中国互联网产业价值链研究的知识图谱分析——基于1999-2018年CNKI数据库核心文献数据

A Knowledge Graph Analysis of Studies on the Value Chain of China’s Internet Industry——Based on the Core Literature Data of CNKI from 1999 to 2018

互联网产业已经成为中国数字经济发展重要引擎。基于产业价值链视角,采用CiteSpace软件,对678篇相关核心期刊文献进行科学知识图谱分析,构建了互联网产业价值链关键词共现图谱、时区图谱、共被引聚类图谱、时间线图谱等。结果显示中国互联网产业价值链相关研究经历了萌芽期、发展期、沉寂期、进发期、繁荣期,研究热点和演化主题不断更新,互联网产业核心竞争力逐渐形成,亟须融入全球价值链中创新突破。

The Internet has grown into an important engine for China’s digital economy. Based on the perspective of industrial value chain, this paper conducts a knowledge graph visualization analysis of 678 related core journal literatures with the software CiteSpace so as to build keywords co-occurrence graph, time zone graph,co-citation cluster graph, and time line graph for Internet industry value chain. The findings indicate: the study on the value chain of China’s Internet industry has experienced periods of budding, developing,stagnation, booming and prosperity;research hotspots and evolutionary topics are constantly updated;the core competitiveness of Internet industry is gradually formed and urgently needs to be integrated into the global value chain to realize innovation and breakthrough.
