When designing structural reforms for rural areas, the regional dimension is crucial. This study implemented a multi-directional efficiency approach in a regional, rural development context with the aim of analyzing the regional efficiency of agricultural resources. The efficiency patterns of each input and output were observed over three Common Agricultural Policy (CAP) periods (1998-2013). Efficiency of labor, assets and diversified output vary the most. Over the CAP periods, the efficiency gap across the counties decreases, indicating that changes in the policy help for regions cohesion. Future policies should keep compensating for generation of public goods, and creating opportunities for diversification.
