Since the Treaty of Lisbon, national parliamentary chambers in the European Union can issue reasoned opinions on legislative proposals by the European Commission. These individual reasoned opinions lead to a review if at least one third of all chambers raise such concerns. Hence, coordination among parliaments is key. Using advances in inferential network analysis, this article infers the underlying diffusion pathways among national parliaments through which chambers are related to each other in their decisions to raise subsidiarity concerns. The emerging diffusion network is characterised by a compartmentalization into communities of European Union budget net contributor and net recipient countries. This descriptive finding has implications for the institutional effectiveness and aspired democratic legitimacy of the Early Warning System. A multivariate statistical network analysis confirms that diffusion occurs among net recipient countries and that weak institutions follow the lead of strong institutions in the Early Warning System.

欧盟预警系统中各国议会之间的潜在扩散网络

自《里斯本条约》以来，欧盟各国议会可以就欧盟委员会的立法提案发表合理的意见。如果所有商会中至少有三分之一提出此类担忧，这些个人推理意见将导致审查。因此，议会之间的协调是关键。本文利用推理网络分析的进展，推断各国议会之间的潜在传播途径，通过这些途径，各议院在决定提出附属问题时相互关联。新兴的传播网络的特点是划分为欧盟预算净捐助国和净接受国社区。这一描述性发现对预警系统的机构有效性和渴望的民主合法性具有影响。
