摘要

本研究建立了一个理论模型来解释耕地整合和农业专业化。在该模型中，假定农民拥有关于每种作物生产的知识，这些知识通过学习不断发展。不同作物的知识具有不同程度的可替代性。农场规模分布和专业化被证明是由知识分布决定的均衡结果。本文以加利福尼亚州农场一级的种植面积数据为基础，提出了一个模拟实例，以说明学习机制的相关性并检验模型的含义。

Using the evolution of knowledge to explain changes in farm size distribution and specialization

This study developed a theoretical model to explain the consolidation of farmland and specialization in agriculture. In the model, farmers are assumed to be endowed with knowledge regarding the production of each crop, which evolves through learning. Knowledge across crops is substitutable to various degrees. The farm size distribution and specialization are shown to be equilibrium outcomes determined by the distribution of knowledge. A simulation example based on farm-level acreage data from California is presented to show the relevance of learning mechanisms and test model implications.
