This article introduces a new data set on the access of transnational actors (TNAs) to international organizations (IOs). While IOs were long the exclusive preserve of member governments, recent decades have witnessed a shift toward more inclusive forms of governance, involving participation by non-governmental organizations, philanthropic foundations, multinational corporations, and other forms of TNAs. Yet existing research has lacked the data necessary to map this phenomenon and its variation over dimensions such as time, issue areas, and world regions. The TRANSACCESS data set is designed for this purpose and contains information on the level of openness in 298 bodies of 50 IOs from 1950 to 2010. On the basis of this data set, we also introduce a first quantitative measure of institutional openness in the shape of a composite index, available at both the IO and body levels. This index can be used to compare TNA access across and within IOs but also as a variable in large-N studies on global and regional governance, where IO openness is potentially relevant.

跨国进入国际组织的机会1950–2010：新数据集

本文介绍了有关跨国参与者（TNA）与国际组织（IOs）的访问的新数据集。虽然IO长期以来一直是成员国政府的专有财产，但近几十年来见证了向更具包容性的治理形式的转变，包括非政府组织，慈善基金会，跨国公司和其他形式的TNA的参与。然而，现有研究缺乏绘制这种现象及其在时间，问题区域和世界区域等维度上变化的必要数据。TRANSACCESS数据集就是为此目的而设计的，其中包含有关1950年至2010年期间298个50个IO机构的开放程度的信息。在此数据集的基础上，我们还以以下形式介绍了制度开放的第一个定量度量：综合指数 在IO和主体级别均可用。此索引可用于比较IO之间和内部的TNA访问，但也可作为有关N和开放程度可能与之相关的有关全球和区域治理的大型N研究的变量。
