“…Generally speaking, availability of universities, incubator or technology parks, access to venture capital funds, and knowledge of potential investors or partners, are decisive factors for creating spin-offs. More specifically, the presence of venture capitalists, the capacity to generate internal funds or the capacity to work in high-tech sectors (Rodríguez-Gulías et al 2017), the availability, size and experience of TTOs (Fritsch and Aamoucke, 2013;Link and Scott 2005;O'Shea et al 2005;Powers and McDougall 2005), as well as the development of R&D incubators that promote knowledge spillovers (Acs et al, 2013;Leyden and Link, 2013), can crucially support spin-off creation and growth. The availability of internal funding has been a key determinant in the spin-off growth due to the fact that their main assets are intangible, and they could not be used as a guarantee for banks (Rodríguez-Gulías et al 2017).…”
