农村二孩生育间隔的分层模型研究

2001年全国计划生育/生殖健康调查数据本质上是分层结构性质的,其中包括妇女个人数据和村级数据两个层次,比较适合采用分层模型分析。本文应用分层线性模型分析了这一原始数据,考察宏观的社会经济环境及计划生育氛围与微观的妇女个人特征如何共同影响二孩生育间隔。

Second Birth Intervals in Rural China: An HLM Analysis

Using the original data of 2001 National Family Planning/Reproductive Health Survey, this paper investigates how the community-level and individual-level characteristics affect the length of second birth intervals in rural China. Hierarchical linear models are applied for this purpose, as the 2001 survey data essentially are of a nested structure entailing multilevel approaches. Results show that community-level variance accounts for more than one-third of the total variance of the second birth intervals, and there are evident constraints of the community-level determinants on the individual-level variables.
