Although European integration has become an increasingly salient and controversial topic in domestic politics, the consequences of this politicisation of the European Union for the integration process have not received adequate scholarly attention. To fill this lacuna, this article devises five hypotheses on the effects of politicisation for the integration process, which are subsequently tested against the evidence of the Euro and Schengen crises. Both crises had comparable origins, but the Euro crisis caused substantial deepening of integration, while the Schengen crisis has not engendered any meaningful reforming steps. The empirical analysis finds that politicisation assumed different forms across the two crises, which is shown to be one causal factor that explains the variation in crises outcomes. The article thereby contributes to a multifaceted understanding of the politicisation of international institutions, EU integration theory and the dynamics of the Euro and Refugee crises.

比较欧元和申根危机期间欧盟一体化的政治化

尽管欧洲一体化已成为国内政治中一个日益突出和有争议的话题，但欧盟这种政治化对一体化进程的影响并没有得到足够的学术关注。为了填补这一空白，本文设计了五个关于政治化对一体化进程的影响的假设，随后将根据欧元和申根危机的证据对这些假设进行检验。两次危机的起源相似，但欧元危机导致了一体化的大幅深化，而申根危机并没有产生任何有意义的改革步骤。实证分析发现，政治化在两次危机中呈现出不同的形式，这被证明是解释危机结果变化的一个因果因素。
