3.3 Research areas distribution of structural holes theory

Web of Science marks the “research areas” for each paper, which is equivalent to a particular
subject or discipline in the field. If it is an interdisciplinary research papers, all involved research
areas will be marked. According to the detailed classification of each paper in the citation network,
