到底是什么影响了恩格尔系数——基于多因素的经济学和OLS分析

摘要

近年来,恩格尔系数连续走低却时而反弹的怪现象引起了国内的关注,人们迫切地想要了解到底是什么原因导致了这些现象,因此研究恩格尔系数的影响因素变得很有必要。本文运用经济学和计量学的理论与方法,从经济发展、收入差距、物价变动三个因素入手,跨学科、多因素地分析其对恩格尔系数的影响因素和机制,并通过定性和定量分析,结合国家十二五规划纲要,针对如何实质性地降低恩格尔系数、提高人民生活水平提出相关参考建议。%In recent years,the strange phenomenon of continuous decline but sometimes rebound of the Engel Coefficient has aroused public attention.As a result,they urgently want to know what in the end leads to these strange phenomena.Therefore,its necessary to conduct a study of the influencing factors of the Engel Coefficient.In this paper,we make multidisciplinary and multi-factor analysis of the factors and mechanisms of Economics and Metrology which exert an impact on the Engel Coefficient from three aspects-economic development,income disparity and price changes.With regard to the Twelfth National Five-Year Plan,we put forward some suggestions on how to reduce the Engel Coefficient and improve living standards substantially through qualitative and quantitative analysis.
