The scientific research cooperation group centered on the authors of MURRAY C J L, ATUN R, MCKEE M, BHUTTA ZA, and MEARA JG has the closest communication. The details of the top 20 authors published papers are shown in Table 2.


**Table 2.** The Top 20 authors.

In Table 2, MURRAY C.J.L. is the scholar with the most significant number of published papers in global health research, with a degree value of 49 and an H-index of 120. MURRAY C.J.L. mainly focuses on global health burden research, global health international assistance, global health finance, infectious disease prevention, global health professional education gap, etc. [30–32]. The research findings of ATUN R. are mainly related to the interaction between global health initiatives and national health systems, cancer control in low-income countries, measures to improve health systems in developing countries, and innovations in health financing [33–35]. The dialectical relationship between economic development and global health, global health diplomacy, and the strengthening of the global health system are the main concerns of MCKEE M. [36,37].
