摘要 居民收入水平不同,恩格尔系数也不同,因此收入分配对社会总体恩格尔系数的影响是不确定的。基于马斯洛层次需求理论证明边际食品消费倾向递减,并且当消费函数为线性或近似线性时,收入差距扩大会降低恩格尔系数。基于省际面板数据的实证分析表明,中国居民边际食品消费倾向递减且消费函数为(近似)线性,居民收入差距扩大降低了居民恩格尔系数(基尼系数升高对恩格尔系数下降的贡献率为22%),从而出现"分配越不平等,居民总体生活水平越高"的矛盾现象。因此在使用总体指标评价居民生活水平时,收入分配指标必须得到同等的重视;在经济发展中,公平和效率必须兼顾才能实现居民福利最大化。 This paper based on the assumption of the utility function, prove that when the M_PC of food decreasing and the consumption function is linear or nearly linear, the widening income gap will reduce the Engel coefficient. Chinese residents inter-provincial panel data-based empirical analysis also shows that Chinese residents' MPC of food decreasing and the consumption function is (approximate) linear. Then residents' income gap had widened to reduce our residents' Engel coefficient and to improve residents' overall standard of living; and thus give rise to the paradox of "distribution more unequal, and residents of the higher overall standard of living. " Therefore, when we use the overall indicators to evaluate the standard of living, the income distribution indicators must be given equal attention; in economic development, equity and efficiency must take into account in order to truly maximize the residents' welfare.
