The document discusses the 2014-2020 Partnership Agreement between the EU Commission and member states for implementing the Common Strategic Framework. It outlines the guiding principles, implementation approaches, and new instruments available under the agreement. While partnerships are meant to increase coordination, ownership, and transparency, there are challenges to effectively applying the partnership principle across different countries due to variations in institutions and political cultures. Implementing integrated territorial investments (ITIs) at domestic levels also faces challenges due to mismatches between governance and functional regions, and a history of poor territorial cooperation. Overall, the success of the partnership agreement will depend on balancing efficiency with legitimacy and overcoming issues of policy fragmentation, political accountability, and fitting objectives to appropriate instruments and scales of administration.
