摘　　要：运用微观扩散模型和计算机仿真相结合的方法分析网络外部性市场中的创新扩散,研究表明网络效应特征、采纳个体自身偏好异质性特征是决定网络外部性市场创新扩散动力学机制的重要因素。网络效应特征对创新扩散正向影响的大小取决于网络效应的类型(直接或间接网络效应)和强弱。采纳个体偏好异质性特征对创新扩散的影响并不确定,直接网络效应下偏好异质性对创新扩散程度的影响呈现先增后减的趋势;间接网络效应下偏好异质性对创新扩散程度的影响则存在"临界点"现象,且上述因素对网络外部性市场中创新扩散的影响还会由于采纳个体之间交互作用所形成的复杂社会网络结构差异而呈现不同模式。The paper uses the micro diffusion model and computer simulation methods to study the innovation of diffusion in the market with network externalities. The research results show that network effects and heterogeneity of adopters＇preference are two significant factors which have a deep impact on the dynamics of innovation diffusion in the market with network externalities. The positive influence of network effects depends both on the type and strength of network effects （ direct or indirect）. However, the effects of adopters＂ heterogeneity on innovation diffusion are uncertain. Under the situation of direct network effects, the effects of adopters＂ heterogeneity on the innovation diffusion are positive early and then negative. Under the situation of indirect network effects, the effects of adopters＂ heterogeneity on the innovation diffusion exhibit the phenomenon of ＂critical mass＂. Furthermore, the influence of those factors above on the innovation of diffusion in the market with network externalities would exhibit different patterns due to the different structures of complex social network formed by the interactions of innovation adopters.
