In this paper, I focus on how national policy implementation affects policy revision at the EU level. The main argument is that when policy is implemented in a decentralized manner, it affects the current situation or status quo in member states. This affects the possibilities of any further legislative change at the EU level. The analyses suggests that heterogeneity in national preferences and homogeneity in national status quo points make it less easy to adopt a revised policy. This result is illustrated by the recent discussion on revising the Posting of Workers Directive. Having rather different views on this policy while faced with limited possibilities to shape this policy nationally, makes it difficult to change the Posting Directive. The rather long and difficult negotiations, especially among the member states, about its revision support this implication.

在本文中，我关注国家政策实施如何影响欧盟层面的政策修订。主要论点是，当政策以分散的方式实施时，它会影响成员国的现状或现状。这会影响欧盟层面任何进一步立法变化的可能性。分析表明，国家偏好的异质性和国家现状的同质性使得采用修订后的政策变得不那么容易。这一结果在最近关于修订《工人发布指令》的讨论中得到了说明。对这项政策有相当不同的看法，而在全国范围内制定这项政策的可能性有限，因此很难改变发布指令。相当漫长而艰难的谈判，尤其是成员国之间，
