Abstract

This paper investigates how population aging influences the skill income gap via two pathways: the skill supply and skill-biased technical changes. Utilizing both simple and multiple mediating effects models for empirical analysis, this paper discovers that an increase in the old-age dependency ratio and a decrease in the child dependency ratio both elevate the relative supply of skilled labor and intensify skill-biased technical changes. These changes result in a dual effect: the augmented skilled labor supply reduces the skill income gap, whereas the enhanced skill-biased technical changes raise it. Among these two mechanisms, the impact of skill supply emerges as slightly more significant.

人口老龄化与技能收入差距的动态变化：多重中介效应分析

本文研究了人口老龄化如何通过两个途径影响技能收入差距：技能供给和技能偏向的技术变化。本文利用简单中介效应模型和多重中介效应模型进行实证分析，发现老年抚养比的增加和少儿抚养比的降低都会提高技能劳动力的相对供给，并加剧技能偏向的技术变化。这些变化产生了双重效应：熟练劳动力供给的增加缩小了技能收入差距，而技能偏向技术变化的加强则拉大了这一差距。在这两种机制中，技能供给的影响稍显重要。
