This paper contributes to the literature on entrepreneurship and economic geography by identifying factors that determine the attractiveness of a site in a metropolitan area, as the basis for the emergence of high-tech firms’ spatial concentration. The econometric model provides distinct advantages over the largely descriptive approaches that have been dominant in the point pattern analysis literature for clusters. We focus on the role of two types of knowledge spillovers on a firm’s location choices: (1) those that arise from collocating with other companies from the same industry, and (2) universities’ knowledge spillovers. A model is estimated using data on firm births in high and medium–high-technology manufacturing industries, during 2000–2016 in Madrid. Our results show that the main source through which firms benefit from knowledge spillovers is through proximity to firms in the same industry and not from universities.

本文通过确定决定大都市区某场所吸引力的因素，为高科技企业的空间集中度的出现奠定基础，从而为有关企业家精神和经济地理学的文献做出了贡献。计量经济学模型提供了明显优于群集的点模式分析文献中占主导地位的描述性方法的明显优势。我们将重点放在两种知识溢出在公司的地点选择上的作用：（1）与同行业的其他公司合作产生的知识溢出；（2）大学的知识溢出。使用马德里在2000年至2016年期间高，中，高技术制造业的公司出生数据估计了一个模型。
