استخدام أسلوب تحليل مغلف البيانات D. E. A لمحاولة قياس الكفاءة النسبية للبنوك المغاربية : دراسة قياسية 2012

الملخص EN

The purpose of the present study is to use Data Envelopment analysis DEA as a nonparametric method to measure the relative efficiency of a sample of 30 Maghrebian banks, based on two inputs : capital plus deposits and two outputs : loans and investments in 2012, using the model of Constant Returns to Scale (CRS).The findings show that the average efficiency of the targeted banks is around 66.36 %, of which four banks reached full efficiency index to 100 % relying on inputs and outputs orientation.

Where as the use of the Variable Returns to Scale model (VRS) relying on inputs orientation, results in an average efficiency index of 73.35 %, yet according to the output orientation, the average efficiency is 72.17 %, of which 10 banks have reached full efficiency index.

The results of the Tobit regression analysis of the two previous models demonstrate that the return rate on assets ROA is positively correlated with the level of efficiency; however, the latter is not affected by the size of the bank.
