Resumen
Abstract: From the cross-sectional data of 94 oyster mushroom farms in Quang Tri province, this study estimates and compares technical, allocative and cost efficiency of the irrigation water from a factory and from wells by using Bootstrap input-oriented Data Envelopment Analysis. The empirical results indicate that oyster mushroom farms are substantially inefficient. The farms that use the irrigation water from a factory are more statistically efficient than those using the water from wells. The mean technical, allocative and cost efficiency of the irrigation water from a factory and from wells is 0.62, 0.58, 0.34 and 0.58, 0.52, 0.26, respectively. Therefore, shifting to use the water from a factory to irrigate oyster mushrooms is one of the proposed recommendations.Keywords: efficiency, oyster mushroom, bootstrap input-oriented Data Envelopment Analysis
