Public health is an indispensable part of the field of public management. At the national health and health conference, general secretary Xi proposed that "without national health, there is no national well-off society", which undoubtedly reflects the significance of public health in building a well-off society in an all-round way. Based on the dimensions of policy tools, policy norms and policy objectives, 235 public health policy texts were sorted, counted and analyzed by using content analysis method and nvivo11 analysis software. The conclusion of the study is that among the policy tools used in policy-making in the field of public health, there is an imbalance in the system of policy tools, the use of supply-oriented policy tools is too frequent, the use of demand-oriented policy tools is absent, and the use of environmental policy tools is relatively insufficient; In the dimension of policy norms, advocacy norms occupy a dominant position and realize the transformation from prohibitive norms to advocacy norms. In the dimension of policy objectives, the attention to public health service objectives and public health security objectives is relatively balanced. Based on the above conclusions, this paper puts forward relevant policy suggestions.
