Résumé : Measuring factors affecting scientific productivity is an issue that often draws attention of the scientific community and policy-makers. In Vietnam, the studies about this have just begun for a few years with limited data. Especially, there has been little understanding about what affects the performance on the social sciences research publication productivity yet. This research, using OLS method, analyses the data of 406 Vietnamese social scientists in Scopus within a period of 2008-2017. The results confirm the impact of work environments shown in the varying degrees of influence of collaborations on scientific output β au.ttl(Uni ) = 0.183 , P < 0.0001; andβ au.ttl( Ins) = 0.042 , P < 0.0001( N = 406). However, in the high-performance group, the magnitude of the effects drops by 27%, while the benefits of collaborating are also reduced by 30.6% or 42.9%, depending on the type of work environments. International collaborations can boost both sheer total number of publications (β au. fc = 2.778; P < 0.0001) and adjusted productivity (β au. fc = 1.626 ; P < 0.0001). Nevertheless, increment in the number of unique foreign collaborators only raises the authors’ number of published works (β au. fr(ttlitems) = 0.322 ; P < 0.0001) but doesn’t improve the contribution of Vietnamese scientists (β au. fr(cp) = 0.066 ; P = 0.30).
