近年来,我国城乡居民的恩格尔系数都有很大程度的下降,从系数值看,城市远低于农村。而上海市则是相反,农村居民的恩格尔系数值却低于城市。围绕这个问题,我们进行了初步研究。如下图所示,上海城市居民的恩格尔系数已经由1995年的53%下降到了2004年的36%;而乡村居民的恩格尔系数 In recent years, the Engel coefficient of urban and rural residents in our country have declined to a great extent. From the value of coefficient, the city is much lower than that in rural areas. In Shanghai, on the contrary, the Engel’s coefficient of rural residents is lower than that of cities. Around this issue, we conducted a preliminary study. As shown in the figure below, the Engel’s coefficient for Shanghai urban residents has dropped from 53% in 1995 to 36% in 2004; while the Engel’s coefficient for rural residents
