[目的/意义]知识经济时代,知识扩散的路径研究是掌握知识发展动向、把握新机遇的重要途径.摸清知识扩散的规律与机制,有助于准确预测知识扩散的未来动向,推动知识的共享与发展.[方法/过程]以CNKI和Web of Science两个数据源近五年的图情学科研究型文献为例,采用文献计量的分析方法,结合SATI分析软件,从知识扩散的广度、速度、强度三个指标,以及知识扩散的主题演化方面,比较分析我国图情学者在国际和国内平台的知识扩散特征差异.[结果/结论]国内和国外图情学科的知识扩散广度在逐渐增加,但国外的增速更加明显;国内图情学科的知识扩散速度明显高于国外;国内向本学科的知识渗透率最高,在50％以上,国外更多渗透于其他学科,且与环境科学的交叉融合在逐年加深.
Research on the Characteristics of Knowledge Diffusion in the Field of Library and Information at Home and Abroad
[Purpose/significance]In the era of knowledge economy,the path research of knowledge diffusion is an important way to grasp the trend of knowledge development and seize new opportunities.Understanding the laws and mechanisms of knowledge diffusion will help to accurately predict the future trend of knowledge diffusion and promote the sharing and development of knowledge.[Method/process]This study takes research literature of library and information science in the past five years from CNKI and Web of Science as an example,uses the method of bibliometric analysis,combines with the SATI analysis software,and compares and analyzes the differences in knowledge diffusion characteristics of Chinese library and information scholars on international and domestic platforms in terms of the breadth,speed and intensity of knowledge diffusion,as well as the subject evolution of knowledge diffusion.[Result/conclusion]The results found that the knowledge diffusion breadth of the subject of library and information is gradually increasing both at home and abroad,but the growth rate is more obvious abroad;The knowledge diffusion speed of the subject of library information in China is significantly higher than that in foreign countries;The penetration rate of knowledge into this discipline is the highest in China,which is more than 50％.Foreign countries are more penetrating into other disciplines,and the cross-integration with environmental science is deepening year by year.
