【摘要】：文章基于贝克尔的孩子质量数量替代理论,构建了三期OLG模型,考察了家庭对孩子质量和数量的选择及两者间的替代关系,并对收入在其中的作用做了理论分析,最后利用中国健康和营养调查(CHNS)数据,进行了实证检验,并得出结论:孩子数与家庭收入负相关,收入的变化对低收入家庭尤其是中等收入家庭的孩子数的影响更为显著;孩子质量与家庭收入正相关;除了位于收入最顶层的富裕家庭外,孩子的质量与数量间存在普遍的替代关系,且收入越低,替代程度越高。
[Abstract]:Based on Becker's theory of children's quality and quantity substitution, this paper constructs a three-phase OLG model, examines the choice of children's quality and quantity and the substitution relationship between them, and makes a theoretical analysis on the role of income in the choice of children's quality and quantity. Finally, by using CHNSdata of China Health and Nutrition Survey, the author makes an empirical test, and concludes that the number of children is negatively correlated with family income, and the change of income has a more significant effect on the number of children in low-income families, especially in middle-income families; The quality of children is positively related to family income; in addition to the wealthiest families at the top of the income, there is a general substitution relationship between the quality and quantity of children, and the lower the income, the higher the degree of substitution.
