约翰·巴里在他写的欧洲、全球化和可持续发展，“到目前为止，没有一个单一的、无所不包的理论的欧化，甚至它的基本意义仍然是有争议的”[ 7 ]。然而，巴里指出，“主流的看法是，欧化的研究应设法了解国内影响欧洲一体化”[ 8 ]。作为一种文化现象，欧化是激烈的，尤其是在最近扩大包括罗马尼亚和许多东欧集团的意图使用声明的光。此外，土耳其加入欧盟的问题引出的欧化和适用于成员的问题。不同于全球化，欧化是如此流畅的暧昧，矛盾的标准，往往在任期内实施。巴里指出，“一些欧化的过程定义的影响来自欧洲的决定和影响成员国的政策和政治和行政结构”；别人“简单地描述为一个“过程的国内政策领域越来越受到欧洲政策制定[ 9 ]。如果这确实是欧化的目的，比其他任何国家，无论是在美洲，亚洲，或非洲，可以成为“欧化”。在一个足够大的规模，甚至可以认为，如果有足够的世界各国政府安排考虑欧洲利益的政策，那么“欧化”成为帝国主义征服，其中共享共同的方面全球化但在崔波诺经典问题根本不同，或“谁受益。”巴里认为，根据“欧洲化上述概念化的逻辑，“整个思想关注“过程中通过欧洲一体化的渗透和在某些情况下带来的调整国内的研究所机构、决策程序和公共政策.
John Barry writes in his Europe, Globalization, and Sustainable Development that “to date, there is no single, all-encompassing ‘theory of Europeanization, and even its basic meaning remains contested”. However, Barry notes that the “mainstream opinion is that Europeanization research should seek to understand the domestic impacts of European integration”. As a cultural phenomenon, Europeanization is hotly contested, especially in light of the recent enlargement including Romania and the declaration of much of the Eastern bloc’s intent to apply. Moreover, the question of Turkish EU accession begs the question of Europeanization and its applicability to members. Unlike globalisation, Europeanization is so fluidly ambiguous that contradicting criteria are often implemented in the term. Barry states that “some define Europeanization as ‘the process of influence deriving from European decisions and impacting member states’ policies and political and administrative structures”; others “simply describe it as a “process whereby domestic policy areas become increasingly subject to European policy making. If this is indeed the purpose of Europeanization, than any nation, be it in the Americas, Asia, or Africa, can become “Europeanized.” On a large enough scale, it may even be contended that if enough of the world’s governments arrange their policies with European benefit in mind, then “Europeanization” becomes imperialist conquest, therein sharing aspects in common with globalisation but differing fundamentally in the classic question of cui bono, or “who benefits.” Barry contends that according to the logic of the aforementioned conceptualisation of “Europeanisation,” the entire idea concerns the “process through which European integration penetrates and in certain circumstances brings about adjustments to domestic institutions, decision-making procedures and public policies
