Abstract For a long-term growth in shrimp farming, a significant increase in shrimp output can only be fully realized by improving both technical and cost efficiency. This study employs data envelopment analysis with the double bootstrapping technique to analyze cost and technical efficiency for aquaculture. This procedure allows statistical inferences about cost and technical efficiency to be made. The case of intensive white-leg shrimp farming in Ninh Thuan, Vietnam is used for analysis. The result shows that the bias-corrected cost and technical efficiency were 0.533 and 0.723, respectively. From a policy perspective, it means that there is considerable room for improvement in cost and technical efficiency in the case of intensive white-leg shrimp farming. Such gains are certainly greater than for those using conventional data envelopment analysis, which has been widely adopted in the aquaculture literature. Regression analysis reveals that credit constraints for operational cost have a statistically negative influence on both cost and technical efficiency in this type of aquaculture.

数据包络分析和双引导技术在水产养殖成本和技术效率分析中的应用：信用约束重要吗？

摘要 要实现对虾养殖的长期发展，只有提高技术和成本效率，才能全面实现对虾产量的大幅增长。本研究采用数据包络分析和双引导技术来分析水产养殖的成本和技术效率。该程序允许对成本和技术效率进行统计推断。以越南宁顺的集约化白腿虾养殖为例进行分析。结果表明，偏差修正成本和技术效率分别为 0.533 和 0.723。从政策的角度来看，这意味着在集约化白腿虾养殖的情况下，成本和技术效率还有相当大的提升空间。这种收益肯定比使用传统数据包络分析的收益更大，传统数据包络分析已在水产养殖文献中被广泛采用。回归分析表明，运营成本的信贷约束对此类水产养殖的成本和技术效率具有统计上的负面影响。
