摘要
针对目前学术虚拟社区知识交流效率研究均未剔除环境因素影响的问题,本文在分析环境因素对学术虚拟社区知识交流效率影响的基础上,剔除外生因素对学术虚拟社区知识交流效率的影响,为进一步客观评价学术虚拟社区的知识交流效率提供参考。本研究采用三阶段DEA(data envelopment analysis,DEA)模型,以“小木虫”论坛的有机交流、第一性原理、微米和纳米、金融投资4个版块为例,对比分析剔除外生因素前后学术虚拟社区知识交流效率的变化。研究结果发现,剔除外生因素的影响后,学术虚拟社区的知识交流效率有所提升,但仍未实现决策单元(decision making unit,DMU)有效;第一阶段和第三阶段的测算结果均显示第一性原理版块的知识交流效率最高;在环境变量对学术虚拟社区知识交流效率的影响中,散金数、用户总发帖、社区管理者参与度以及社区成员质量对学术虚拟社区知识交流效率有正向影响作用,而用户加入社区时长与用户在线时长等因素对社区知识交流效率有负向影响。
The purpose of this paper is to analyze the influence of environmental factors on the efficiency of knowledge exchange in academic virtual communities based on an analysis of the impact of exogenous factors.It also provides a reference for further objective evaluation of the knowledge exchange efficiency of academic virtual communities.The method is based on a three-stage Data Envelopment Analysis(DEA)model and uses the organic communication,first principles,micron and nano,and financial investment sections of the Little Woodworm Forum as examples and reports the changes in the efficiency of community knowledge exchange.The study shows that after excluding the influence of exogenous factors,the knowledge exchange efficiency of the academic virtual community improved;however,the decision making unit(DMU)was still not effective.The results for the first and third stage show that the knowledge exchange efficiency of the first-principles section was the highest.The influence of environmental variables on the knowledge exchange efficiency of academic virtual communities such as the number of loose funds,the total number of users’posts,the participation of community managers,and the quality of community members had a positive effect on the knowledge exchange efficiency of such communities.Factors such as the number of online users had a negative impact on the efficiency of community knowledge exchange.
