[目的/意義]探討虛擬社區環境因素如何影響用戶知識共享行為,為虛擬社區的良性發展提供借鑒。[方法/過程]首先對虛擬社區環境及用戶知識共享行為的概念和特性作出了界定,然后分別從微觀層面、中觀層面、宏觀層面對虛擬社區環境因素的構成進行了解析,進而探討了各環境因素對社區用戶知識共享行為的作用機制,在此基礎上提出了各環境因素對虛擬社區用戶知識共享行為的協同作用機制。[結果/結論]構建虛擬社區環境因素作用機制模型具有較高的價值意義和可行性。[局限]作用機制模型的實際作用需要更多的實證研究和數據支撐來檢驗。

[Purpose/significance] This paper aims to explore how virtual community environmental factors affect user knowledge sharing and provide a reference for the healthy development of virtual community.[Method/process] Firstly,this paper defines the concept and characteristics of virtual community environment and user knowledge sharing behavior.Then,the paper analyzes the compositions of the virtual community environment from the micro level,the meso level and the macro level respectively.And then,the paper explores the mechanism of environmental factors on knowledge sharing behavior of community users.On this basis,the paper puts forward the synergistic mechanism of environmental factors on the knowledge sharing behavior of virtual community users.[Result/conclusion] It is of great value and feasibility to construct the mechanism model of virtual community environmental factors.[Limitations] The practical role of the mechanism model requires more empirical research and data support.
