Healthy city construction is an important and effective way to implement the healthy China strategy and promote the healthy China action. The results of the 2020 National Healthy City Assessment show that 27 of the 31 comparable indicators of the participating cities are higher than the national level in the same period or in the near future；Of the 32 indicators comparable to the national target value，26 have exceeded the national target value for 2020. The results of the comprehensive index of healthy cities show that the overall level of the cities participating in the evaluation is at the middle level，and 71 cities have reached the upper middle level. In general，the construction of healthy cities in the cities under evaluation has made remarkable progress and achievements，but the national work is uneven and there are some weak links. At present，all localities should take the construction of healthy cities as the starting point to promote the construction of a healthy China，adhere to the health promotion and prevention oriented strategy，establish and improve the government led，multi sectoral cooperation，and the whole society participation working mechanism，start from the governance of health influencing factors，promote the integration of health into all policies，and comprehensively improve the level of health governance. Relevant departments and professional institutions should strengthen the research on healthy city construction，especially in response to key health problems，mass mobilization and participation，and evaluation of the effect of healthy city construction.
