Investigating the Efficiency of Shrimp Cooperatives and Non-cooperatives Companies Using Data Envelopment Analysis Technique in Chabahar City in Iran (Application of CCR and FDH Models)

Abstract

The purpose of this study is to assess the efficiency of Shrimp cooperatives and non-cooperatives companies in Guatr site of Chabahar County in the province of Sistan and Baluchistan in 2010. Therefore technical efficiency of shrimp farms was obtained by using the primary model of Data Envelopment Analysis (DEA) and Free Disposal Hull (FDH) model. Considering the number of units, census was conducted, and eventually the questionnaires of the entire population (25 units) were collected. The results showed that only 12% of firms in the primary model and 16% in the FDH model are quite efficient, and the average of technical efficiency for units is 85 and 87 percent respectively. Strategic approach to issues and adopting fundamental changes in production process, such as adding aeration systems in the fields with assistance from government agencies can improve the efficiency of the inefficient firms. Due to heavy costs brought about by the frequent use of aeration systems, the demand for these systems is low in the farms; therefore it is recommended that relevant institutions such as Province Fishery Organization and Province Department of Cooperation make necessary arrangements for banks to provide managers of shrimp farms with low-interest loans
