The construction of the concept of Chinese Public Administration must include the whole history of the development of administration science in the past hundred years. It is incorrect to ignore or mistakenly confuse the basic knowledge of the development of administrative science during the period of 1921-1949, and only the academic thought that the 1980s was the starting point of Chinese Public Administration studies. The development of administrative science during this period was marked by the publication of Jiang Kangli's "The Principle of Public Administration" in 1933, which not only outlined a picture of Chinese academics, but also formed a vigorous momentum in introduction, reference and learning. More importantly, it has promoted the continuous maturity of the concept of modern government in China and promoted the development of administrative practice with the administrative efficiency movement as the core. This is a new revaluation, which is helpful for Chinese Public Administration to recognize its academic status in the new era, and to better obtain new discoveries and development.
