公共行政领域在发展过程中不仅受到严谨、科学的实证研究的影响,还受到具有批判性和建设性的规范研究的影响。在两者交叉影响下,西方公共行政学呈现出管理主义与宪政主义不断碰撞交融的特点。实证研究因过分强调技术与理性饱受质疑,规范研究因过分沉迷体系构建而广受批判。在公共行政研究中,实证研究与规范研究都应发挥其应有的作用,两者应相互融合,以形成一种促进公共行政更好地发展的方法。 The field of public administration is influenced not only by rigorous and scientific empirical research in the development process, but also by critically and constructively normative research. Under the influence of the two, Western public administration shows the characteristics of continuous collision and collision of management and constitutionalism. Empirical research is over-emphasized that technology and rationality have been questioned, normative research has been widely criticized for its over-indulgence system. In the study of public administration, the research of positivism and norms should all play their due role, and the two should integrate with each other to form a method to promote the better development of public administration.
