摘要
[目的/意义]互联网医疗行业发展迅猛,探究当前医疗健康类网站的市场竞争态势,有助于更新人们对互联网时代下医疗行业的认识,同时为从业人员提供市场决策支持。[方法/过程]以站长之家医疗健康类网站综合排名前50位的网站为研究对象,借助微软必应(Bing)搜索引擎获取这些网站之间的URL共现频次,对共现矩阵进行社会网络分析,聚类分析和多维尺度分析等,来揭示它们的竞争关系和市场格局。[结果/结论]结果显示网站的中心性排名与站长之家排名显著相关,同时可将50家网站分为健康资讯和在线问诊类、网上药店类、医学工具类三大类,同一类团内各网站功能相似,市场竞争激烈。市场中影响力较大的为健康资讯和在线问诊类网站。分析结果与行业事实竞争格局大致相符,为URL共现分析用于竞争情报分析又提供了又一实证研究。
