Abstract: 【Purpose/significance】By analyzing the interaction mode and network structure of online health community members, this
paper discusses their value co-creation behavior, and provides suggestions for the sustainable operation and management of the com?
munity.【Method/process】Taking Baidu's "Depression Bar"as the research object, a mixed qualitative and quantitative research
method is adopted. First, the content analysis method is used to encode the crawled data, and then social network analysis is used to
explore the network structure characteristics and key users of each value network.【Result/conclusion】The results show that in the on? line health community, members create collective value in a unique way, and the three types of value generated coexist with each
other, among which the overall network and social value network have the highest correlation, knowledge value network and cultural
value network The value network has the lowest correlation; the connections between community members are not dense, and there is no core-periphery structure; most of the key user roles in the network overlap; According to the research results of this paper, three tar? geted suggestions are put forward.【Innovation/limitation】For the first time, explore the value co-creation behavior of online health community from the overall network structure of online community and the interaction between members. However, there are still some deficiencies in data selection, collection and application of research methods, which need to be improved in the future.
