中国出生性别比失衡现状及原因探究中文摘要
2000年第五次人口普查数据显示，中国80%以上的省、自治区、直辖市的出生人口性别比超出正常值域，部分地区高达130以上。这意味着我国出生的婴儿中，每100个女婴对应着130个男婴。假设这种态势继续延续下去，我国人口性别比例将极度失衡，将引发重大社会问题。本文采用实证分析的研究方法，通过对历年人口普查资料的分析，总结出生人口性别比失衡现状，并探索现象发生背后的原因。

Abstract
In 2000, the fifth census data shows that the sex ratio at birth of the provinces, autonomous regions, and municipalities in China more than 80% is beyond the normal range. Some areas are over 30%. This means that our babies were born in every 100 baby girls corresponds to 130 baby boys. If this trend continues down, the population sex ratio in China will be extremely unbalanced, then it will cause serious social problem. Based on empirical analysis method, through the analysis of census data of calendar year, this paper summarizes the situation of the current birth population sex rations imbalance and explores the reasons behind the phenomenon.
