Este artículo propone la medición del grado de eficiencia de un sistema productivo mediante un enfoque basado en el concepto de Tasa de Crecimiento Uniforme de la Economía. Esta tasa se obtiene a partir del autovalor dominante de la matriz de coeficientes técnicos de la tabla input-output del país analizado. A su vez, el autovector derecho asociado a dicho autovalor indica la importancia de los diferentes sectores económicos en términos de su influencia sobre el nivel de eficiencia productiva del sistema. La metodología es aplicada al caso de los países pertenecientes a la Unión Europea. ; This paper suggests the measurement of the level of efficiency of a productive system by means of an approach based on the concept of Uniform Rate of Growth of the Economy. This rate is obtained from the dominant eigenvector of the matrix of technical coefficients of the input-output table of the analysed country. In turn, the right-eigenvector associated to such an eigenvalue indicates the importance of the economic sectors in terms of their influence over the level of productive efficiency of the system. This methodology is applied to the countries belonging the European Union.

We provide a multilevel logit model based on panel data which allows a capturing of the determinants of investment in their capacity for generating renewable energy in farms. As a novelty, we focus on regional determinants in order to assess the role of the regional dimension in making decisions by farmers about whether or not to invest in renewable energy generation. The relevance of this territorial/regional dimension acquires even greater significance in countries with a high degree of administrative decentralization, as is the case in Spain; where energy legislation gives a central role to regional governments in aspects related to the promotion of renewable energy sources. Multilevel analysis allows us to evaluate together both dimensions: Individual and regional. The results highlight the importance of the R & D investment carried out in regions, as well as the fact that there is an environment that favors the diffusion of renewable energies into the territory. Other variables, such as the level of agricultural income or regional energy intensity, do not seem to have significant relevance in the light of these results.
