A Pragmatic Study for Enhancing Agricultural Efficiency Through Labor Freedom

The study aims to explore labor freedom in the agricultural sector for enhancing the efficiency of farming through policy change towards assigning property rights, rental contracts, and better wage-employment options to rural workers. Labor freedom emphasizes land reform and development policy for improving the economic status and capabilities of rural workers. The paper assessed the labor freedom index, weighted through agricultural property rights, labor wage contracts, and rural development policy. Data envelopment analysis is used to assess farm-level efficiency under the framework of Tobit regression for different size-based farm categories. Farm-level information was collected through a primary survey of 336 rural households of an advanced agricultural state in India. The study found a positive association between farm size and intensity of labor freedom, although the extent of freedom differs among farms. Size-specific variation was also observed for allocative efficiency such that marginal and medium-sized farms are more efficient than smaller ones. Tobit regression indicated labor freedom to be positively and significantly related to the efficiency of marginal, small and overall farms with enhancing efficiency of 25, 17 and nearly 20%, respectively; however, estimates of labor freedom insignificantly increased the efficiency of mediums farms, by 4.8%. This result suggests that labor freedom positive and significantly affects the efficiency of farms in general, and marginal and small farms in particular. Of course, the elasticity estimate of enhancing efficiency through labor freedom for medium farmers is found at a lower level.本研究聚焦农业领域的劳动自由（labor freedom）议题，旨在通过政策调整为农村劳动者赋予产权、租赁合约及更优的薪酬雇佣选择权，以此提升农业生产效率。劳动自由核心指向土地改革与发展政策，旨在改善农村劳动者的经济地位与综合发展能力。本研究以农业产权、劳动薪酬合约及农村发展政策作为权重因子，对劳动自由指数进行评估测算。本研究采用数据包络分析（Data Envelopment Analysis，DEA），结合托比回归（Tobit Regression）框架，针对按经营规模划分的各类农场评估其生产效率。农场层面的相关信息来源于对印度某农业发达邦336户农村家庭的实地调研。研究发现，农场经营规模与劳动自由强度呈正相关关系，但不同农场的劳动自由程度存在差异。配置效率（allocative efficiency）也存在规模异质性：边际农场与中等规模农场的效率高于小型农场。托比回归结果显示，劳动自由对边际农场、小型农场及整体样本农场的生产效率具有显著正向影响，分别可提升25%、17%及近20%的生产效率；然而，劳动自由对中等规模农场的效率提升效应并不显著，仅提升4.8%。上述结果表明，总体而言劳动自由对农场生产效率具有显著正向影响，尤其对边际农场与小型农场的影响更为突出。当然，劳动自由对中等规模农户的效率提升弹性估计值处于较低水平。
