient of income distribution remains persistently high,exceeding the international caution line for a long time,signifying a pressing issue of income inequality.Therefore,while the middle-income group is undergoing rapid expansion,it is imperative to further investigate the quality of the expansion.Based on continuous tracking survey data from CFPS 2010-2018,constructing a multidimensional quality evaluation indicator system.Utilizing a cooperative approach involving information entropy weights and the multiplication method of independent weights,the study tracks the quality differences behind the scale expansion and resilience gaps,and provides empirical evidence of their effects.It reveals as the following:(1)The overall scale of the middle-income group is rapidly expanding,but there are significant differences in the growth rates between urban and rural groups and various employment types.Most middle-income groups transition between low and middle incomes,with relatively short cycles of sustaining middle-income status and overall poor resilience;(2)Groups with fast-expanding scale and good resilience among the middle-income group have significant advantages in terms of property,employment,and human capital.The quality of property,in particular,is notably distinct;(3)The quality of property,employment,and human capital will all significantly positively impact the growth rate and resilience of the middle-income group,with property quality playing a particularly significant role.The study results not only contribute to a clearer understanding of the scale and quality of the middle-income group in China but also provide policy implications for promoting the"quality and quantity expansion"of the middle-income group and advancing the common prosperity process in China.
