Network Effects Revisited: The Role of Strong Ties in Technology Selection
超越传统将技术用户视为同质个体的网络效应理论，引入社会网络中的强关系概念，通过无线通信行业数据检验了强关系网络效应对技术选择的影响。
This paper extends the theory of network effects by moving beyond the traditional treatment of the installed base of a technology as composed of “N” identical users, each having the same effect on the rest of the users. Borrowing from social network theory, I propose the concept of strong-ties network effects as a key determinant of technology adoption in cases where several technologies compete. A discrete-choice model was tested in the wireless telecommunications industry.
