Abstract
The research stems from the problem that focuses on a number of questions. They are as follows: What is the extent of interest in the topic of efficiency by the banks and their role in raising the efficiency of the banking business and its development? Is the banking efficiency used in Iraqi banks clear and specific for the Iraqi banking sector? How the banking sector efficiency is measured and what are the approaches adopted in determining the banking inputs and outputs? What is the level of efficiency in the research sample of the banks and what are the causes of its decline or rise in private banks individually and in the Iraqi banking sector in general?
The research aims to measure the efficiency of the performance of banks and the distinction between levels, for the purpose of benchmarking comparison, in addition to that analyzing relationship and effect of efficiency on the banking performance for research sample of the banks. Therefore, the research hypotheses were formulated to study and analyze the relationship and effect of efficiency on banking performance of the banks of the research sample. The data envelopment analysis method has been used to extracting the technical efficiency indicators of constant and variable returns volume model, and the use of variable returns volume model to extracting the volume efficiency indicator, in addition to the use of a set of financial indicators of the ratios (profitability, liquidity and solvency) to study banking performance. The research results have showed that seven banks have achieved the full efficiency which are (Baghdad bank, Iraq's commercial bank, Iraqi investment bank, Dar Alsalam for investment bank, Sumer Commercial bank, Mansour Investment bank and the Iraqi Union bank), according to the constant and variable returns volume model, this means that most banks have not reached the best managerial practices through producing the maximum possible amount of outputs as a result of using a certain amount of inputs, i.e., achieving the maximum production possible of production factors
