Abstract

This study aims to analyze the production efficiency and identify scale properties of shrimp poly-culture farms in Tam Giang-Cau Hai Lagoon, Thua Thien Hue Province, Vietnam by applying Data Envelopment Analysis under inputorientated approach. In addition, the extension Cross Efficiency Method was undertaken to have better ranking of farm performance, to which the comparisons of the uses of inputs between the truly efficient and inefficient farms were made in order to help farms to properly adjust their input combination to optimal level. It is found that if farmers follow the recommendation by this study, the optimization of inputs configuration tends to decrease the total costs of production by 141.85%, and increase the benefit-cost ratio by 58.79%.
