Migration Experiences and Reproductive Behaviors:An Analysis Based on Fertility Diffusion Theory
China's fertility transition process is characterized by a regionally progressive pattern.The process of fertility transition exhibits both temporal and spatial diffusion phenomena,with migrant flows serving as a crucial channel for fertility diffusion.Using data from the Life History Survey of the China Health and Retirement Longitudinal Study(CHARLS)2014 and provincial fertility data,this paper exam-ines the relationship between fertility environment changes resulting from inter-provincial migration and women's number of children ever born and reproductive behaviors.The analysis reveals that migration experiences from high-fertility regions to low-fertility regions reduce the lifetime number of children.Mi-gration experiences in relatively low-fertility regions significantly decrease the probability of giving birth.This indicates that changes in the fertility environment serve as a critical pathway through which migra-tion experiences shape reproductive behaviors.In the context of large-scale population migration from rural to urban areas and from central and western to eastern regions,this study provides a micro-level explanation for the diffusion phenomena observed in China's fertility level changes.
