摘　　要：本文利用中国第五次人口普查1‰抽样数据,以城镇区域人口为重点,定量分析了农村人口流动对城镇地区人口出生性别比,以及农村流入城镇人口子女性别的影响。研究发现,中国农村未流动人口、农村流入城镇人口和城镇非农村流入人口的出生性别比均偏离了出生性别比的正常水平,农村人口流动影响了城镇地区生育性别,农村流入城镇人口相对较强的男孩偏好观念加剧了城镇地区出生性别比偏高。Based on the sample data from the 5^th censns of China, this paper analyzes the effects of ruralurban migration on the sex ratio at birth in urban regions, and the sex ratio of rural-urban migrants＇ children in China. The results shows that the sex ratio at birth of the rural-urban migrants appears to be significantly higher than the normal, and so do the sex ratio of the non-migrants in rural or urban areas. Rural-urban migration has significant effects on the sex ratio at birth in urban regions.To some extent, strong son preference among the rural-urban migrants has exacerbated high sex ratio at birth in urban regions.
