人口大流迁时期区域人口统计指标的效度失真

The Statistic Distortion of Demographic Data Caused by Mass Migration

20世纪80年代以来,中国一直处于一个史无前例的人口大流迁时期。区域间大规模的人口流迁不仅对中国社会经济的发展和人口布局带来了巨大变化,而且还对传统的人口统计与分析方法带来一系列新的问题。文章认为,大规模的人口流迁不仅会造成一系列区域人口统计指标的效度失真,同时还会导致一系列与人口有关的社会经济统计指标的效度失真。

China has been undergoing an unprecedented massive population movement since the 1980’s. A large scale of floating and migratory population has brought about not only many changes in China’s socio-economic development and population distribution but also a series of newproblems in utilizing the traditional demographic statistics. The paper shows that the massive floating and migratory population has led to both the functional distortions of regional demographic indicators and of population-related social and economic indicators.
