【摘要】：文章引入分析子代与父代收入位置对比的绝对和相对指标,借助双向排序法,利用对南疆地区15年的跟踪调查数据,分析了民族地区代际收入流动性特征,并使用因素分解法对影响代际收入流动性变化的因素及其影响程度进行研究。研究结果表明:(1)子女收入排序与父母收入排序近乎完全线性关系,即南疆地区收入流动性具有很强的代际传递特征;(2)南疆地区低收入家庭代际传递具有较强的固化特征,且有向中等收入家庭延伸态势,而高收入家庭绝对流动性得以保持,因而有贫富分化加剧趋势;(3)远离城市的乡镇其代际收入流动性更低,喀什市作为唯一的地级市,其代际收入流动性最高;(4)父代受教育年限、少数民族身份、工资性收入和地区经济发展水平对家庭收入流动性有显著影响,且因家庭收入分位数不同影响程度存在差异。
[Abstract]:This paper introduces absolute and relative indexes to analyze the position of income of offspring and father, and by means of bidirectional sorting method, analyzes the characteristics of intergenerational income mobility in ethnic minority areas by using the data of 15 years' follow-up investigation in southern Xinjiang. The factor decomposition method is used to study the influence factors and degree of intergenerational income mobility. The results show that: (1) the relationship between income ranking of children and parents' income ranking is almost completely linear, that is, income mobility in southern Xinjiang has strong intergenerational transmission characteristics, and (2) intergenerational transmission of low-income families in southern Xinjiang has strong solidification characteristics. Moreover, it extends to middle income families, while the absolute mobility of high income families is maintained, so there is a tendency of increasing polarization between the rich and the poor. (3) the intergenerational income mobility of villages and towns far away from the city is even lower, and Kashi is the only prefecture-level city. The intergenerational income mobility is the highest; (4) the paternal education years, minority identity, wage income and regional economic development level have significant influence on the family income mobility, and there are differences in the degree of influence according to the household income quantile.
