Résumé

In aggregate perspective, this paper analyses the productive efficiency of 501 Spanish agri - food co - operatives over 2014 - 2017 period, covering 22 main activities and 4 different co - op era tive sizes. The focus is on the efficient use of resources to obtain goods and services for whic h three ratios are obtained, for each co - operative, between factor and product. This is a measure of factor use and the inverse is an efficiency measure. Fur the rmore, a non - parametric efficiency is obtained using Data Envelopment Analysis (DEA). Efficienci es estimated using DEA are relative, that is, relative to the best performing. A comparison of results is made assuming that the operations follow both const ant returns to scale (CRS) and variable return to scale (VRS). The results are given aggregate by c ooperative main activity, by cooperative size and by region. Finally, and due to the importance of the sector in Catalonia, a comparison between Catalan agri - fo od co - operatives efficiencies and the rest of Spanish agri - food co - operatives efficiencies is pr esented. In the efficiency values calculated by the DEA, no biases are observed in efficient cooperatives, which are both large, medium and small size. In ge ner al, it has been observed an increase in the average efficiency of the activity groups, between 2 014 and 2017, both with RCE and with RVE. The efficiency scores for Catalonian co - operatives and for the rest of the Spanish co - operatives are very similar, alt hough efficiencies of fruits and vegetables and animal food co - operatives are smaller in Catalon ian than in Spanish ones .
