摘要
在推进共同富裕背景下,中国中等收入群体规模加速扩张,但基尼系数仍居高不下,收入分配不均衡问题依然严峻,中国中等收入群体的规模和质量需进一步探究。基于CFPS2010—2018年的调查数据,测度不同层面的中等收入群体规模变化及持续韧度,构建多维度质量评价指标体系,追踪规模扩张及韧度差距背后的质量差异,并实证检验其作用。研究表明:(1)城乡和不同受雇类型的群体间中等收入群体规模增速存在较大差距,中等收入群体的整体持续韧度较差;(2)中等收入群体规模扩张速度较快和持续韧度较好的群体,在财产、就业和人力资本方面的质量均具有较大优势,财产质量尤为明显;(3)财产、就业和人力资本方面的质量均会显著正向影响中等收入群体规模的增速和持续韧度,且财产质量的影响作用较大。研究结果不仅有助于明晰中等收入群体的规模与质量,也为促进中等收入群体的“提质扩容”和推进共同富裕进程提供政策启示。
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.
