摘要: 扩大中等收入群体是实现共同富裕的重要手段。本文在梳理中等收入群体定义与测度标准的基础上,探索利用宏观统计数据测度中等收入群体比重的统计方法并借以探寻中等收入群体规模变化的内在规律。基于世界银行发布的统计数据,本文测度127个国家(地区)的中等收入群体比重与分布特征,并着重对中等收入群体比重与基尼系数之间的关系展开探究,以此归纳中等收入群体的合理比重及共同富裕背景下扩大中等收入群体的内在逻辑。最后,本文利用我国2003—2021年数据对中等收入群体比重进行测度,并对其变动效应进行定量分析,据此研判我国扩大中等收入群体的实践路径,为我国新发展阶段以扩大中等收入群体为抓手推进共同富裕提供客观依据。

Abstract: Expanding the middle-income group is an important means to achieve common prosperity. Based on the definition and measurement criteria of middle-income groups, a statistical method to measure the share of the middle-income group using macro statistics is proposed and used to explore the inner pattern of changes in the size of the middle-income group. The paper measures the share and distribution characteristics of middle-income groups in 127 countries and regions based on the statistics released by the World Bank and focuses on the relationship between the share of middle-income group and the Gini coefficient, to summarize the reasonable share of middle-income group and the internal logic of expanding middle-income group in the context of common prosperity. The paper also measures the share of middle-income group and quantitatively analyzes its change effects using the data from 2003 to 2021 in China. Based on this, the practical path of expanding the middle-income group is analyzed to provide an objective basis for promoting common prosperity by expanding the middle-income group in the new development stage of China.
