使用多水平模型对1992—1997年中国妇女人工流产行为进行了分析,目的是考察和检验宏观（省级水平）和微观（个人水平）因素对中国妇女分孕次人工流产概率的独立影响及其显著性。多水平模型在模拟具有层次结构性的数据上要优于传统的回归模型,在社会科学领域正在被越来越广泛地应用。多水平模型结果显示:无论是宏观因素还是微观因素,都对妇女人工流产有独立而显著的影响,微观影响在所有孕次都是显著的,而宏观影响则取决于孕次。同时宏观因素对微观上的人工流产社会经济差异也具有显著影响,并与孕次有很大关系。本文的多水平模型有助于全面认识我国妇女人工流产的影响因素。
The multi-level model was used to analyze the Chinese women’s abortion from 1992 to 1997 with the purpose of examining and testing the independent influence of macro (provincial level) and micro (individual level) factors on Chinese women’s second-tripartite abortion probabilities and their Significance. Multi-level models are superior to traditional regression models in simulating hierarchically structured data and are being applied more and more widely in the social sciences. Multi-level model results show that both macroeconomic factors and microeconomic factors have an independent and significant effect on women’s abortion. The microeconomic impact is significant at all pregnancies, while the macroeconomic impact depends on the number of pregnancies. At the same time, the macroeconomic factors also have a significant impact on the socioeconomic differences of microscopic abortion, and have a great relationship with gestational age. The multi-level model of this article helps to fully understand the influencing factors of women’s induced abortion in our country.
