摘要
家庭结构指家庭内个体特征的组合与相互作用方式。当前对收入变动与规模收入分配的研究大多从家庭整体或个体角度出发,尚欠缺从家庭结构变动角度的分析。研究家庭结构变动对家庭收入变动的影响有助于将家庭与个体层面的收入分配研究联系起来。该文从家庭内部入手,分解家庭结构变动对收入分配造成的影响,探寻家庭收入变动的关键因素。选取CHNS数据,结合年龄结构、收入结构、规模结构和知识结构四个维度构建了回归分析与分解模型。运用分位数回归和反事实分解方法,计算家庭结构变动对不同收入水平家庭的收入变动影响。分析发现,我国家庭结构变动对家庭收入变动的影响主要表现在知识结构、年龄结构和收入结构三方面,且存在明显的城乡差异和贫富差异。教育水平是推动整体家庭收入提升的主要因素,但不同收入水平家庭的教育回报率差异也导致了家庭收入差异的扩大。
Household Structure stands for various type of individuals＇combinations and interactions within a household. This article analyzes how changing household structure influence the household income by using CHNS （China Health and Nutrition Survey） dataset. The household structure covers four parts, including age structure, income structure, scale structure and knowledge structure. I firstly divide the time period into two parts contains of 1989--2000 and 2000--2001, in order to calculate the total influence of household structure on household income, by means of constructing counterfactual income distribution with MM decomposition method （Machado and Mata, 2005）. Then I use unconditional quantile regression with re-- centered influence function to decompose the contribution of each part of household structure. As a result, with other variables controlled, the knowledge structure, age structure and income structure turn out to be the key factor leading to the rising income inequality among different households, and knowledge structure and age structure exert effect mainly on middle--income groups.
