Finland conducted the first nationwide field experiment with partial basic income between 2017 and 2018. The experiment and its results were widely reported in international media and featured in political debates across the globe. Domestically, the experiment had an impact on social policy debates but no impact on social policy. For example, it did not feature in the Social Security 2030 project or in the work of the Social Security Reform Committee (2020–2027). The research setting for the experiment was compromised from the beginning due to political reasons; but the scientific power was further undermined by a new sanctioning model, which was implemented in 2018 at the beginning of the second year of the basic income experiment. The new Government taking office in 2019 promised to continue with a negative income tax experiment; however, no such experiment was conducted. The article will unpack these developments in Finland and discuss possible explanations for denouncing basic income as a policy idea.

芬兰在 2017 年至 2018 年期间进行了第一次全国性的部分基本收入实地实验。该实验及其结果在国际媒体上得到广泛报道，并在全球政治辩论中出现。在国内，该实验对社会政策辩论产生了影响，但对社会政策没有影响。例如，它没有出现在社会保障 2030 项目或社会保障改革委员会（2020-2027 年）的工作中。由于政治原因，实验的研究设置从一开始就受到了损害；但在 2018 年基本收入实验第二年开始时实施的新制裁模式进一步削弱了科学力量。2019年上任的新政府承诺继续进行负所得税实验；然而，没有进行过这样的实验。本文将解读芬兰的这些发展，并讨论谴责基本收入是一种政策理念的可能解释。
