Policy advice has been the subject of ongoing research in the policy sciences as it raises fundamental issues about what constitutes policy knowledge, expertise, and their effects on policymaking. This introduction reviews the existing literature on the subject and introduces the themes motivating the articles in the issue. It highlights the need to consider several key subjects in the topic in the contemporary era: namely the challenge of legitimacy, that of values, and the challenge of politics. The papers in the issue shed light on the ongoing delegitimization of conventional knowledge providers, the problem of the normative basis of experts’ advice, the increasing politicization of expertise in policymaking, and the relevance of political context in influencing not only the role of experts but also whether or not their advice is accepted and implemented. It is argued that these modern challenges, when not addressed, reinforce trends toward the inclusion of antidemocratic values and uninformed ideas in contemporary policymaking.

应对政策建议中的合法性、价值观和政治挑战

政策建议一直是政策科学持续研究的主题，因为它提出了关于什么构成政策知识、专业知识及其对政策制定的影响的基本问题。本引言回顾了有关该主题的现有文献，并介绍了本期文章的主题。它强调了需要考虑当代主题中的几个关键主题：即合法性的挑战、价值观的挑战和政治的挑战。本期的论文揭示了传统知识提供者持续的非法化、专家建议的规范基础问题、决策专业知识日益政治化、政治背景的相关性不仅影响专家的作用，而且影响他们的建议是否被接受和实施。有人认为，这些现代挑战如果不得到解决，就会强化当代政策制定中纳入反民主价值观和无知思想的趋势。
