摘要：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.
