Abstract In order to realize the characteristics of collaboration and output in scientific research, propose improvements to research collaboration models, increase collaboration awareness, help scientific researchers choose better research partners, establish an efficient research collaboration network, improve academic research output, and promote scientific development. This study uses 200 high-yielding authors in the field of international medical informatics as an example to conduct a literature review, and social network, bibliometric, statistical analyses. First, a correlation analysis is carried out to investigate the relationships among measurement indicators of scientific research output, such as the number of articles, number of articles cited, h-index, and number of papers whose citation exceeds a certain eigenvalue n, and scientific research collaboration indicators such as point degree, intermediary center, structural hole, collaboration ability index, collaboration degree, collaboration rate, and collaboration coefficient. Then, the principal component analysis method is adopted to extract the common factors. Finally, using the newly constructed scientific research output measurement index as the dependent variable and the scientific research collaboration measurement index as the independent variable, a multivariate statistical analysis is undertaken. The results show that the phenomenon of scientific research collaboration in the field of medical informatics is increasingly common. Under different collaboration modes, there are differences in the distribution of scientific research output of scholars. The increase in the number of fixed collaborations between authors does not reflect the high degree of heterogeneity among the cooperating groups. If researchers want to improve scientific research output, they should focus on establishing a stable and high-frequency collaboration model with partners and strive to cooperate with researchers from different disciplines to improve partner diversity.
