Regional Aspects of Collaborative Invention Across National Innovation Systems

This article analyzes the association between intraregional collaboration and levels of invention in nine developed countries. Patent data of the Organization for Economic Co-operation and Development (OECD) regions of nine inventive countries are used to determine if a significant positive correlation exists between reliance on own region partners and overall invention. Strong intraregional collaboration is also related to the knowledge bases of technologies and to the tendency for inventors to team up in the first place. Results show strong evidence that inventors in highly inventive regions co-patent more with own region partners and that they have a greater tendency to collaborate in the first place. Support for the hypothesis that information and computer technologies favour own region collaboration and that more biotechnology invention encourages external alliances is mixed. However, there is far less evidence that more biotechnology invention encourages more external alliances. Variation in the results between countries is interpreted as evidence that national innovation systems have distinctive internal locational attributes. The findings refute the assertion that strengthening aspatial network proximities has eclipsed the pivotal role of intraregional linkages in technological advance.
