[目的/意义] 基于ESI数据库中的研究前沿模块，结合专家研判对营养学领域的研究前沿进行遴选，并运用文献计量学方法分析主要国家在营养学前沿研究中竞的争力结构，揭示中国在全球营养学前沿中的贡献度和影响力。[方法/过程] 以ESI数据库中9256个研究前沿为基础，通过文献检索、专家遴选等方法筛选出营养学领域研究前沿129个，经过系统性分类形成6个研究方向，对各研究方向的核心论文、施引文献进行分析，计算各国核心论文份额、施引论文份额、核心论文被引频次份额，揭示世界主要国家在这些研究前沿中的活跃度、贡献度和影响力。[结果/结论] 对营养学研究前沿数据的分析结果显示：美国在营养学研究处于领先地位；中国营养学研究成果显著，但与美国相比还存在一定差距，且整体发展不均衡，但是具有一定的发展潜力。本研究提示情报分析人员与学科专业研究人员密切配合，运用科学计量学方法能够了解各学科领域研究产出的现状和发现研究热点的发展趋势，揭示国家之间的竞争力态势，促进各学科领域的可持续发展

[Purpose/significance] Based on the research fronts module in ESI database and the research fronts in the field of nutrition selected by domain expert, this paper uses the bibliometrics methods analyzes the competitive advantages of key countries and  reveals the contribution and influence of China in the research fronts of global nutrition. [Method/process] By the methods of information retrieval and expert screening, 129 research fronts in the field of nutrition were identified from 9256 ESI research fronts, and these research fronts were divided into 6 research directions. Then, by analyzing the core papers and the citing papers of each group, each country’s share of core papers, share of cited papers and share of cited frequency of core papers were calculated. Finally, based on the above works, the key country’s activity, contribution and impact in the nutrition field were identified. [Result/conclusion] Further analysis of research fronts shows that USA is in a leading position in the field of nutrition. Chinese performance is also significant, but there is still a gap with the United States. Meanwhile, the analysis reveals that there is great potential for China, although the current research development of nutrition in China is not balanced. This Study suggests that the collaborated work between information analysts and domain experts enables a better use of scientometrics. Through the analytical results, we are able to better understand the research status, identify the development trend, demonstrate the competitive advantages of key countries, and accelerate the sustainable development of the studied discipline.
