摘　　要：文章采用CITESPACE软件,围绕新能源研究主题,编辑检索式TS=("new energy"or"clean energy"or"renewable energy")对web of science数据库核心集进行数据挖掘,基于合作网络、贡献网络、基金等三个视角阐述文献数据信息。研究表明:(1)我国在新能源研究领域文献产量居全球首位,但中心度不高;(2)新能源研究主题呈"宽泛-具体"态势,未来新能源研究问题将进一步细化;(3)中国在有关新能源研究领域的基金支撑远高于美国等发达国家。CITESPACE software was used to conduct data mining on the web of science database by editing and retrieving TS=( "new energy" or "clean energy" or "renewable energy") around the research topic of new energy. Literature data information was elaborated from three perspectives including cooperative network, contribution network and fund support. The research shows that:(1)China’s literature output in the field of new energy research ranks first in the world, but its centrality is not high;(2) the theme of new energy research is "wide-specific", and the future research on new energy will be further refined.(3) China’s fund support in the field of new energy research is much higher than that of developed countries such as the United States.
