Abstract: IT outsourcing is a knowledge-intensive business activity that requires effective knowledge sharing. However, there are some obstacles in knowledge sharing between the client and the service provider in IT outsourcing. On the basis of the existing research about knowledge sharing in IT outsourcing, we present the factors that influence knowledge-sharing behavior, and establish an evolutionary game model of knowledge-sharing behavior in IT outsourcing. We analyze the model in four situations to discuss evolutionary stable strategies by solving replicator dynamics equation and Jacobian matrix. Then we address the effects of the factors on evolutionary stable strategies, and identify some key factors by simulation with the use of Matlab(Version 7.6). The findings of this study show that, knowledge-sharing behavior in IT outsourcing is influenced by some key factors, including the amount of knowledge that can be shared, the degree of the complementarity of knowledge, trust between the client and the provider, the capacity of knowledge absorption and transformation, the cost and risk of knowledge sharing, and the incentive mechanism on knowledge sharing. Finally, some managerial implications are provided for IT outsourcing industry.

Key words: knowledge management, knowledge sharing, evolutionary game, IT outsourcing

摘要： 针对IT外包知识共享障碍的问题,在已有IT外包知识共享研究的基础上,依据演化博弈论建立了IT外包知识共享行为的演化博弈模型,通过求解复制动态方程与演化稳定策略,分析了影响IT外包知识共享行为的因素,并利用Matlab 7.6软件进行仿真。研究结果表明,知识可共享量、知识互补程度、信任、知识吸收转化能力、知识共享成本和风险以及激励机制等是影响IT外包知识共享行为的关键因素。最后提出相应的对策与建议。
