It has been widely perceived in South Korea that the rise in a woman's income is negative for her childbirth. This study tries to verify the hypothesis empirically because the Korean government initiated the basic plan for low fertility in 2006 and has constantly strengthened work–family balance policy since then. Our analysis using a household annual data over 18 years, 1999–2016, indicates that married women's economic power relates positively to childbirth for the period after 2006. We also find that the higher birth likelihood among top income quartile women is largely attributed to their better accessibility to maternity protection benefits. These findings imply that the government's efforts to support work–family balance have been successful to a certain extent. However, the benefits remain limited only to high-income women.

在韩国，人们普遍认为女性收入的增加不利于生育。本研究试图从经验上验证这一假设，因为韩国政府于 2006 年启动了低生育基本计划，并从那时起不断加强工作-家庭平衡政策。我们使用 1999 年至 2016 年 18 年间的家庭年度数据进行的分析表明，已婚妇女的经济实力与 2006 年之后的生育率呈正相关。我们还发现，高收入四分位女性的生育可能性较高主要归因于她们更好的生育能力。生育保护福利的可及性。这些发现表明，政府支持工作与家庭平衡的努力在一定程度上取得了成功。然而，这些好处仍然仅限于高收入女性。
