| With a sample of nearly 18,611 utility patents, this paper studies the technology mix of 90 of the world's leading food and beverage multinationals (FBMs) over 1969-1994. It explores the statistical association between patenting in food technology and in non-food technological fields. Food patenting is always associated with patenting in Biotech, Chemistry, Machinery and Other patenting, whatever the home country of the company. The strength of the association, however, could vary. Herfindahl indices show that capabilities in core technology and in Machinery and Other fields are spread among many FBMs. Though to a lesser extent, technical capabilities in Biotechnology, Packaging and Refrigeration are also dispersed. By contrast, patenting in Tobacco,... |

| The main objective of the paper is to examine and discuss the nature of technological relationships across agrifood sectors in order to understand better the pattern of technological changes in the Food and Beverage sector. We propose a new estimator to confirm the existence of linkages between technological sectors (the Technological Concentration Index). A central conclusion from this work is that the quality of data is a principal determinant in the measurement of technological flows, and that probably the use of raw patent data could introduce a distortion in the qualification of the consequences of technological spillovers. |

| Las multinacionales agroalimentarias son las principales innovadoras del sector agroalimentario mundial y agentes económicos fundamentales del cambio tecnológico en el sector agroalimentario español. El estudio del comportamiento innovador de las multinacionales agroalimentarias presenta interés puesto que el 50% de la tecnología relacionada mundialmente con la alimentación procede de este tipo de empresas. Basándonos en una muestra de más de 16.000 patentes concedidas, entre 1969-94, a las mayores empresas multinacionales alimentarias y en los resultados de diversos estudios recientes, este trabajo aborda algunos de los principales aspectos de la innovación en estos importantes agentes económicos, tales como la globalización de sus actividades... |
