针对中等收入者在现代社会中的重要作用和当前中等收入者研究方法不足的状况,本文基于现代非参数方法中的核密度佑计方法,提出测算中等收入者比重及其变动的新方法,并构建影响中等收入者比重变动的因素动态分解方法。依据居民收入的微观调查数据,本文提出我国中等收入的绝对标准和相对标准,对我国中等收入者的比重及变动情况进行测度,并对影响我国中等收入者比重变动的增长效应、分配效应和水平效应进行分解。在理论和实证研究基础上,得到有政策指导意义的结论。
In view of the important role of middle-income people in modern society and the current research methods of middle-income earners, this paper proposes a new method to measure the proportion of middle-income earners and their changes based on the method of nuclear density blessing in modern non-parametric methods. Constructing a Dynamic Decomposition Method to Influence the Change of the Proportion of Middle - earners. Based on the micro-survey data of residents’ income, this paper puts forward the absolute standard and relative standard of middle-income in our country, and measures the proportion and changes of middle-income people in our country. It also analyzes the growth effect, distribution effect and level Effect decomposition. On the basis of theoretical and empirical research, we get the conclusion that there is policy guidance.
