This paper assesses the distributional consequences of technical changes that improve the efficiency of land and of other inputs in a multifactor crop‐production system. We introduced an equilibrium displacement model (EDM) by using the specification of a factor‐augmenting approach. Given the uncertainty about the EDM parameters, a Monte Carlo simulation is used to produce a distribution of possible return measures. We found that land suppliers (likely farmers) receive a larger share (73%) of total benefits from the adoption of land‐technical change than they do from the adoption of other input technologies. Each input supplier receives a larger share of total benefits from technical change in her own input. However, this result is sensitive to the value of the parameters, especially the value of the elasticity of substitution. We applied the EDM to the case of no‐tillage (NT) to provide insight into how the aggregate return from the adoption of NT was distributed among different groups on the Canadian Prairies. The results of this study can be used by policymakers and funding agencies in order to influence landowners and farming communities to adopt environmentally sound land technologies to achieve both greater agricultural productivity and sustainability.

多阶段生产系统中土地效率改善的收益分配

本文评估了技术变革的分配结果，这些技术变革提高了土地生产效率以及多要素作物生产系统中其他投入的效率。通过使用因子增强方法的规范，我们引入了平衡位移模型（EDM）。给定有关EDM参数的不确定性，可以使用Monte Carlo模拟来产生可能的退货措施的分布。我们发现，土地供应商（可能是农民）在土地技术变更中所占的总收益比在其他输入技术中所占的份额更大（73％）。每个投入品供应商从自己的投入物中获得的技术变更所获得的总收益中，份额更大。但是，此结果对参数值特别是替代弹性值敏感。我们将EDM应用于免耕（NT）案例，以深入了解采用NT的总收益如何在加拿大大草原上的不同群体之间分配。决策者和资助机构可以使用本研究的结果，以影响土地所有者和农业社区采用无害环境的土地技术，以实现更高的农业生产力和可持续性。
