To identify the characteristics of optimal research environment for postdoctoral researchers, we examine research papers produced by postdoctoral researchers in relation to their postdoctoral contexts. We find a difference by researcher’s environment in papers where the target postdoctoral researcher is not the first author. In particular, the number of papers where the first author belongs to other institutes from the target postdoctoral researchers is quite different. Furthermore, coauthored papers in the postdoctoral researchers are correlated with differences in the H-index, that shows both the productivity and the citation impact of each researcher’s publications. This survey by institutional research indicates that collaboration during postdoctoral research may affect the future research career of those researchers.
