I am performing a bibliometric analysis of 2200 papers ranging from the year 1741 to 2020 and I wish to separate the network analyses (of collaboration between authors and between institutions) by a few stages from productivity. So far, I am only familiar with the industrial life cycle analysis approach, but it does not seem so relevant to assess productivity from the publication of scientific articles. In this sense, I would like to ask you: What is the best way to separate by a few stages the scientific productivity (ranges of years for subsequent analyses) in a field of knowledge?
Thank you very much
