The social and economic development of regions and cities needs the support ofdifferent stakeholders. Some of the most important stakeholders are entrepreneurs and private companies. Many of them have recognized the advantages coming from an international network and have therefore chosen to become stakeholders with the IRE. With their sectoral expertise, they represent an inestimable resource for the regions and cities. We have no restrictions in regard to these sectors – all of them can contribute to the strengthening of the decentralized level.
