Abstract

This paper investigates the relationship between ICT and international R&D collaborations among 19 OECD countries from 2000 to 2015. More specifically, it looks at the impact of broadband penetration on the number of international co-inventions measured through patents. Poisson and Negative binomial regression models are employed for estimation. The results reveal a non-linear association between broadband access and international R&D collaborations, characterized by an inverted U-shaped curve. Additionally, the insights show that broadband penetration increased the concentration of existing and new collaboration ties. Subsequent analysis is undertaken, splitting the overall country-pairs sample into seven technology areas using the OST7 classification. Consistent with the overall findings, Electronics, Instruments, Chemicals, and Pharma exhibit the same inverted U-shaped relationship. However, the relationship is non-significant for Industrial and Mechanical Processes, while Civil engineering displays a positive linear association. These results also underline how crucial it is to consider particular technology areas when assessing how technology adoption affects international R&D collaboration.
