Overlapping Regionalism in Africa, the Americas, Asia and Europe Compared

在二战和冷战的余波中，各国加强了多边合作，与邻国的合作日益增多。今天，世界各地有70多个RO。当区域组织分享成员国和政策能力时，我们说的是重叠的地区主义。虽然最近出现了一个比较地区主义的研究议程，但重叠的地区主义还没有得到太多的学术关注。重叠的地区主义现象是普遍而重要的，尤其是因为区域组织的政策和规则可能是不相容的，并可能使区域组织的有效性失效。该项目有助于填补我们在以下三个研究问题方面对重叠区域主义的认识的空白：重叠区域主义是如何随时间和空间演变的？重叠的地区主义为什么会发生，什么时候会增加？各州如何应对重叠的地区主义，这是否会影响ROS的有效性？我们通过编制一个新颖而独特的数据库(1945-2015)，在一个全面的理论框架基础上发展一套假设，并用先进的方法分析重叠地区主义的驱动因素和后果来回答这些问题。

In the aftermaths of WWII and the Cold War, states have intensified multilateral collaboration and increasingly cooperated with states in their neighborhood. Today there are more than 70 ROs in all parts of world. When ROs share member states and policy competences, we speak of overlapping regionalism. While a comparative regionalism research agenda has been emerging recently, overlapping regionalism has not yet received much scholarly attention. The phenomenon of overlapping regionalism is widespread and important, not in the least since ROs’ policies and rules can be incompatible and might redue RO effectiveness. This project contributes towards filling gaps in our knowledge of overlapping regionalism in respect to three research questions: How has overlapping regionalism evolved over time and space? Why and when does overlapping regionalism occur and increase? How do states react to overlapping regionalism and does this affect the effectiveness of ROs? We answer these questions by compiling a novel and unique database (1945-2015), developing a set of hypotheses on the basis of a comprehensive theoretical framework, and analyzing drivers and consequences of overlapping regionalism with advanced methods.
