RESEARCH UNIVERSITIES AND REGIONAL HIGH‐TECH FIRM START‐UP AND EXIT
利用1999-2005年德克萨斯州数据，分析研究型大学对高科技企业创立和退出率的影响，发现大学研发和邻近性促进企业创立，但不降低退出风险。
If localized knowledge spillovers are present in the university setting, higher rates of both start‐up and/or survival would be observed in areas that are geographically proximate to the university. Using a detailed industry data set for Texas for 1999:3–2005:2, we analyze start‐up and exit rates for high‐tech firms. Based on a Poisson quasi‐maximum likelihood estimation, we find evidence that the level of R&D and proximity of a research institution positively affects the likelihood of technology start‐ups. However, using both the Cox proportional hazards model and Kaplan–Meier approach, our results suggest that geographic proximity to knowledge centers does not reduce hazard rates.
