Abstract

This study examines the impact of land tenure systems on aquaculture farm productivity, efficiency, and profitability based on information obtained from interviews with 517 randomly selected aquaculture farms across Bangladesh. Propensity score matching (PSM) is used to estimate productivity variation, and the stochastic frontier production function (SFPF) is employed to analyze efficiency variation depending on aquaculture farms’ land ownership. The results reveal that the productivity and efficiency of cash tenant farms are significantly higher than those of self-owned farms, but that the land-owner extracts most of the associated profits through the rent. Furthermore, the efficiency of self-owned farms decreases with farm size, while the opposite is true for cash tenant farms.

摘要

本研究根据对孟加拉国 517 个随机选择的水产养殖场的采访获得的信息，检验土地使用权制度对水产养殖场生产力、效率和盈利能力的影响。倾向得分匹配（PSM）用于估计生产力变化，随机前沿生产函数（SFPF）用于分析取决于水产养殖场土地所有权的效率变化。结果表明，现金佃农农场的生产力和效率明显高于自有农场，但土地所有者通过租金提取了大部分相关利润。此外，自有农场的效率随着农场规模的增加而降低，而现金租户农场则相反。
