Following the outbreak of the Great Financial Crisis, numerous reforms were conducted in all areas of the European Union (EU)’s Economic and Monetary Union. These reforms aimed at strengthening the resilience of Member States’ economies after they had been put under severe strain by the crisis. They included, among others, the reinforcement of the efforts toward economic coordination in the framework of the European Semester for economic policy coordination, or the creation of the European Banking Union after which competences in the areas of banking supervision and bank resolution have been transferred to the European level. More than a decade after the Great Financial Crisis however, several of these reforms are still underway. This article is an introduction to this Special Issue whose contributions examine the reforms performed to date, as well as those that are currently under discussion, from the perspectives of multilevel (administrative) cooperation and the resort to soft law instruments. Indeed, the procedures newly devised rely heavily on the effective cooperation between national and European institutions as well as on a variety of soft law instruments.

金融危机爆发后，欧盟（EU）经济和货币联盟的各个领域都进行了多次改革。这些改革旨在加强成员国经济在遭受危机严重压力后的复原力。其中包括加强在欧洲学期经济政策协调框架内进行经济协调的努力，或建立欧洲银行业联盟，之后银行监管和银行处置领域的权限已转移到欧洲水平。然而，在大金融危机发生十多年后，其中一些改革仍在进行中。这篇文章是对这个特刊的介绍，他的贡献审查了迄今为止进行的改革，以及目前正在讨论的那些，从多层次（行政）合作和诉诸软法律文书的角度来看。事实上，新设计的程序在很大程度上依赖于国家和欧洲机构之间的有效合作以及各种软法律文书。
