本研究以知识生命周期和无形学院作为理论支撑，以科学知识图谱法和社会网络分析法为技术手段，选择CNKI中国知网学术期刊数据库自1993年至2018年25年间中国新闻传播学界有关健康传播研究的期刊学术论文，筛选梳理有效学术论文317篇，从中窥视中国健康传播研究的演进历程、运行机制和社会网络。 研究发现，当前中国大陆健康传播研究存在显著的实践导向特征，学界的研究主题和研究重点伴随着社会热点和社会动态的变化而变化。从时间维度上看，中国大陆健康传播研究总体上符合知识生命周期的达尔文主义，其重点研究议题上存在比较明显的研究阶段和历时脉络。不同议题存在明显的“用进废退”的特征，2014年新媒体的兴盛成为中国大陆健康传播研究议题的重要分水岭。 从空间维度上看，目前中国大陆健康传播研究尚未形成稳定的合作网络，少许的固定合作网络一般是基于地缘或业缘关系的合作，基于研究者合作关系的健康传播无形学院还有待发展。当前中国健康传播存在一定的马太效应，一些高发文量的学者已成为中国大陆健康传播的重要人物，但其优势垄断地位并不明显。从研究机构上看，中国传媒大学、南昌大学、中国人民大学等数所211高校成为中国大陆健康传播研究的领军科研机构，科研机构之间的合作并不频繁。目前健康传播研究的科研机构集中度不高，尚未出现占据垄断地位的优势科研机构。 从社会网络分析来看，1993-2018年这25年间，中国大陆健康传播研究领域的文献互相引用的网络愈发复杂，但整体上文章相互引用率不高。现阶段中国大陆健康传播研究的引文网络密度较小，传承效应较差。健康传播的引文网络平均距离较小，年度变化幅度不大，知识更新速度较快，但研究内容的凝聚力较差。目前健康传播引文网络中凝聚子群较少，尚未构成完整的研究流派。

This research took knowledge life cycle and intangible college as the theoretical basis, the scientific knowledge map method and the social network analysis method as the uncle technology segment, and selects the CNKI China Knowledge Network Academic Journal Database from the year of 1993 to 2018. After disseminating research journals and academic papers, the research sort out 317 effective academic papers and peep into the evolutionary history, operational mechanisms, and social networks of Chinese health communication research. The study found that the current research on health communication in Mainland China has significant practice-oriented features, and academic research topics and research priorities have changed along with changes in social hotspots and social dynamics. From the perspective of time, China's health communication research generally conforms to Darwinism of the knowledge life cycle. There are relatively obvious research phases and historical contexts on key research topics. Different topics have obvious characteristics of "use of waste", and the rise of new media in 2014 has become an important watershed for research on health communication in mainland China. From the perspective of space, at present, the research on health communication in Mainland China has not yet formed a stable cooperation network. A few fixed cooperation networks generally cooperate with each other based on geographical or occupational relationships. Intangible colleges of health communication based on researcher cooperation relationship have yet to be developed. Some high-achieving scholars have become leaders in health communication in mainland China. There is a certain Matthew effect in the current health communication in China, but the dominant monopoly status of the leader is not obvious. From the perspective of research institutions, 211 colleges and universities such as Communication University of China, Nanchang University, and Renmin University of China have become the leading research institutes for health communication research in mainland China. Cooperation between scientific research institutions is not frequent. At present, the concentration of research institutions in health communication research is not high, and there are no dominant research institutions that occupy monopoly positions. From the perspective of social network analysis, in the 25 years from 1993 to 2018, the networks of reference to each other in the research field of health communication in mainland China have become more and more complex. However, the overall article citation rate is not high. At this stage, the citation of health communication in mainland China The network network density is low and the inheritance effect is small. The average distance of health communication citation networks is small and the annual variation is small. However, the cohesion of the research content is poor, and the knowledge update rate is faster. At present, there are few cohesive subgroups in health communication citation networks, which have not yet constituted a complete research school.
