Abstract: The system of expert argumentation and evaluation for administrative decisions is to improve the science of government decisions,avoid the randomness of the decisions and promote the interactivity between the government and the public.However,in the process of applying the system,there exists the problem of the expert failures,namely,the misplacement of the expert roles,the rational limitation of the expert views and the exceeding participation of the expert.The causes for these problems are the inappropriate establishment and structure of the expert group,the lack of proper procedures in the expert argumentation and evaluation as well as the inadequate stipulation of the expert right and obligation.The system of expert argumentation and evaluation for administrative decisions should be restructured and improved by maintaining the independence of the expert consultancy and argumentation,guaranteeing the unity of the rights and obligations of the expert and ensuring the effectiveness of the expert argumentation and evaluation.

Key words: administrative decisions, the system of expert argumentation and evaluation
