Abstract: This paper estimates the city-level prevention and control efficiency of COVID-19 with a nonparametric method. We find a significant but heterogeneous effect of prevention policy among China’ s cities, and the difference in urban physician resources is the main explanation for such heterogeneity. The urban health care professionals have a greater marginal effect on COVID-19 containment in the cities where they are in relative scarcity. The input of medical materials including hospitals and hospital beds has no marginal effect on disease control, which indicates that medical materials do not reach a constraint state. Further analysis of doctors’ occupational structure finds that the role of clinicians is more critical than the other types of doctors. In cities where emergency response starts earlier, doctors play a more important role in improving prevention and control efficiency. Therefore, government policy is a safeguard for the doctors to play their role. The COVID-19 reveals that China’s health care human resources need to be improved.
