数字经济的研究演变和热点分析——基于文献计量方法

Research Evolution and Hot-spot Analysis of the Digital Economy:Based on Bibliometrics Approach

在数字化发展时代,经济学家对于数字经济的研究越来越多,把握数字经济的发展方向和研究热点的变化就显得尤为重要。将数学和统计学的方法相结合,采用文献计量的方法对数字经济研究的发展进行梳理与剖析,统计数字经济文献的整体增长趋势、研究领域、科研机构和核心作者,并构造共被引网络进行引文聚类,同时绘制关键词时区图,分析数字经济研究的前沿热点及其动态演化。结果显示:数字经济研究从一开始对“数字经济”概念本身单一的研究,逐渐发展到后面的多学科多领域的交叉研究,特别是对互联网经济、大数据与绿色经济、低碳经济的研究慢慢成为数字经济研究的主流。

In the digital development age,economists have done more and more research on digital economy.It is particularly important to grasp the development direction of digital economy and the changes in research hot-spot.Combing mathematical and statistical methods,bibliometrics has been applied to sort out and analyze the development of digital economy research,track the overall growth trend of digital economy literature,research field,scientific research institutions,and core authors,and construct a co-citation network for citation clustering.At the same time,keyword time zone map has been drawn to analyze the frontier hot-spot of digital economy research and its dynamic evolution.The result shows that from the initial single study of the concept of the"digital economy"itself,it has gradually developed to the later multi-disciplinary and multi-field research.In particular,the research on Internet economy,big data and green economy,and low-carbon economy has gradually become the mainstream of digital economy research.
