Statistical relationships between corresponding authorship, international co-authorship and citation impact of national research systems

摘要: This paper presents a statistical analysis of the relationship between three science indicators applied in earlier bibliometric studies, namely research leadership based on corresponding authorship, international collaboration using co-authorship data, and field-normalized citation impact. Indicators at level countries are extracted from SIR database created by SCImago Research Group publication records indexed for Elsevier's Scopus. The authorship citation-based is found to be complex, as it reflects country's phase scientific development coverage policy database. Moreover, one should distinguish genuine effect purely due fractional counting. Further analyses institutions qualitative validation studies recommended.
