中文摘要：

互联网医疗可以打破时空限制为人们提供医疗信息和服务，为了探究在线医疗社区在优化医疗资源配置方面的作用，本文以好大夫在线为例进行了实证分析。首先通过聚类分析划分各地区的医疗发展层次，然后分析了医疗信息资源在不同发展层次地区间的流动特征。研究发现医疗条件发达地区主要承担医疗服务提供者的角色，而医疗条件欠发达的省份则主要扮演医疗服务接受者的角色。所以在线医疗社区能够利用互联网促进优质医生资源和医疗信息服务跨地区流动，有利于改善我国医疗资源配置不均的情况。

Firstly, clustering analysis was used to evaluate their medical level. After that, this paper analyzed the flow of medical information resources among provinces with different medical level. It found that areas with developed medical facilities played the role as medical service providers.
