摘要：
Under the background of implementing the national strategy to actively respond to the aging population and the urbanization strategy, it is of great practical significance to study the internal relationship between city size and the health of the elderly. Therefore, based on CFPS data and city level data, we use instrumental variable of wall area of Qing Dynasty and the parameter estimation method based on distribution functions to identify the effect of city size on the health. We find that there is a positive causal relationship between city size and the health of the elderly. Big cities can significantly improve the health by three channels: Income effect, social participation effect and medical security effect. Among them, the contribution of medical security effect and social participation effect is higher. Heterogeneity analysis shows that big cities basically meet the health needs of the elderly with different income and education, which do not exacerbate the health inequality among the elderly. However, the household registration system restricts the floating elderly population from obtaining health benefits from big cities. In addition, the crowding effect reflected by population density and transportation cost has negative impact on health, especially in cities with population of more than 5 million, which should be paid attention to. © 2022 Systems Engineering Society of China.
