Abstract：Overwork is a typical phenomenon in developing countries, especially in China, and also a significant issue that restricts the high-quality development of labor markets. Based on the China Migrants Dynamic Survey (CMDS), this study empirically tests the impact of health right's accessibility on migrant workers' overwork and its intergenerational differences using the quantile-on-quantile regression (QQR) method, thereby providing a new explanation for overwork. The results show that: first, health rights' accessibility significantly reduces migrant workers' overwork, with a 1-unit improvement correlating with a 4.22% decline in overwork rate and 2.36-hour weekly reduction in overwork hours. Second, the inhibitory effect is significantly stronger among new-generation migrants compared with first-generation counterparts. Third, threshold sensitivity exists: significant impacts emerge only when accessibility exceeds 0.4 for first-generation and 0.2 for new-generation migrants. But excessive health rights' accessibility paradoxically increases migrants' labor supply. Finally, accessibility policies for health rights are generally inefficient in underdeveloped cities.
