ABSTRACT

A meta-analysis is substantial for integrating the findings of all related studies into one consistent research to establish a knowledge bank of a common issue. Although several studies have examined the impact of the individual aspect of human capital on farmers’ technical efficiency, the composite impact was not synthesized. Therefore, our analysis examines the key determinants driving systematic variations in technical efficiency estimates from 268 food-crop farming studies published recently in peer-reviewed journals. Our results have supported our hypothesis that human capital increases farming efficiency. The studies’ location indicates the importance of farmer beliefs, trust in their institutions and land accumulation to increase food-crop farmer technical efficiency. Our findings contribute to the applied agricultural economics literature by theoretically systematizing literature on human capital in accordance with social and natural capitals in agricultural productivity and empirically validating the technical efficiency in food-crop farming studies toward developing agricultural sustainability in harmony with our biosphere.

摘要

荟萃分析对于将所有相关研究的结果整合到一项一致的研究中以建立一个共同问题的知识库非常重要。尽管有几项研究考察了人力资本的个别方面对农民技术效率的影响，但并未综合综合影响。因此，我们的分析从最近发表在同行评审期刊上的 268 项粮食作物农业研究中，检查了驱动技术效率估计系统变化的关键决定因素。我们的结果支持了我们的假设，即人力资本提高了农业效率。研究地点表明农民信仰、对其机构的信任和土地积累对于提高粮食作物农民技术效率的重要性。
