摘要
文章依据恩格尔系数对中国中产阶层的现状进行描述性统计分析,并采用非参数角度的核密度估计对中产阶层的比重进行测度,最后将函数性数据分析方法引入中产阶层的变迁之中,进而找出中产阶层发展的规律。
According to Engel's coefficient, this paper makes a descriptive statistical analysis on the present situation of the middle class in China, and measures the proportion of the middle class by using nonparametric nuclear density estimation. Finally,the functional data analysis method is introduced into the changes of the middle class, and the law of the middle class development is found out.
