[eng] French banks are technically efficient: an application of DEA In this paper, we first address the issue of the nature of inputs and outputs when banking activity is considered. We suggest to use a decision rule using the sign of the derivatives of the profit with respect to its arguments. We, then, turn to an empirical analysis of 38 French banks during years 1994-97. Using Data Envelopment Analysis together with our new classification leads to the following results: (i) our estimates of technical efficiency appear to be far above and, consequently, more realistic than former scores and (ii) inefficiency is not a good explanation for the low profitability of French banks. [fre] Notre premier propos, théorique, est d'élaborer une règle de classification en intrants et en extrants des différents arguments de la fonction de profit bancaire. Nous l'utilisons ensuite dans notre étude empirique de 38 banques françaises de réseau. La technique retenue est celle de l'enveloppement des données (DEA). La période étudiée (1994-1997) correspond à celle d'une grande faiblesse de la rentabilité des banques françaises. Les résultats que nous obtenons, plus réalistes que ceux d'études antérieures comparables, nous conduisent à conclure que les banques françaises de notre échantillon n'ont pas de problèmes majeurs d'inefficacité productive et que l'explication de leur sous-rentabilité se situe donc ailleurs.
