Repeated collaboration of inventors across European regions

Abstract

This paper explores the spatial patterns and underlying determinants of repeated inventor collaboration across European NUTS 3 regions. It is found that only a small fraction of co-inventor linkages across regions are repeated, while community detection reveals that these collaborations are clustered in geographical space more intensively compared with collaboration in general. Additional results from gravity modelling indicate that links in the interregional co-inventor network emerge mainly through the triadic collaboration of regions, while geographical proximity becomes the most influential factor for repeating co-inventor ties. In addition to that, the combination of technological similarity and shared third partner regions offer a premium for the likelihood of repeating a collaboration, but only when geographical proximity is present as an enabler. Hence, repeated inter-regional co-inventor collaborations are more likely to revert to spatial clustering, contributing to the fragmentation of the European Research Area.

A hálózati pozíció és a regionális innovációs teljesítmény kapcsolata a térbeliség figyelembevételével

“…A fokszám központiság azt jelöli, hogy adott régió szervezetei hány másik régió szervezeteivel léptek kapcsolatba (Freeman 1978). Ez a mutató nem veszi gyelembe azt, hogy milyen erősségű és intenzitású a kapcsolat, esetleg meggyelhetőek-e többszörös, ismételt kapcsolatok a hálózatban, holott ez lehet, hogy többletinformációval szolgál (Tóth et al 2021). Ennek következtében a projektek számával súlyozott értéket is bevontuk a modellbe, mely segítségével nemcsak a régiók között meglévő kapcsolatok meglétét tudjuk modellezni, hanem azt is, hogy adott régiók között milyen intenzitású a fennálló kapcsolat.…”

Investigating Company’s Technical Development Directions Based on Internal Knowledge Inheritance and Inventor Capabilities: The Case of Samsung Electronics

“…In a scholarly data analysis, inventors or authors are important bibliographic information for various research purposes. Since R&D human resources can represent the scientific and technical capability of organizations, their co-occurrence relations with other bibliographic information, such as a country, organization, or research field, can be used for better understanding the collaboration trends [48][49][50], regional characteristics [33,[51][52][53][54][55][56], or technical changes and innovation [33,54,[57][58][59][60][61]. In particular, co-inventor relationships within an organization can show some significant inventors who are strategically allocated to major R&D projects and so usually lead most R&D projects.…”

The influence of proximity and knowledge base on recombination innovation in R&D collaboration

“…First, in the existing literature, proximity and collaborative innovation are directly linked in theorization, while the underlying transmission mechanism is, to a large extent, black-boxed [ 13 , 14 ]. In the economic geography literature, studies have investigated various proximity dimensions, and their effects on the formation and maintenance of collaborations in the context of inter-regional [ 15 ] and inventor collaboration [ 16 ]. In addition, the effect of proximity on the knowledge sharing and production in inter-organizational alliance is well documented [ 10 ].…”
