Abstract: The mechanism of the transmission of information by technological gatekeepers inside R&D groups needs to be reexamined under the utilization of internet technology. The Beijing R&D group of a pharmaceutical enterprise was taken as the case. SNA and interviews were made. Affected by the internet technologies, the proportion of technological gatekeepers is 6%, much lower than the well accepted proportion of 20%. The role of gatekeepers can be separated into internal communication stars and external communication stars. New framework on the mechanism of information transmission in R&D group is established.
