基于DEMATEL-ISM的虚拟学术社区知识交流影响因素研究

Research on Influencing Factors of Knowledge Exchange in Virtual Academic Community Based on DEMATEL-ISM

虚拟学术社区逐渐成为科研用户获取知识的渠道,对虚拟学术社区知识交流影响因素的分析有助于改善知识交流的效果,促进知识创新活动。通过文献调研,构建了知识发送方、知识交流行为、知识交流情景与知识接受方4个维度14个因素的虚拟学术社区知识交流影响因素指标体系;以专家打分为依据,运用DEMLATEL方法分析因素因果关系与关键程度,并绘制因素因果图;最后根据ISM方法对影响因素进行层次划分。结果表明,关键影响因素中:知识交流量、交互强度、知识交流意愿位于表层;知识差距位于中间层;接受者知识存量和接受者知识创新量位于次深层。

The virtual academic community has gradually become a channel for scientific users to acquire knowledge.The analysis of the influencing factors of knowledge exchange in virtual academic community helps to improve the effectiveness of knowledge exchange and promote knowledge innovation activities.Through literature research,this paper builds a virtual academic community knowledge exchange influencing factor index system with four factors:knowledge sender,knowledge exchange behavior,knowledge exchange scenario and knowledge recipient;based on the experts’scores,analyzes the causal relationship of factors and key degree by using the method of DEMATEL,and draws the causal diagram of factors;classifies the influencing factors according to ISM method.The results show that among the key influencing factors,the knowledge exchange,interaction intensity and willingness to exchange knowledge are at the surface;the knowledge gap is located in the middle layer;the recipient’s knowledge stock and the recipient’s knowledge innovation are located in the sub-deep layer.
