From the perspective of theoretical research, what are the important contributions of new public administration to the development of contemporary public administration?

From the perspective of theoretical research, the contributions of new public administration mainly include the following points:

First of all, it transcends the research mode of positivism. The new public administration learns from hermeneutics and critical theory, emphasizes effective communication and ideological emancipation under democratic administration, and pays attention to meaning and value, thus getting rid of the shackles of the traditional "rational model".

Second, the independent development of administrative science is moving forward. From 1950 to 1970, administration became a vassal of politics and management. After the rise of new public administration, it is no longer limited to the research orientation of system and technology, but tries to be independent from politics and management. The establishment of many specialized administrative research institutions and societies is a typical example of the independent development of public administration.

Third, the scope of public management has expanded. The new public administration has carefully studied and defined the meaning and scope of "public". It focuses on establishing public philosophy and advocating democratic administration, which not only expands the research scope of public administration, but also expands the rights and responsibilities of public administration practitioners.

Fourthly, the content of administrative organization theory has been improved. The research scope of traditional administrative theory is too narrow and empty, while the scholars of new public administration redefine the purpose and significance of administrative organization, endow it with normative basis and put forward the direction of theoretical construction.

Fifth, the content of administrative education has been deepened. In the past, most of the administrative personnel trained according to the traditional administrative theory were "efficiency robots", while the new public administration scholars emphasized the need to cultivate an administrative generalist with both ability and political integrity, foresight and initiative. From the perspective of administrative practice, the new public administration theory, based on the principle of social justice, puts forward ideas and propositions such as reducing hierarchical constraints, decentralization, participation, democratic administration, actively responding to public needs and face-to-face communication, which has had a great impact on contemporary America in terms of equal distribution of public services, liberation of civil servants' rights, diversification of interests and value representatives, enhancement of participation concept, establishment of introspective ethical awareness and decentralization of personnel management.
