Regional metrics for entrepreneurial ecosystems in Europe

This dataset measures the entrepreneurial ecosystems and entrepreneurship outputs of 273 NUTS-2 regions in Europe. The entrepreneurial ecosystem model of Stam and Van de Ven (2021) is used to operationalize the entrepreneurial ecosystem concept. The ten elements in the model are measured by statistical indicators on the regional level. The dataset contains metrics for each entrepreneurial ecosystem element as well as an index measuring the overall quality of the entrepreneurial ecosystem. The data collection and choices regarding indicators are extensively described in Leendertse et al. (2021). The output of entrepreneurial ecosystems is productive entrepreneurship. The dataset contains two measures of productive entrepreneurship: innovative startups (less than 5 years old) and unicorn firms (young private firms with a valuation of more than $1 billion).本数据集针对欧洲273个NUTS-2级区域的创业生态系统与创业产出开展量化测度。研究采用Stam与Van de Ven（2021）提出的创业生态系统模型对该概念进行操作化定义，模型包含的10个核心维度均通过区域层面的统计指标完成量化。本数据集不仅涵盖各创业生态系统维度的具体测度指标，还包含用于衡量创业生态系统整体质量的综合指数。有关数据采集流程与指标选取的详细说明，可参见Leendertse等人（2021）的研究成果。创业生态系统的产出为生产型创业活动，本数据集包含两项生产型创业活动的测度指标：一是成立时长不足5年的创新型初创企业，二是独角兽企业（即估值超过10亿美元的年轻私有企业）。
