The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization.

科学挑战日益复杂，需要国内外日益紧密的研究合作。由此产生的趋势不仅影响产生新知识的方式，而且还影响其在科学界的传播方式。本文分析了一个国家的科学生产的“国际化程度”与相关引用出版物之间的关系。实证分析基于2010-2012年意大利出版物。研究结果表明：i）被引用的可能性随着研究团队国际化程度的提高而增加；ii）整个国内的研究团队倾向于在更大程度上引用整个国内的出版物；iii）反之亦然，由国际合作产生的出版物往往被更多的外国出版物而不是包括国内作者的出版物引用。这些结果在整体和学科层面上都显现出来。研究结果可能会为针对国际化的研究政策提供参考。
