英文摘要：
Thanks to the recent availability of comprehensive and detailed online databases of startup companies, it has become possible to more directly investigate startup ecosystems i.e. startup populations in specific regions. In this paper, we analyze the emergence of 20+ such ecosystems in Europe and the USA, with a specific focus on their sectoral diversity. Analyzing the sectoral landscapes of these ecosystems using a new visualization tool indeed highlights marked differences in terms of diversity, which we characterize using metrics derived from ecological sciences. Numerical simulations suggest that the emerging diversity of startup ecosystems can be explained using a simple preferential attachment model based on sectoral funding.

中文摘要：
由于最近提供了全面详细的创业公司在线数据库，因此可以更直接地调查创业生态系统，即特定地区的创业人口。在本文中，我们分析了欧洲和美国20多个此类生态系统的出现，并特别关注其部门多样性。使用一种新的可视化工具分析这些生态系统的部门景观确实突出了多样性方面的显著差异，我们使用来自生态科学的指标来描述这种差异。数值模拟表明，新兴创业生态系统的多样性可以用基于部门资金的简单优先依附模型来解释。
