从1990年到2005年，国际合作（以共同作者关系衡量）在论文数量上呈线性增长，但在国际地址数量上呈指数级增长。这证实了Alfreson et al.的[沃森，O.，Glanzel，W.，& Danell，R.（2004年）。膨胀的文献计量学价值：科学合作的作用和评价研究中相对指标的需要。Scientometrics，60（3），421 - 432]国际合作中通货膨胀的假设。国际科学合作的模式可以被视为网络效应，因为除了欧洲委员会的倡议之外，没有政治机构在这一级调解关系。国际层面的科学与其他复杂的适应性系统有着共同的特征，后者的秩序来自于数百个追求自利策略的主体的相互作用。在2000 - 2005年期间，全球合作网络似乎加强了由14个最合作国家组成的核心小组。由于这些国家拥有强大的国家系统，预计这一核心小组将非常有效地利用来自全球网络的知识。边缘国家可能因核心国家实力增强而处于不利地位。(C)2008爱思唯尔有限公司保留所有权利。
International collaboration as measured by co-authorship relations on refereed papers grew linearly from 1990 to 2005 in terms of the number of papers, but exponentially in terms of the number of international addresses. This confirms Persson et al.' s [ Persson, O., Glanzel, W., & Danell, R. (2004). Inflationary bibliometrics values: The role of scientific collaboration and the need for relative indicators in evaluative studies. Scientometrics, 60(3), 421 - 432] hypothesis of an inflation in international collaboration. Patterns in international collaboration in science can be considered as network effects, since there is no political institution mediating relationships at that level except for the initiatives of the European Commission. Science at the international level shares features with other complex adaptive systems whose order arises from the interactions of hundreds of agents pursuing self-interested strategies. During the period 2000 - 2005, the network of global collaborations appears to have reinforced the formation of a core group of fourteen most cooperative countries. This core group can be expected to use knowledge from the global network with great efficiency, since these countries have strong national systems. Countries at the periphery may be disadvantaged by the increased strength of the core. (C) 2008 Elsevier Ltd. All rights reserved.
