摘要：This paper, which is based on the five major economies of European Union , France, Germany, Holland, Luxembourg, Sweden and United Kingdom, is dedicated to the empirical analysis on synchronization of economic fluctuation in the European Union (EU). The research conclusions show that during the period spanning from 1971-2016, the synchronization of EU economic fluctuations is significant, while the deepening of regional integration witnesses the gradual enhancement of the synchronization in the EU. Meanwhile, the research also shows that some dis-synchronization has been existing within EU, which indicates the presence of the discordance in EU economic policies and regional cooperative mechanism.
