公共管理学作为一门系统的管理学科,是在一定的社会历史条件下把管理学理论与多种学科的知识运用于公共事务的管理过程中产生的。公共管理学渊源于美国的行政学,经历了行政管理、公共行政、政策科学及新公共管理等诸多阶段。与当今公事事务密切联系的公共管理学其自身也有由各个流派推动,形成了百家争鸣的繁荣景象。 As a systematic discipline of management, public management science is produced by using the theory of management and the knowledge of many disciplines in the management of public affairs under certain social and historical conditions. Public administration originated from American administration and experienced many stages such as administration, public administration, policy science and new public administration. Public administration, which is closely related to the current affairs of the public affairs, has itself been promoted by all schools and formed a prosperous scene with a hundred schools of thought.
