Shrimp is the most traded food commodity in the world; the majority of it was sourced from farming. Shrimp farmers need to be technically efficient to be globally competitive. We measured the technical efficiency of shrimp farms with a stochastic production frontier to identify the socio‐economic characteristics and input variables that determine it. The model is applied to small‐scale shrimp farmers (n = 150) in Nellore District of Andhra Pradesh, India, by using primary survey data that collected through adopting random sampling with the pretested interview schedule. The average technical efficiency score of 0.95 indicated that the farmers were the most efficient. The finding of the technical efficiency score suggests that strengthening the education, experiences, technological adoption and membership of the society could further enhance the shrimp production about 0.44 tons ha⁻¹ with existing technology and alternating inputs.

通过随机生产前沿方法评估虾类养殖的投入使用效率

虾是世界上交易量最大的食品。其中大部分来自农业。虾农需要技术上有效，才能具有全球竞争力。我们测量了具有随机生产边界的虾场的技​​术效率，以识别其社会经济特征和决定其的输入变量。该模型适用于小型虾农（n = 150）在印度安得拉邦内洛尔区，方法是使用主要调查数据，这些数据是通过对预先测验的访谈时间表采用随机抽样而收集的。平均技术效率得分为0.95，表明农民的效率最高。技术效率得分的发现表明，利用现有技术和交替投入，加强教育，经验，技术采用和社会成员资格可以进一步提高对虾产量，达到约0.44吨ha ^-1。
