The geography of EU green and digital inventions and their knowledge sources
Using a dataset of patent information for the period 2000-2017, this study provides evidence on the development of green and digital technological trajectories in the EU, at both national and regional levels. In particular, it explores how the distributions of the two technologies vary over time, as well as across countries and regions. It also provides evidence on the location of the knowledge sources relevant for the development of these technologies, which is captured using the patent citations of EU green and digital patent applications.
Findings of this document indicate that, while green technologies appear on average more diffused than digital ones, these technologies share similar geographical patterns. Their development concentrates in France and, even more markedly, in Germany, although there are signs of recent catching up of other EU countries, especially in digital technologies. At the subnational level, digital and green inventions in the EU appear to be driven by the core regions and Sweden. Quite interestingly, the citation analysis shows that the knowledge base for the development of both green and digital technologies is mainly located outside of the EU, and especially in the United States and Japan. Within the EU, Germany is the most important source of knowledge for green and digital technologies.
