摘要
对基于模仿的技术扩散重要研究进行了回顾。以信息不完全为出发点的理论研究主要包括传染病模型和贝叶斯学习模型等;以企业动机为出发点的研究主要包括两阶段的计量模型、门槛模型等。这些研究表明,信息传播所依赖的社会关系网络、技术引进者关于新技术信息的完整性以及企业规模的大小是决定技术扩散的影响因素。此外,关于技术扩散空间过程的一些重要研究,其本质就是传染病模型与门槛模型的空间版本。
The paper reviewed the research about technology diffusion based on imitation, The first kind of the theories is based on the imperfection information, including Epidemic models and Bayesian learning models. The second is based on corporation＇s Incentive, including two-stage econometric models and Threshold Models. These researches indicated that social network, the information about innovation and the corporation＇s scale are the crucial factors for the diffusion process of technology. In addition, the spatial models about the technology diffusion are similar to the Epidemic models and Threshold Models.
