Harmonisation and legal convergence are core tasks of the EU. This paper explores the question about the determinants for national convergence of EU law, specifically applied to the ever-growing body of European consumer sales law. The measurement of national convergence is based on a unique coding of five directives in seven Member States. Using the fuzzy-set Qualitative Comparative Analysis (fsQCA) method, the paper finds that differences in national convergence can partly be explained by favourable features of the corresponding directives; however, mainly, they are the result of a combination of domestic political factors and, to a lesser extent, the country characteristics. This has important policy implications, for instance, on the need to ‘bring in politics’ in the debate about convergence, harmonisation and consumer sales law.

什么决定了欧盟法律的国家趋同？衡量消费者销售法的实施情况

协调和法律趋同是欧盟的核心任务。本文探讨了有关欧盟法律国家趋同的决定因素的问题，特别适用于不断增长的欧洲消费者销售法主体。国家趋同性的衡量基于七个成员国的五个指令的独特编码。使用模糊集定性比较分析（fsQCA）方法，本文发现国家收敛的差异可以部分解释为相应指令的有利特征；然而，它们主要是国内政治因素以及在较小程度上是国家特点共同作用的结果。这具有重要的政策意义，例如，在关于趋同、协调和消费者销售法的辩论中需要“引入政治”。
