New Publication on regional cooperation and innovation

coverMy paper, „An investigation of the relation between cooperation and the innovative success of German regions„, has been published in Spatial Economic Analysis. The paper is co-authored by Matthias Bürger and Thomas Brenner.



Concepts like regional innovation systems, innovative milieu and learning regions emphasise the positive contribution of intra-regional cooperation to firms’ innovation performance. This claim is, however, primarily backed by qualitative evidence, as few studies test this issue with quantitative approaches. Using data on co-application and co-invention of patents for 270 German labour market regions, this study shows that cooperation intensity and regions’ innovation efficiency are empirically associated in a negative way. This particularly concerns missing or very extensive inter-regional cooperation. In contrast, medium intensities of regional cooperation have rather positive effects.

New Ph.D. student

Schnappschuss (2014-10-11 00.00.38)I welcome Milad Abbasiharofteh in my team. As an external Ph.D. student he will joint our team and help analyzing networks from an evolutionary economic geography perspective. His preliminary thesis‘ title is: „Proximity, Knowledge, and Networks: a Dynamic and Evolutionary Approach to the Notion of `Local buzz‘ and `global pipeline‘„. I am looking forwarding working with him.



Similarity_ZoomI presented at the „7th Summer Conference in Regional Science“ in Marburg, Germany (26.6.-28.6.2014). The presentation’s title was „Subsidization of joint R&D, related variety, and regional innovation performance“, which summarizes the work I’ve done together with Matthias Brachert (IWH Halle), Matthias Duschl, and Thomas Brenner (both Philipps University Marburg).


New presentation

New presentation: I participated at the conference „Dynamiken räumlicher Netzwerkstrukturen“ in Darmstadt on June 12. – 13. 2014. Given the conference’s topic on „dynamics of network structures“, I chose to present the paper „The characteristics of critical links in knowledge networks“, which is co-authored with Wladimir Müller.


New publication

New paper has been published: Tom Broekel, Pierre-Alexandre Balland, Martijn Burger, Frank van Oort (2014) Modeling knowledge networks in economic geography: a discussion of four methods. Annals of Regional Science, DOI:DOI: 10.1007/s00168-014-0616-2

Abstract: The importance of network structures for the transmission of knowledge and the diffusion of technological change has been recently emphasized in economic geography. Since network structures drive the innovative and economic performance of actors in regional contexts, it is crucial to explain how networks form and evolve over time and how they facilitate inter-organizational learning and knowledge transfer.
