摘　　要：本文从收入不平等的角度探寻需求不足的成因和内在影响机制,研究发现总体有效需求水平在收入不平等对经济增长的影响中起到中介效应的作用。采用理论模型中的家庭收入结构性参数值表示收入不平等程度,这区别于传统使用基尼系数方法来测度收入差距水平。基于2000-2019年30个国家面板数据,模拟出家庭收入结构性参数并设定为核心解释变量,对家庭收入结构性参数、总体有效需求水平与人均GDP增长率的影响关系进行了相关分析。结果发现:家庭收入结构性参数的增大将引致总体有效需求水平的下降进而限制经济可持续增长,家庭收入结构性参数与人均GDP增长率呈现出显著的负相关关系。收入不平等程度的持续扩大对总体有效需求的持续增长形成限制性约束,总体有效需求不足的形成进一步限制总体经济的持续增长。这方面的研究为理解当前国内外需求不足和后工业化阶段增长现象提供了一个新的视角。From the perspective of income inequality, this paper explores the causes of insufficient demand and the internal impact mechanism. The study finds that the overall effective demand level plays a mediating role in the impact of income inequality on economic growth. The value of structural parameters of household income in the theoretical model is used to indicate the degree of income inequality, which is different from the traditional use of the Gini coefficient method to measure the level of income disparity. Based on the panel data of 30 countries from 2000 to 2019, the structural parameters of household income were simulated and set as core explanatory variables, and the relationship between structural parameters of household income, the overall effective demand level and the growth rate of per capita GDP was analyzed. The empirical results revealed that the increase in structural parameters of household income will lead to a decline in the overall effective demand level and thus limit sustainable economic growth. The structural parameters of household income have a significant negative relationship with the growth rate of per capita GDP. The continuous expansion of increasing income inequality has restricted the continuous growth of overall effective demand, and the formation of insufficient overall effective demand further restricts the continuous growth of the overall economy. The research in this area provides a new perspective for understanding the current insufficient domestic and foreign demand and the growth phenomenon in the post-industrialization stage.
