The new RIMES model : input-output tables and a scenario framework at the German district level

A successful energy transition requires systemic changes and long-term investment in energy, heating and mobility systems. It must be implemented successfully at a regional level. To demonstrate the regional impact, detailed modelling of regional conditions is necessary. To this end, we have developed a multi-regional input-output model (RIMES), which maps regional dependencies and sectoral structures at district level in Germany. This model covers all 400 NUTS 3 regions (districts and independent cities), each comprising 37 industries. The modelling follows the principles of the standard MRIO approach. Trade structures between sectors in various districts are determined using a gravity trade model.The RIMES model is a powerful tool for linking regional economic structures with the challenges and opportunities of Germany's energy transition. This enables strategic planning and policy evaluation.
