基于SFA方法的虚拟学术社区知识交流效率研究

Research on the Efficiency of Knowledge Exchange in Virtual Academic Community Based on SFA Method

【目的/意义】采用参数模型研究虚拟学术社区知识交流的技术效率,为正确评价虚拟学术社区在知识交流中的地位及促进知识的转化提供依据。【方法/过程】在已有研究中,大多是采用非参数形式进行效率测度,本文采用参数形式SFA方法测算"经管之家"经济学论坛三区的知识交流效率,并运用非参数核估计对知识交流技术效率进行动态演化。【结果/结论】"经管之家"经济学论坛三区6个版块整体知识交流效率较高,但呈现出效率递减趋势;知识交流效率较高的版块发展态势不如知识交流效率较低的版块;最后从论坛管理者角度提出改善知识交流现状和促进知识创新的意见。

【Purpose/significance】A parametric model is applied to study the technical efficiency of knowledge exchange in virtual academic community, so as to provide a basis for correctly evaluating the status of virtual academic community in knowledge exchange and promoting knowledge transformation.【Method/process】In the previous studies, most of them use non parametric forms to measure the efficiency.In this paper, we use parametric SFA method to measure the efficiency of knowledge exchange in the three area of economics forum, and use non parametric kernel estimation to dynamically change the efficiency of knowledge exchange technology.【Result/conclusion】The overall knowledge exchange rate of the 6 sections of the economic forum of the three area of the economic forum is high, but the trend of efficiency decreases; the development situation of high efficiency of knowledge exchange is not as good as the lower efficiency of knowledge exchange; finally, from the point of view of the forum manager, the opinions on improving the current situation of knowledge exchange and promoting knowledge innovation are put forward.
