In this context, how to do a good job in the education and teaching of the discipline of public administration, so that the education concept and teaching mode of the discipline can meet the strategic demands of the development of the new era and the social needs of talent training, which has become a major issue faced by colleges and universities and teachers in the process of education and teaching. Therefore, through the analysis of the current training mode of public administration talents in colleges and universities, this paper explores the specific strategies for the establishment and optimization of the practical teaching system of public administration talents under the background of innovation and entrepreneurship.展开更多
