The participating regions have all decided to support as part of their ERDF Programme and RIS3 the field of “advanced materials”. This Key Enabling Technology complements the regional economic and research tissue with a stable opportunity for future growth and jobs. 6 regions/ countries (Bremen, Aquitaine, Podkarpackie, Piemonte, Denmark, Lithuania) cooperate with their local Stakeholders. P2L2 applies interregional policy learning and exchange of experiences on important aspects influencing the regional innovation ecosystems in the field of advanced materials. Concrete aims are: • Improving policy instruments supporting innovation ecosystem of advanced materials (support to RTD projects, cooperation between science and industry, the creation of infrastructures and mobilise actors for improving innovation ecosystems, networks, processes); • Improving policy instruments related to the implementation and evaluation of the smart specialization strategies (reviewing the whole process for definition, implementation and evaluation of smart specialization strategies); • Coordinate/ align regional policies and strategies between sectors in order to facilitate the establishment of real innovation ecosystems beyond administrative regional boundaries (for example in the triangle Bremen-Hamburg-Niedersachsen or Aquitaine - Limousin - Poitou-Charentes). P2L2 goes beyond traditional 'good practice sharing' and results are expected not only to improve policy instruments selected for increasing growth and innovation rates. The project will deliver a “limited mapping” tool and add value by aligning S3 strategies within one field (Advanced Materials) between different regions to identify overlaps, gaps, complementarity and opportunities for European collaboration (including support from regional policy level). Therefore we involved 2 supra-European bodies and will organise a special “Action Plan Conference”.
