Where Is Sharing-Economy Research in the BRICS Located? A Bibliometric Map of Countries, Disciplines, and Knowledge Structure

This paper maps the geographic, disciplinary, and intellectual structure reported for sharingeconomy research on the BRICS countries. The question matters because broad claims about “emerging-market” scholarship can conceal substantial differences in national participation and disciplinary framing. We conduct a bounded secondary analysis of the Web of Science tables and figures reproduced in the supplied manuscript; we did not independently retrieve or deduplicate the underlying records. Three results are directly reportable: (1) China accounts for 254 records in the manuscript’s corresponding-author country table, compared with 26 for India, 25 for Brazil, 19 for Russia, and 10 for South Africa; (2) the most frequent indexed categories include Business and Management (76 records each), Environmental Sciences (69), and Green & Sustainable Science & Technology (60), with categories overlapping; and (3) the source reports 443 documents overall, while annual counts sum to 419, preventing a reliable year-by-year growth claim. These patterns indicate a China-centered, multi-field literature whose comparative and cross-national balance is limited. Future research should reconstruct and publish a deduplicated record-level dataset with a fixed search protocol and countryspecific validation.
