As the most basic public service，healthcare service is a necessary support to cultivate and strengthen the sense of national identity. This article utilizes the linear regression model based on data from the Comprehensive Survey of Chinese Social Conditions in 2021(CSS2021)to study the public awareness of the macro system of healthcare services and the physical practice in the treatment process on national identity. The study found that there was a significant positive correlation between the public perceptions of the macro system of healthcare services and national identity，which means the better the public perception of healthcare safety， healthcare equity and local government’s quality of healthcare services，the higher the public satisfaction of healthcare insurance，lead to higher sense of national identity. In terms of the physical practice in the process of public treatment，the choice of public medical institutions has a significant impact on national identity，and those who choose to go to public hospitals for treatment have a higher sense of national identity. The study did not find a significant relationship between the perceptions of medical institutions and national identity. We should consider healthcare governance as an essential window to test the modernization of the national governance system and governance capacity，starting from the public health promotion that continues to improve healthcare system capacity. We should also focus on ensuring fairness within the healthcare system and vigorously promote humanistic care，allowing the public to feel a sense of attainment，happiness and security in healthcare services，thus constantly generating national identification.
