This paper seeks to explain the variable outcomes from university entrepreneurial ecosystems by observing their structural and spatial configurations in relation to spinoff company development. Four UK university entrepreneurial ecosystems are examined with data collected through interviews with the core actors of university entrepreneurial ecosystems: technology transfer officers, academic founders, external entrepreneurs, investors, and business incubators. It is found that university entrepreneurial ecosystem outcomes are dependent on the processes of connectedness and filtration, underpinned by geography. The effectiveness of these processes is dependent on university entrepreneurial ecosystem calibration, leading to different outcomes in terms of spinoff company formation and survival across the spectrum of universities. Successful university entrepreneurial ecosystems are characterised by strong connectedness and effective filtration, having a strong local and interregional character.

本文试图通过观察与创业公司发展相关的结构和空间配置，来解释大学创业生态系统的可变结果。通过采访大学创业生态系统的核心参与者：技术转让官，学术创始人，外部企业家，投资者和企业孵化器，对英国的四个大学创业生态系统进行了调查。研究发现，大学创业生态系统的成果取决于地理学支持的联系和过滤过程。这些过程的有效性取决于大学企业生态系统的校准，从而导致在衍生公司的组建和整个大学生存方面的不同结果。
