Abstract
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.
