CORINNA's aim is to help exploit the full potential for technological innovation of the partner regions by stimulating cross-border cooperation in fields of common technological strenghts or complementarities. To date, the intensity of collaboration in technology and innovation across the borders between Italy, Slovenia, Austria and Hungary still lacks behind that of other comparable regions. Huge differences in governmental structures – federalistic or centralistic – regulations, policies and support programmes as well as language barriers and restructuring processes hinder efficient cooperation on policy as well as on company levels.
