Firms’ embeddedness in knowledge networks has received much attention in literature. However, little is known about the structure of firms’ knowledge exchange with respect to different types of proximities. Based on survey data of 295 firms in 8 European regions, we show that firms’...

Little effort has been made to identify industries'€™ knowledge networks, and to what extent knowledge relations occur between actors in different industries. This paper presents a network study on the Dutch aviation and space industry. Both industries are often treated as similar and...

The importance of geographical proximity for interaction and knowledge sharing has been discussed extensively in economic geography in recent years. There is increasing consensus that it is just one out of many types of proximities that might be relevant. We argue that proximity may be a crucial...
