尽管恩格尔系数在一定程度上仅揭示了特定发展阶段的收入和消费结构的关系, 在应用上有时有失真的现象, 但恩格尔系数作为衡量居民消费结构的指标, 一定程度上反映了今天居民生活水平的高低, 反映了一个国家生产水平和经济状况, 因此对恩格尔系数的研究具有一定的意义. 通过对数据的研究, 笔者发现城镇和农村居民恩格尔系数有如下变化规律: 整体呈下降趋势, 前期下降速度显著,后期下降速度减缓. 本文运用回归分析的方法对人均国内生产总值、城镇居民消费支出和农村居民消费支出三组数据建立模型, 预测出我国城镇和农村居民恩格尔系数并进行曲线拟合.

Although Engel's coefficient only reveals the relationship of between the income and consumption structure in certain degree, having the phenomenon of distortion in application, Engel's coefficient as a index of measuring resident's consumption structure, which to some extent reflects the peo-ple's living standard height, reflecting the level of production and economic conditions of a country.Therefore, researching the Engel's coefficient has cer-tain significance.Based researching the data, The author found that the change law is as follows:the urban and rural residents Engel's coefficient overall downward trend, the early rate of decline significantly, and the late slowed down.Through modeling the three groups of data that per capita GDP, urban consumption expenditure and rural consumer spending, using regression analysis predicts China's Engel coefficient of urban and rural residents and curving fitting.
