随着出生率下降和人口老龄化，日本的农场也在减少，但它们的平均规模正在增加。在农业发达的北海道十胜，随着老年农民停止耕作，平均农场规模增加。典型的农民种植四种作物，如小麦，豆类，甜菜和土豆，主要通过轮作。小麦的单位面积利润率较低，但与其他作物相比，它是一种节省劳动力的作物。甜菜和马铃薯的单位面积利润率较高，而且比其他作物的劳动密集度更高。在土地和劳动力有限的情况下，农民决定他们的作物分配，以最大限度地提高他们的收入。以前的研究报告说，当农场规模增加时，甜菜和土豆的面积会下降，而小麦等节省劳动力的作物的面积会上升。已经指出，这种作物结构的变化降低了农民的单位面积收入。
With a declining birth rate and aging population, Japan is also seeing a decrease in farms, but their average size is increasing. In Tokachi, Hokkaido, which is an advanced agricultural area, the average farm size increases as elderly farmers stop farming. Typical farmers grow four crops, such as wheat, beans, sugar beets, and potatoes, mainly through crop rotation. Wheat has lower profitability per unit area, but is a labor-saving crop compared to others. Sugar beets and potatoes have higher profitability per unit area and are more labor-intensive than the other crops. Farmers decide their crop distribution to maximize their income under land and labor limitations. Previous studies have reported that when farm size increases, the areas for sugar beet and potatoes fall, and those for labor-saving crops such as wheat rise. It has been pointed out that such a change in crop structure decreases farmer income per unit area.
