Technical efficiency analysis of intensive black tiger shrimp farmers in Gia Rai town, Bac Lieu Province

Abstract

This paper aims to measure the technical efficiency and determine the determinants of the technical efficiency of intensive black tiger shrimp production of farmers in Gia Rai town, Bac Lieu Province. Based on the survey results of 44 intensive black tiger shrimp farming households in Gia Rai town, the study uses Data Envelope Analysis (DEA) method to measure technical efficiency and scale efficiency. The results show that the average technical efficiency and the average scale efficiency of the intensive black tiger shrimp farming households are 59% and 79.9% respectively. The results of the Tobit model show that there are three factors that have a positive impact on the technical efficiency of intensive farming households, including education level, seed density and testing.
