Abstract:

【Purpose/significance】In view of the insufficient research in microblog health information, this paper explores the informa⁃

tion interaction in microblog health care, and promotes the development of microblog health care efficiently and smoothly.【Method/pro⁃

cess】Using the V list bloggers data of microblog health care as a sample, the paper makes basic indicators analysis, centrality analysis,

cohesive subgroup analysis, core-periphery analysis and structural hole analysis by UCINET based on SNA.【Result/conclusion】Mi⁃

croblog health information interaction runs smoothly with a certain small world effect. But the degree of interaction is insufficient. The

core bloggers show a concentrative trend, but the network remains loose. The phenomenon of small groups exists, but the closed small

groups is still not prominent. The network is in a good state of openness.【Innovation/limitation】This paper systematically explores the

microblog health information interaction in the perspective of SNA; marketing links between microblog bloggers may lead to results

distortion.
