This paper aims at shedding light on partisan differences in forest policy by analysing whether governing parties' policy outputs are strongly orientated towards the demands of the nature conservation or the forestry sector. The data base encompasses four forest-related issues, relevant from 2001 to 2018 in the 16 German Bundesländer, so that more than 50 cabinets were able to be considered for analysis. The application of Qualitative Comparative Analysis allowed testing for several variables that were expected to have an impact on or even dominate partisan effects in certain configurations. The findings show that political parties do matter in forest policy. While the Green Party's policy outputs are clearly orientated towards nature conservation demands, the Christian Democratic Union/ Christian Social Union is a suitable ally for the forestry sector. The Social Democrats are between these two extremes, but closer to nature conservation in highly populated Bundesländer. Factors like forest cover or share of private forests were revealed not to be as important as political parties. We conclude that research in forest policy missed an important political factor of forest policy by neglecting the influence of political parties as a research subject.

本文旨在通过分析执政党的政策输出是否强烈地面向自然保护或林业部门的需求，从而阐明森林政策的党派差异。该数据库包含 2001 年至 2018 年在 16 个德国联邦，因此可以考虑对 50 多个机柜进行分析。定性比较分析的应用允许测试几个变量，这些变量预计会影响或什至主导某些配置中的党派效应。调查结果表明，政党在森林政策中确实很重要。虽然绿党的政策产出明显面向自然保护需求，但基督教民主联盟/基督教社会联盟是林业部门的合适盟友。社会民主党介于这两个极端之间，但在人口稠密的德国更接近自然保护. 森林覆盖率或私人森林份额等因素被证明不如政党重要。我们得出结论，森林政策研究忽略了作为研究对象的政党的影响，从而错过了森林政策的一个重要政治因素。
