Abstract: By comparing with previous work and building technology transfer model in information technology industry into the external enterprise contract approval model, the technology transfer model involving information technology professionals, a technology transfer center and an enterprise is constructed in a mathematic way. It is proved that in the external enterprise contract approval model, uncooperative equilibrium exists in information technology professional and enterprise. The core innovation of this paper is whether information technology professionals or enterprises will participate in technology transfer depending on marginal revenue of information technology professionals and the marginal investment cost of the technology transfer.
