摘要

当新企业进入或离开其所在的城市街区时，企业的创新活动会发生什么变化？我们利用柏林的企业级面板数据，通过企业动态对知识外溢的作用进行了实证探索。结果表明，通过新企业的进入和涌入，周边地区企业活动的增加与现有企业的创新活动呈正相关。这一发现仅限于多样性外部性，它在很小的微观地理范围内发挥作用，在四分之一公里后就会消失。至于通过企业动态产生的专业化外部效应，我们找不到与在职者创新的联系。

Firm dynamics in urban neighbourhoods and innovation: A microgeographic analysis

What happens to firms’ innovation activities when new firms enter or leave their urban neighbourhood? We empirically explore the role of knowledge spillovers through firm dynamics using firm-level panel data from Berlin. The results indicate that an increase in firm activities in the neighbourhood through entries and influx positively relates to incumbents’ innovation activities. This finding is restricted to diversity externalities which work on a very small microgeographic scale, vanishing already after a quarter of a kilometre. For specialisation externalities through firm dynamics, we cannot find a link to innovation in incumbents.

期刊介绍： Urban Studies was first published in 1964 to provide an international forum of social and economic contributions to the fields of urban and regional planning. Since then, the Journal has expanded to encompass the increasing range of disciplines and approaches that have been brought to bear on urban and regional problems. Contents include original articles, notes and comments, and a comprehensive book review section. Regular contributions are drawn from the fields of economics, planning, political science, statistics, geography, sociology, population studies and public administration.
