"In their analysis of the empirical evidence in support of the Knowledge Spillover Theory of Entrepreneurship, Audretsch and Link conclude that there is no singular source of knowledge driving entrepreneurship, but a plethora of knowledge sources, each associated with different dimensions of entrepreneurial activity. The intellectual breakthrough in this book is not that knowledge matters or that it especially matters for entrepreneurship. Rather, Audretsch and Link show that knowledge, and especially entrepreneurial knowledge, is not a homogeneous phenomenon. There are multiple sources of knowledge that act on entrepreneurial performance in a myriad of ways."-- |
