Abstract: 【Purpose/significance】In order to evaluate the influence of scientific research team more fairly, aiming at the problem of
neglecting citation distribution bias in the current scientific research team evaluation, this paper proposes a new evaluation index of in?
fluence of scientific research team, cited Balance Index (Cb index for short).【Method/process】Taking 10 scientific research teams in
the field of information science as an example, first, the paper found out 10 scientific research team members by Social Network Analy? sis (SNA); then downloaded the cited information of the scientific research team in the Chinese Citation Database; finally, using the re? vised Theil index to measure the average citation frequency of the scientific research team. Equilibrium, calculated the Cb value of sci? entific research team.【Result/conclusion】The empirical study shows that the new Cb index can comprehensively consider the bal? ance of the number of papers published, the frequency of citations and the number of citations, and evaluate the influence of scientific research team more comprehensively and fairly.【Innovation/limitation】The cited balanced Cb index provides a new method for evalu? ating the influence of scientific research teams, but it still needs to be further tested in the future.
