Abstract

This paper investigates how far in space university knowledge goes to breed the creation of knowledge-intensive firms (KIFs), depending on the nature (either codified or tacit) and quality of this knowledge. We consider the impact of knowledge codified in academic patents and scientific publications and tacit knowledge embodied in university graduates on KIF creation in Italian provinces in 2010, while distinguishing between local university knowledge created by universities located in the same province and external university knowledge created by universities located outside the province. Our econometric estimates indicate that the positive effects of scientific publications and university graduates are confined within the boundaries of the province in which universities are located. Conversely, the creation of new KIFs in a focal province is positively affected by both local and external university knowledge codified in academic patents, even though the positive effect of this external knowledge rapidly diminishes with geographic distance. Furthermore, the above effects are confined to high-quality universities; low-quality universities have little effect on KIF creation. Copyright Springer Science+Business Media New York 2014
