Innovation economics

How can heterogeneous texts (such as patents, scientific publications or media reviews) on the innovation process and socio-political discourse be linked in the context of Clean Circles? Using AI methods, sources that were previously analysed in isolation are linked and semantically analysed (NLP; topic modelling). This enables a completely new kind of integration of the most diverse dimensions of the innovation process. For this purpose, a suitable tool is being developed that integrates the different perspectives (technological, political, economic, social) of Clean Circles.

Innovation economics perspective:


  • General equilibrium model that analyses the spatial distribution of economic activity in a two-region context as a function of various policy objective functions.
  • Determination of objectives/actors/instruments
  • Direction and strength of impact
  • Implication of policy interaction (national/supranational) and link back to regional distribution of economic activity.

Adaptation of the model to the specifics of Clean Circles

  • Implementation of heterogeneous regions (global North, global South);
  • Provision of global public goods,
  • Identify and parameterize innovation drivers and barriers;
  • Derive economic policy recommendations


  • Develop knowledge graph in the context of the question
  • Basic and applied knowledge: who are the actors (personal/regional)
  • Content overlap based on semantic analysis
  • Relative location of iron storage technologies in the context of energy storage systems
