Planting on each field plot was recognized with an integration of GIS and satellite images. Abandoned farmland plots were observed disorderly in each year. Approximately half of the terrace plots were farmed by small farm household with less than 1 ha. Our estimation with small output area statistics of the Agricultural Census clarified that small and elderly farmers input a great deal of labor on rice production and at least 70% of the field can be substituted by productive age farms if they enlarge farm size. The result of multinomial logit model estimation of cultivated field plots by different farm size suggests that large scale farm operation in relatively flat areas can readily rent field if the field is close to the farm. In steep areas, on the other side, even the middle size operation with 2 to 3 ha can be more probable in renting field than large farms depends on the distance to the field.

通过地理信息系统和卫星图像的集成来识别每个田块上的种植情况。每年都会出现废弃农田乱七八糟的情况。大约一半的梯田是由面积不足 1 公顷的小农户耕种的。 我们根据农业普查小产区统计数据推算，小农和老年农户在水稻生产上投入了大量劳动力，如果扩大农场规模，至少70%的土地可以被适龄农场取代。 对不同农场规模的耕地进行多项logit模型估计的结果表明，在相对平坦地区的大规模农场经营如果距离农场较近，很容易租用土地。 另一方面，在陡峭地区，即使是 2 至 3 公顷的中型农场也比大型农场更有可能租用田地，具体取决于距田地的距离。
