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.

摘要： 技术把门人在研发团队信息传递中的作用机制在互联网技术的影响下需要重新审视。对某制药企业北京研发团队进行案例研究，使用社会网络分析(SNA)并做人员访谈。分析结果表明，在互联网技术的影响下，技术把门人在研发团队中所占比例为6%，远低于以往研究公认的20%。技术把门人角色可分离为外部交流明星和内部交流明星。建立了研发团队信息传递机制新的概念框架。
