中文摘要:
      在学术界对恩格尔定律普遍达成共识,并主要关注恩格尔系数外部影响因素的背景下,本文对共识性的恩格尔定律提出悖论情形,从恩格尔定律与需求收入弹性的本质性关系出发,运用数理推导等定性定量方法对悖论情形进行了验证。然后,引入收入分解理论的份额思想,运用收入来源结构的面板数据,采用混合固定效应模型和随机效应模型,对恩格尔定律悖论情形内部机理进行分析,得出了支持恩格尔定律悖论情形的分项收入作用机制。
英文摘要:
      The academia reaches the consensus about Engel’s Law, and most of existing researches focus on the external influence factors of Engel’s Coefficient. This paper has proposed the paradox situation for the consensus Engel’s Law. The qualitative and quantitative methods such as mathematical derivation are used to verify the paradox situation based on the essential relationship between Engel’s Law and the Income Elasticity of Demand. Then, this paper has adopted Fixed Effect Model and Random Effect Model to analyze the internal mechanism of Engel’s Law paradox situation by following the theory of Income Inequality Decomposition and by the panel data of income source. Finally, the paper draws a sub-income mechanism of action that supports the paradox situation of Engel’s Law.
