Under the background of new liberal arts, the construction of public management discipline should be based on the social times, the goal of talent cultivation, and the characteristics of the discipline itself, so as to meet the requirements of new liberal arts. In terms of social background, the public management discipline should not only respond to the new problems arising from the technological revolution, but also to the problems of national governance in the new era. In terms of the goal of talent cultivation, the public management discipline should not only cultivate public management professionals but also undertake the basic task of establishing virtue and cultivating talents. In terms of the characteristics of the discipline itself, the public management discipline should highlight the functional advantages of humanistic education, comprehensive discipline, and social service.
