This paper explores incubator facilitation of technology transfer for their New Technology-Based Firms (NTBFs). Empirical evidence gathered from six interviews with incubator managers, together with a survey of 131 NTBFs in incubators in Sweden, in 2005, and the findings made in a survey of 273 NTBFs situated inside-and-outside Science Parks in 1999, are used for the exploration. It is suggested that incubators do facilitate technology transfer for their NTBFs. It is further suggested that the development towards increased ability to facilitate technology transfer will continue as a results of the efforts made on the incubator and systemic level.
