摘要:

【目的/意义】当前关于在线健康社区知识交流的系统研究仍存在不足,本文在延续前人研究的基础上,将
知识特征纳入知识交流效率的评价指标体系中,以准确测度在线健康社区的知识交流效率。【方法/过程】以丁香园
论坛的四个版块为例,将反映知识特征的知识密度和知识粘性纳入知识交流效率评价指标体系中,采用SBM模型
测度知识交流效率,并使用Tobit模型分析影响知识交流效率的因素。【结果/结论】丁香园论坛四个版块中呼吸胸
外的知识交流效率最高,肿瘤医学最低,四个版块整体的知识交流效率较低,且主要体现在纯技术效率不足;此外,
用户因素和社区因素均对知识交流效率有显著影响;最后从运营管理角度为在线健康社区知识交流效率提升提出
对策建议。【创新/局限】在构建评价指标体系过程中考虑知识特征对知识交流效率的影响,丰富了在线健康社区知
识交流效率研究的理论体系。

Abstract:

【Purpose/significance】At present, there are still some deficiencies in the research on the knowledge exchange of online
health community. Based on the previous research, this paper puts the knowledge features into the evaluation index system of knowl⁃
edge exchange efficiency, so as to accurately measure the efficiency of knowledge exchange in online health community.【Method/pro⁃
cess】Taking four boards of dingxiangyuan forum as an example, the knowledge density and knowledge stickiness reflecting knowledge
features are included in the evaluation index system of knowledge exchange efficiency. SBM model is used to measure the efficiency of
knowledge exchange, and Tobit model is used to analyze the factors affecting the efficiency of knowledge exchange.【Result/conclu⁃
sion】In the four boards of dingxiangyuan online health community forum, the efficiency of knowledge exchange outside respiratory
chest is the highest, and that of cancer medicine is the lowest. The overall efficiency of knowledge exchange in the four boards is low,
which is mainly reflected in the lack of pure technical efficiency. Pure technical efficiency is the key factor affecting the efficiency of
knowledge exchange. In addition, user factors and community factors have a significant impact on the efficiency of knowledge ex⁃
change From the perspective of operation management, this paper puts forward countermeasures and suggestions for improving the effi⁃
ciency of knowledge exchange in online health community.【Innovation/limitation】In the process of constructing the evaluation index
system, the influence of knowledge features on the efficiency of knowledge exchange is considered, which enriches the theoretical sys⁃
tem of the research on the efficiency of knowledge exchange in online health community.
