This paper studies the effect of infant death on subsequent fertility in a developing country, examining spacing of children and additional births following the survival or death of the preceding infant. The material is provided by the 1971 National Fertility Survey of Korea, 23,635 retrospective birth records of 6,285 women. The findings suggest that prior to the introduction of a national family planning program, the influence of infant death was limited to the biological effect resulting from a shortened lactational period. Since fertility regulation methods have been made available throughout the country, motivational effects to replace the lost child appeared to emerge. The proportion of excess births attributable to infant deaths has increased in recent years. However, because of the lowered infant mortality, the overall impact of infant death on the national fertility level appears to be small.
本文研究了发展中国家婴儿死亡对随后生育的影响，考察了前一个婴儿存活或死亡后孩子的生育间隔和额外生育情况。资料来源于1971年韩国全国生育调查，有6285名妇女的23635份回顾性生育记录。研究结果表明，在国家计划生育项目实施之前，婴儿死亡的影响仅限于哺乳期缩短所产生的生物学效应。自从全国范围内有了生育调节方法后，似乎出现了为弥补夭折孩子而产生的生育动机效应。近年来，因婴儿死亡导致的额外生育比例有所增加。然而，由于婴儿死亡率降低，婴儿死亡对全国生育水平的总体影响似乎较小。
