中文摘要：

基于课题组2009年进行的全国四个主要城市化地区12个大中小城市流动人口调查的微观数据，考察了流动人口的生育意愿和性别偏好，特别是研究了影响流动人口生育意愿的决定因素。流动人口同城市人口在生育数量偏好上已经不存在明显差距，但性别偏好观念上仍有显著差异；较农村人口，流动人口生育数量偏好明显要小，男孩偏好也要弱。流动人口的年龄、性别、婚姻状况、受教育程度、健康状况、工作类型和居住类型对生育意愿有显著影响。

英文摘要：

Based on a 2009 survey of 2400 migrants in 12 cities across 4 China＇ s major urbani- zing areas, we investigate the migrants＇ fertility and son preference and the determinants of these preferences. We find migrants now have fertility preferences close to those of urban resi- dents while they still have significant son preference on average. However, migrants have both lower fertility and son preference compared to China＇ s rural residents. Regression - based a- nalysis indicates that the age, education, gender, marriage status, health and employment type all have impacts on migrants＇ s fertility and son preference.
