Scientist entrepreneurship across scientific fields

Knowledge generated in universities can serve as an important base for the commercialization of innovation. One mechanism for commercialization is the creation of a new company by a scientist. We shed light on this process by examining the role of scientist characteristics, access to resources and key university conditions in driving the likelihood of a scientist to start a company. Our sample comprises 1,899 university scientists across six different scientific fields. We make a methodological contribution by using self-reported data from the scientists themselves, whereas most previous research relied on university or public data. Our consideration of six scientific fields is a substantive contribution and reveals that scientist startups are heterogeneous in nature. Our findings are largely consistent with extant research on the role of individual and university variables in scientist entrepreneurship; in addition, we uncover the novel finding that the type of research field is also a key driver of scientist startup activity.
