摘要
我国的电力市场深化改革正处于关键阶段。目前国内外积累了大量研究成果但缺乏系统性梳理,同时新兴研究主题不断涌现,使得动态追踪热点成为难题。知识图谱能从海量文献数据中提取出结构化的知识谱系,其可视化图形又可呈现该领域演进历程与网络结构,因此能为电力市场研究的演进轨迹及热点追踪提供新的途径。该文基于知识图谱分析近十年国内1495篇、国外5106篇电力市场相关文献,通过构建市场领域代表性的研究数据集,快速提炼国内外研究轨迹与学术热点,合成时间线、关键词网络并将其可视化,探索近十年国内外电力市场研究的演进路径;对近五年电力市场领域的核心前沿进行分析研究,以突现性和中介中心性衡量图谱的关键点,全方面、多维度地追踪电力市场的研究热点。该文的研究成果能够深刻把握电力市场的热点与动向,为学者提供一种高效、快速应用的文献分析方法,具有广泛的应用前景。
The deepening reform of electricity market is at a critical stage in China.At present,a large amount of research has been accumulated at home and abroad,the corresponding systematic analysis is necessary.At the same time,new research topics continue to emerge,making it difficult for tracking research frontier.The knowledge graph can be applied to extract a structured knowledge pedigree from massive literature data,and its visual graphics can show the evolution process and network structure of the field,so it can provide a new way for the evolution trajectory and hot spots tracking of power market research.Based on the knowledge map analysis of 1495 domestic and 5106 foreign electricity market-related literature in the past ten years,this paper refined domestic and foreign research trajectories and academic hot spots by constructing representative research data sets in the market field,and synthesized timelines and co-word network maps with visualization.The evolutionary path of domestic and foreign power market research in the past ten years has been explored.The core frontiers of the power market in the past five years are analyzed,the key points of the map with emergence and intermediary centrality are measured,and the research of the power market in all aspects and multiple dimensions was tracked.The proposed approach of knowledge graph provides scholars with an efficient and fast-applied literature analysis method,which has broad application prospects.
