The paper presents the results of the study of international and national cooperation of Ukrainian scientists from different scientific fields using citation analysis data from Scopus in the period of 2011-2015. The results show that during the period under study, the number of documents of highly cited Ukrainian scientists that have received enough citations to be included to the top 1%, 5% and 10% most cited documents in the world, evidenced an increase and were significantly different in different subjects areas. Papers written by a group of co-authors predominate among highly cited documents of Ukrainian scientists. Consequently, international cooperation plays an important role in Ukrainian scientist's research visibility and impact. At the same time, up to 16%-27% highly cited articles of Ukrainian scientists have been written without partnering with foreign colleagues, that means a significant part of important scientific research in Ukraine are carried out by oneself. Therefore, for generating an optimal policy of science development in Ukraine it is important to provide a balanced view of the expectations of the results of the international cooperation of Ukrainian scientists and achieving a required balance between the inter-country and international collaboration.

乌克兰科学家合作撰写的高被引论文：文献计量分析（2011-2015）

本文介绍了使用来自 Scopus 的 2011-2015 年期间的引文分析数据，对来自不同科学领域的乌克兰科学家的国际和国家合作研究的结果。结果表明，在研究期间，被引用次数足够多的乌克兰科学家的文献数量被列入世界上被引用次数最多的前 1%、5% 和 10% 的文献中，并且出现了增长。不同学科领域有显着差异。由一组合著者撰写的论文在乌克兰科学家的高引用文献中占主导地位。因此，国际合作在乌克兰科学家的研究知名度和影响方面发挥着重要作用。同时，高达 16%-27% 的乌克兰科学家的高引用文章是在没有与外国同事合作的情况下撰写的，这意味着乌克兰重要科学研究的很大一部分是自己进行的。因此，为了在乌克兰制定最佳的科学发展政策，重要的是要平衡看待乌克兰科学家国际合作结果的期望，并在国家间和国际合作之间实现所需的平衡。
