【摘要】：自党的十八大以来,“中国梦”成为了继“和谐社会”以来的又一个热门话题。“中国梦”的核心目标是实现“两个百年目标”,即全面实现小康社会和实现中华民族伟大复兴。但是,不管是哪个目标,首先必须确保的是社会收入分配的公平与合理性,具体表现为促进中等收入人口的比重,即“中等收入群体”。本文主要围绕“中等收入群体”,研究了以下几个方面： (1)中等收入群体的定义。本文主要从城乡结构、经济收入、职业结构以及动态角度综合分析,给出了中等收入群体的定义：在特定地域与时间范围内,收入除了能满足温饱状态外,还具有稳定的收入来源,依靠自身能力完全可以改变自己处境的,与社会发展极度协调的一个动态性的群体。 (2)洛伦兹模型构造以及证明。本文以洛伦兹曲线L(p)的充要条件L(0)=0、L(1)=1、L'(p)≥0.L"(p)≥0为出发点,构造了满足充要条件的七个模型L1(p)、L2(p)、L3(p)、L4(p)、L5(p)、L6(p)和L7(p)。并对L1(p)、L2(p)、L3(p)三个模型加以了证明。 (3)洛伦兹模型的参数拟合以及优劣。在引入模型拟合精度好坏的三个评判标准条件下,本文对模型进行了收入分配分组数据下的参数拟合,得出评判标准下的最优模型为L4(p)。 (4)中等人口度量的两种方法以及改进。在已知“收入空间法”与“人口空间法”定义的条件下,为了方便实证分析,本文做出具体的假设和改进。 (5)中等收入定位与人口度量的实证分析。实证分析,本文进行了同一地区连续两年内中等收入比重的横向分析与不同地区同一年份的纵向分析。综合以上几个方面的研究,在已知A、B两地区收入分配的分组数据情况下,得出的主要结论为：“收入空间法”与“人口空间法”分析的结果基本上是一致的；这个一致体现在中等收入人口比重差别不大；横向比较下中等收入人口比重都呈下降趋势；纵向比较下结果显示地区B的中等收入人口比重明显高于地区A。
[Abstract]:Since the 18th Party Congress, Chinese Dream has become another hot topic after harmonious Society. The core goal of "Chinese Dream" is to realize the "two hundred years' goal", that is, to realize the well-off society and the great rejuvenation of the Chinese nation in an all-round way. However, no matter which goal it is, the first thing we must ensure is the fairness and rationality of social income distribution, which is embodied in promoting the proportion of middle income population, that is, "middle income group". This paper focuses on the "middle-income group", and studies the following aspects: Definition of middle-income group. Based on the comprehensive analysis of urban and rural structure, economic income, occupation structure and dynamic angle, this paper gives the definition of middle income group: in particular region and time range, income can satisfy the condition of food and clothing. There is also a stable source of income, relying on their own ability to completely change their own situation, extremely coordinated with social development of a dynamic group. Construction and proof of Lorentz model. In this paper, based on the necessary and sufficient condition of the Lorentz curve LJ), the seven models L _ (1) P ~ (2) ~ (L ~ (2) ~ (2) ~ (1) and L _ (7) p ~ (1) ~ (?) L _ (1) and L _ (7) are constructed, which satisfy the necessary and sufficient conditions for the seven models L _ (1) and L _ (2) ~ (1) ~ (2) ~ (1) and L _ (7). The three models of L _ (1) ~ (1) ~ (1) ~ (1) ~ (?) ~ (1) were proved. 3) the parameter fitting of Lorentz model and its merits and demerits. Under the condition of introducing three criteria of model fitting accuracy, this paper carries out the parameter fitting of the model under the income distribution grouping data, and concludes that the optimal model under the evaluation standard is L4. (4) two methods of measuring the middle population and their improvement. Under the conditions of known definitions of "income space method" and "population space method", in order to facilitate empirical analysis, this paper makes specific assumptions and improvements. (5) empirical analysis of middle income orientation and population measurement. Based on the empirical analysis, this paper makes a horizontal analysis of the proportion of middle income in the same region for two consecutive years and a longitudinal analysis of different regions in the same year. Based on the above studies, the main conclusions are as follows: the results of the analysis of "income space method" and "population space method" are basically consistent; The result of vertical comparison shows that the proportion of middle income population in area B is obviously higher than that in area A.
