Measurement of technical and economic efficiency and determine the economic size of wheat farms in Erbil using the data envelope analysis method (dea) in agricultural season 2014-2015
AbstractThis research have its importance from the strategic importance of wheat, And that different cases of area for wheat farms reflects on the economic and technical efficiency, As the area impact on production costs with respect to the use of machinery work upon which mainly in rain-fed agriculture in Erbil research topic, And research assumes the existence of at least one class of area is characterized by a high level of total efficiency estimated for the other classes , So was the study of the economic efficiency of utilization of resources as one of the goals of the economic systems to improve the economic performance of farms, In order to determine the optimal farm size within the category achieved the optimum size of the use of resources, Use the envelope method of data analysis (Data Envelopment Analysis) (DEA), Data was collected by the questionnaire and personal interviews to farmers in the sample of 222 farm is divided into five categories according to farm size , And use trends in the analysis of this data type style, first trend is using a method (DEA) on according to variable returns to scale (Variable Return to Scale) (VRS), and according to the constant of returns to scale (CRS), (Constant Return to Scale, The research concluded that where the greater size of the area categories decrease the losing in the of productive resources clearly, which goes with what came in economic theory for it with increased production volume increases the marginal productivity of land unity, Taking that pattern in wheat farmer in Erbil is the pattern of the family farm, which takes into consideration not to break up large areas, especially among members of one family to achieve economic efficiency and technical exploitation of the productive resources, especially with regard to the machinery and agricultural machinery.
