为揭示我国人口出生率随地域分布的特点,本文以2003年、2006年、2009年、2012年、2015年、2017年六个时间段全国31个省市自治区的人口出生率数据为基础,研究从2003年到2017年这一时期内各省市人口出生率的整体变化情况,并通过热点分析、莫兰指数( Moran’s I)来反映人口出生率的空间聚集性和空间相关性,通过分析人口出生率重心的迁移过程来反映空间异质性.结果表明:我国各省市人口出生率的空间聚集性显著,主要集中在东部和西部地区,且人口出生率呈现出西部地区明显高于东部地区的特点;通过人口出生率重心迁移规律可以看出,在2003年至2017年期间,我国人口出生率重心整体向东移动.根据以上结论,国家应合理制定生育政策,因地制宜,从多方面出发来解决我国人口出生率低以及老龄化基数大的问题.
