[目的/意义] 当前，科研社交网络成为科研工作者一种重要的非正式交流工具，国内外的科研社交网络工具达到数十种，其中的佼佼者如ResearchGate、academia.edu已拥有数千万注册用户。本文对中外科研社交网络的功能建设情况进行了分析，以期从中借鉴经验，为今后的建设提供指导。[方法/过程] 首先通过科研社交网络学术论文的可视化分析，在此基础上总结出学界对这一工具的四大研究热点。随后基于科研社交网络功能和分类，扩展出23种具体功能，对每一类型中外代表性科研社交网络在重点功能上的表现进行了分析，发现共性、探索差异。[结论/结果] 研究显示，当前科研社交网络的学术资源与专家信息已经较为丰富，社交功能多样，但科研管理工具发展不够充分，社会化标签与替代计量指标的应用有待继续扩展。

[Purpose/significance] At present, the scientific social network has become an important informal scientific communication tool for researchers. There are dozens of scientific and social networking tools at home and abroad. Among them, such as ResearchGate and academia.edu have tens of millions registered user. [Method/process] Firstly, this paper summarized the five research focuses of this tool on the basis of the visual analysis of scientific research social networking academic papers. Then, based on A. C. Bullinger and S. H.Hallerstede's research on social networking functions and classification, we analyzed the Chinese and foreign representative social networks’ function design to explore the features, weaknesses and differences. [Result/conclusion] The above analysis shows that the development of scientific research management tools is not enough, and the social tagging and altmetrics still need continued exploration.
