近年来,消费者价格尤其是食品价格波动起伏较大,为恩格尔系数反映居民真实生活水平带来许多不利因素。消费者价格如何影响恩格尔系数,两者之间存在什么样的内在联系,这正是本文所要研究的内容。一、国内外文献综述1.国外文献。Wing Thye Wooetal(2011)以中国城镇住户调查数据为样本,恩格尔系数和收入水平之间存在着相互验证的关系,在最低收入、低收入、较低收入、中等收入、上中等 In recent years, consumer prices, especially food prices, have fluctuated greatly, bringing many unfavorable factors to reflect the real living standards of residents due to the Engel’s coefficient. How consumer prices affect the Engel’s Coefficient, what kind of internal relations exist between them, and this is exactly what we want to study.
