The purpose of the study is to discuss the ongoing debate on the future of the EU, with reference to the scenarios formulated by the European Commission, as well as other interesting concepts, and to indicate the most probable scenario that the EU would follow. The method used in the research is studies of the scientific publications, comparison and evaluation of alternative integration scenarios and interpretation of selected legal issues related to the division of competences between the EU and the Member States (MS). The main tasks are as follows: (i) to prove that the concurrent debate about the future of the EU is not “new” and similar questions were asked since the birth of the integration processes, (ii) the usage of sovereignty concept to interpret different demand for integration of the MS, (iii) identification of links between globalisation, integration and the crisis as well as (iv) comparisons of different scenarios related to further (dis)integration within the EU and their consequences. The novelty of the paper is that it relates the integration scenarios formulated by the European Commission to the issue of sovereignty as well as to historical and legal background of the European integration. Out of the possible scenarios proposed, multi-speed Europe is the most probable one. The real challenge, if this scenario will evolve, is to safeguard the possibility for the “lagging countries”, to join the (more integrated) leaders – if the former will be ready to do so. The challenge is to make the multi-speed Europe – an inclusive concept. Multiple speeds have in fact existed within the EU, as there always have been and will be those who are the laggards and the leaders. The awareness of the European issues has been increasing, as suggested by De Wilde & Zurn (2012). However, the EU will go through serious changes, consequences of which deserve thorough debate in order to disseminate knowledge on the consequences of the strategic choices ahead of the MS.

整合的利与弊。欧洲的解体方案

该研究的目的是参考欧盟委员会制定的方案以及其他有趣的概念，讨论有关欧盟未来的正在进行的辩论，并指出欧盟将遵循的最可能方案。研究中使用的方法是研究科学出版物，比较和评估替代整合方案以及解释与欧盟和成员国之间权限分配有关的选定法律问题。主要任务如下：（i）证明关于欧盟未来的并发辩论不是“新的”，并且自一体化进程诞生以来就提出了类似的问题；（ii）使用主权概念来解释对MS集成的不同需求，（iii）查明全球化，一体化与危机之间的联系，以及（iv）比较与欧盟内部进一步（解）一体化及其后果有关的不同情况。该文件的新颖之处在于，它把欧洲委员会制定的一体化方案与主权问题以及欧洲一体化的历史和法律背景联系起来。在提出的可能方案中，多速欧洲是最可能的方案。如果这种情况会发生演变，则真正的挑战是维护“落后国家”的可能性，加入（更加一体化的）领导人-如果前者愿意的话。挑战在于使多速欧洲成为一个包容性概念。实际上，欧盟内部存在多种速度，一如既往，并将成为落后者和领导人。正如De Wilde＆Zurn（2012）所建议的那样，人们对欧洲问题的认识一直在提高。但是，欧盟将经历严重的变革，其后果值得彻底辩论，以便在MS之前传播有关战略选择后果的知识。DOI：http：//dx.doi.org/10.5755/j01.eis.0.11.18955
