中国作为一个发展中大国,它所面临的人口问题已经得到了广泛的关注。虽然,在强硬政策下,人口数量能够得到一定控制,但是家庭所拥有的孩子及预期拥有的适度孩子数量究竟是多少,单纯地依靠人口政策可能力度不够,如果家庭的孩子数量影响到家庭的效用及其负效用,那么家庭就会慎重考虑适度孩子的数量。所以说要实现家庭效用最大化,就必定要涉及到家庭中孩子的数量,保证家庭孩子的适度数量,就成为了理性家庭所面临的也是必须要解决的重要问题。因此,本文根据家庭效用最大化的理论,得出家庭收入的高低会对家庭孩子的数量产生一定影响,同时,家庭对人力资本投入档次,也会对家庭决定孩子的数量起到一定作用的结论。从而为以后人口政策导向提供了重要理论依据。
As a large developing country, China has received widespread attention for its population issue. Although population can be controlled under hard-line policy, what is the number of children in the family and the appropriate number of children expected to have? Simply relying on population policy may not be sufficient. If the number of children in the family affects the effectiveness of the family And its negative utility, then the family will carefully consider the number of moderate children. Therefore, if we want to maximize the effectiveness of the family, it must involve the number of children in the family and ensure that the proper number of children in the family becomes an important issue that rational families must face and must solve. Therefore, based on the theory of maximizing family utility, this paper draws the conclusion that the level of family income will have an impact on the number of children in the family. At the same time, the family’s investment in human capital will also play a role in the family’s decision on the number of children . Thus providing an important theoretical basis for future population policy guidance.
