El presente trabajo recoge los resultados de una investigación en la que se estiman la Eficiencia técnica y el nivel de innovación de una muestra de explotaciones agrarias multicultivo, situadas en la provincia de Córdoba. Para la primera, se aplica la metodología de función frontera estocástica. El nivel de innovación se calcula como índice compuesto de otros tres, que revelan niveles tecnológicos en los siguientes aspectos: gestión, maquinaria y técnicas de cultivo. Los resultados obtenidos muestran la ausencia de relación entre las medidas de eficiencia e innovación aunque el tamaño de la explotación y la pertenencia a asociaciones agrarias son factores que se asocian con ambos. Cabría pues afirmar que, y para este caso, los indicadores de eficiencia e innovación son complementarios y la construcción de ambos permite profundizar mejor en el conocimiento de la estructura productiva en la zona. This work presents the results of research carried out in order to estimate the technical efficiency and innovation level in a sample of multicrop farms in the province of Córdoba. The stochastic frontier model is applied to calculate the latter, the former being achieved as a compossed index that collects the technological level of the studied farms in the three following aspects: management, machinery and agricultural techniques. We have found that there is no relation between efficiency and innovation, but there are two factors associated with both indexes. They are the size of the farm and being a membership of an agrarian association. Therefore we conclude that, as far as this zone is concerned, efficiency and innovation may be considered as complementary. For this reason, each provides us a valiable means of acquiring a better knowledge of the productive structure of the zone.
