Social interaction and fertility dynamics

通过阐明四种社会相互作用机制对生育的影响，本研究有望为理解生育动态提供一个新的维度。既有理论研究，也有实践研究。从理论的角度，这项研究将对个体生育行为如何因社会互动机制而发生变化进行系统的回顾。从实践的角度来看，一种新的数学方法有望被提出，这种方法将被用来构建完整的、更现实的亲属关系结构，而不是基于稳定人口的方法。生育率和死亡率对家庭结构的影响将被表述和量化。最后，模拟模型将提供一种自下而上的方式，基于社会互动来理解生育率下降。将审查家庭政策的有效性，为政策制定者提供参考。

Through elucidating the effect of four social interaction mechanisms on fertility, this research is expected to provide a new dimension to understanding fertility dynamics. Both theoretical and practical investigations are involved. From a theoretical perspective, this research will provide a systematic review of how individual fertility behaviour changes due to social interaction mechanisms. From a practical perspective, a new mathematical method is expected to be proposed, which will be used to construct full and more realistic kinship structures than the stable-population-based approach. The effects of fertility and mortality on the kin structure will be formulated and quantified. Finally, the simulation models will provide a bottom-up way to understand fertility decline based on social interaction. The effectiveness of family policies will be examined, providing a point of reference for policymakers.
