TraCS3 project addresses challenges how to improve the support for regional innovation infrastructure, its better employment and involvement in innovation values chains, increase innovation capacities to build innovation and research excellence in the regions and how to enable interregional collaboration to help the regions open up their innovation potential to the world. Regional innovation infrastructures and innovation capacities are the backbone of dynamic regional innovation eco-systems. To innovate, industry, especially SMEs, partly rely on research and innovation institutions, their capacities to provide access to the necessary technology infrastructures for upscaling, prototyping and validation of new solutions before they can enter the market. In this context, partners will look for ways to stimulate the development and utilisation of innovation infrastructures, to find gaps, look for opportunities to address them and support further collaboration between existing infrastructures increasing innovation capacities. Seeking to strengthen regional innovation potential through the interregional collaboration, partners will explore opportunities to establish/improve financial schemes for the ERDF use outside programmes' area. The project objective is to improve regional policies in support of innovation infrastructure in S3 key priority sectors with strong innovation potential addressing the societal challenges and enhancing interregional cooperation within and between emerging and expanding innovation eco-systems. Partners jointly work towards creation of favourable environment for supporting integration of innovation infrastructure into interregional/international value chains and knowledge networks and an increase of innovation capacities. The main project outputs are: 51 interregional learning events,7 Action Plans addressing 6 ERDF and 1 regional policy instruments, at least 14 good practices analysed and shared,95 people with increased professional capacity
