本研究的主要目的是阐述国际科学合著关系中的民族特征。本文试图找到合著链接中对称性和非对称性的统计证据，以及国际合著性与国家研究概况和引文影响之间的关系。在1995/96年度最活跃的50个国家的国内和国际合著出版物的相对专业化中，可以区分四种基本类型，说明这两种情况的差异的重要性。合著地图揭示了过去十年国际合著联系的结构性变化。除了稳定的链路和连贯的簇，还发现了新的节点和链路。并非各个国家之间的所有联系都是对称的。在几个国家也可以检测到特定的(单向)合著亲和力。正如预期的那样，国际合著平均导致出版物的引用率高于纯国内论文。然而，国际合作对国家引文影响的影响在不同国家之间差异很大(在一个国家内不同领域)。然而，在某些情况下，对其中一方甚至对双方都没有引用优势。
The main objective of this study is the elaboration of national characteristics in international scientific co-authorship relations. An attempt is made to find statistical evidence of symmetry and asymmetry in co-publication links, of the relation between international co-authorship and both national research profiles and citation impact. Four basic types can be distinguished in the relative specialisation of domestic and internationally co-authored publications of 50 most active countries in 1995/96 concerning the significance of the difference between the two profiles.Co-publication maps reveal structural changes in international co-authorship links in the last decade. Besides stable links and coherent clusters, new nodes and links have also been found. Not all links between individual countries are symmetric. Specific (unidirectional) co-authorship affinity could also be detected in several countries.As expected, international co-authorship, on an average, results in publications with higher citation rates than purely domestic papers. However, the influence of international collaboration on the national citation impact varies considerably between the countries (and within one individual country between fields). In some cases there is, however, no citation advantage for one or even for both partners.
