Abstract: Based on the unbalanced panel data of China Family Panel Studies (CFPS) 2010-2016, this paper constructs a Double Fuzzy Breakpoint Regression Model to conduct an empirical study of the spillover effect of spouse retirement on personal health and the influencing mechanism of family care in it under different window widths. The results show that spouse retirement has significantly improved the male self-assessed health by 28%~44.3%, and significantly reduced the female self-assessed health by about 32%. The affecting mechanism is that after the retirement of spouse, the husband can get more care from his spouse, while the wife can care more for her husband though her income decreases. The spillover effect of spouse retirement on men's and women's mental health is manifested as a positive effect, and the frequency of exercise is the main affecting mechanism. As for male and female suffering from chronic diseases, spouse retirement has no significant effect. The government should pay attention to the role of family care in health care, give retired female elderly more health management services and health care education, launch family physical exercise programs, support and encourage retired young male to return to the labor market, implement progressively delayed retirement policy, and gradually popularize the Smart Home Care.

Key words: spillover effect, health, retirement policy, family care
