治理出生性别比偏高的新思路

The New Ideal for Declining High Sex Ratio at Birth

本研究发现在社会变迁过程中农村男孩偏好存在极大的区域差异,在无男孩偏好或弱男孩偏好的长江流域、东北农村,生育控制政策降低生育率的同时并没有导致严重的出生性别比偏高;而在男孩偏好强烈的华南农村,生育控制政策使这些地区成为出生性别比偏高的重灾区;华北的男孩偏好与出生性别比介于二者之间。在清理生育政策与出生性别比之间有条件性的关联机制的基础上,我们提出分区域治理出生性别比偏高的新思路。

This research shows that in the social change process of China,there are significant regional differences of son preference which affects the relationship between sex ratio at birth（SRB） and the control policy.The regions with highest SRB are mainly distributed on South of China,which regions has a strong clan tradition and son preference.There is lowest SRB in Yangtze River Basin and Three provinces in Northeast China;the son preference at these regions is weak.The SRB and son preference in North China Plain is between the up two regions.Based on the conditional correlation mechanism between the SRB and the birth control policy,we put forward the new ideas that reduce the high SRB should be in different ways for different regions.
