ABSTRACT This article aims to understand policy change by analyzing the external and internal events as well as actor resources, actor beliefs and coalitions. Empirically, we have selected the Swiss forest policy system and analyze two consecutive Swiss National Forest Programs and the related revision process of the forest law between 2004 and 2016. Exploring pathways of change according to the Advocacy Coalition Framework, we find that increased actor resources in the form of expertise, finances and political recognition alongside external and internal events – made the forest issue more salient – contribute to a successful policy change. These factors led to an altered actor coalition structure with less clear-cut positions and the shared recognition that change was necessary. The results show how Forest Policy Programs may increase their chances of producing policy change over time, as the first program failed to lead to policy change, while the second was successful.

政策变化和国家森林计划：瑞士在联盟、外部和内部事件方面的经验

摘要本文旨在通过分析外部和内部事件以及参与者资源、参与者信念和联盟来理解政策变化。根据经验，我们选择了瑞士森林政策体系，并分析了 2004 年至 2016 年间连续两次的瑞士国家森林计划和森林法的相关修订过程。根据倡导联盟框架探索变革路径，我们发现增加的行动者资源在专业知识、财务和政治认可以及外部和内部事件的形式——使森林问题更加突出——有助于成功的政策变革。这些因素导致行动者联盟结构发生了变化，立场不那么明确，并且大家都认识到必须做出改变。
