中文摘要：

以Web of Science中1990～2015年收录的知识共享研究文献为数据源，运用文献计量方法和指标以及社会网络分析技术，从科学产出与影响力、学科领域、作者分布、主题及热点领域等方面进行测度。研究产出明显增长，主要集中在美英等国，美国是最主要科学生产者；美国影响力最强，中国大陆较低；研究较广泛，呈现显著的多学科性和学科融合特征；合作程度较高，尚未形成稳定的高产作者群；社会资本、社会网络、社交媒体、气候变化等主题应给以关注。

英文摘要：

Selecting the literature on the knowledge sharing research in the Web of Science database during 1990 -2015 as data source, and combining the bibliometric methods and indexes with social network analysis techniques, the article makes an measurement in five aspects： scientific output, scientific influence, subject areas, author distribution and research topics and hot spots. The scientific research output of knowledge sharing has remarkably increased and mainly concentrates in the developed capitalist countries such as USA and England. USA is the primary scientific literature producer. The scientific influence of USA is the strongest, but Mainland China exhibits fairly poor scientific influence. Knowledge sharing is investigated more widely and shows the significant characteristics of multidisciplinary and subject integration. The level of overall cooperation is relatively high, and has not yet formed a stable and high-yield author group. These themes such as social capital, social network, social media, climate change and other topics should be given attention to.
