University-industry interaction in Santa Catarina: evolutionary phases, forms of interaction, benefits, and barriers

University-industry interaction (U-I) acquires relevance to countries to the extent that they identify how scientific knowledge produced within universities enhances technological development in firms and facilitates innovations. Universities are invigorated by the possibility of new scientific investigations that these relationships provide. The objective of this article is to analyze the establishment and development of U-I interactions in Santa Catarina, Brazil, of four universities through evolutionary phases, forms of interaction, benefits, and barriers. A total of 38 in-depth interviews were conducted during the data collection stage. To support the analysis and presentation of results, the qualitative data analysis software Atlas/ti, version 7.1.3 was used. The results pointed to non-linearity in the evolution of U-I interaction and demonstrate that most of the relationships between universities and firms are concentrated in traditional and services channels. Moreover, their interaction intensity is evident in the short term with the flow of knowledge being directed from universities to firms. With regard to benefits and barriers, the research results expand on the avenues outlined in the literature, which reflects some characteristics of this interaction type in Brazil, whose relationships are still new and do not yet have a solid trajectory.
