摘要：本文探讨在信息系统外包或购置商品软件开发方式下，IS外部提供方与IS需求方的个体之间，信息系统双向知识转移的影响因素。首先在知识转移、信息系统理论的文献基础上，形成一个理论模型，假定信息系统双向知识转移受知识相关因素（共识）、交流相关因素（双向信任、双方的交流能力）的影响。然后采用无干扰实证研究方法，基于讨论信息系统知识的网络论坛，模拟实际情况，收集数据进行回归分析，论证了12项假设中的10项，证实了这两组影响因素与双向知识转移的关系。  

Abstract： The influence factors of Information Systems (IS) bidirectional knowledge transfer which between IS outside supplier and IS demander in the development mode of IS application outsourcing or pruchasing application software package are explored. Firstly, drawing from the knowledge transfer and IS literatures, a theoretical model is developed, the model presumes that IS bidirectional knowledge transfer is influenced by knowledge-related (shared understanding), communication-related (bidirectional trust, communication capabilities of both sides) factors.Then, a non-intervention empirical researchis adopted to simulate real situation, and data is collected based on an internet forum discussing IS knowledge for regression analysis. The analysis provides support for 10 of the 12 hypotheses and confirms two mediating relationships.
