Abstract: It is important to learn the spatial features of the health care message producers and followers in the Internet world. We chose Sina microblog as the research object, which is very prominent for its Internet information flow, and selected the Pearl River Delta urban agglomeration as the sample source. On the basis of retrieval and content analysis, we separated the samples into two classes: producers and followers. We used social network analysis, spatial autocorrelation, and stepwise linear regression to learn the social network features of the producers and the spatial distribution features and influence factors of the followers. The results showed that: Firstly, the producers could build a local social network via the Internet. Differences were significant between groups but not between regions. Secondly, communication facilities and local medical level were the major factors for the spatial differentiation of the health care microblog followers. Finally, the spatial distribution of the followers was still limited by geographical factors.

Key words: health care microblog, message producer, message follower, spatial feature, the Pearl River Delta
