基于DEA模型的粮食生产型家庭农场的适度经营规模

Moderate Operation Scale of Grain Production Family Farms Based on DEA Model

为合理确定粮食生产型家庭农场的适度经营规模,更好地促进家庭农场的健康发展,以南京市6个涉农县(市、区)粮食生产型家庭农场的专项调查数据为基础,运用DEA模型估算其适度发展的经营规模。结果表明:南京市粮食生产型家庭农场的水稻和小麦适度种植规模分别为53.34～66.67hm^2和26.68～33.33hm^2,即粮食生产型家庭农场的水稻和小麦种植规模必须达到合适规模才能使生产的投放产出效率达到最大;粮食生产型家庭农场的经营规模合适,能降低粮食单位面积的生产成本、提高农业生产率、增加生产经济效益。

To rationally confirm the moderate operation scale of grain production family farms, and preferably promote their healthy development, in this paper the authors use the data of special survey on grain production family farms in Nanjing, and make an estimation on the moderate operation scale of grain production family farms through DEA model. Results： The moderate operation scale of rice and wheat planting area is 53.34-66.67hm2and 26.68-33.33hm2 respectively. In other words, the ptanting scale of rice and wheat production family farms reaches the suitable scale when the output efficiency can reach maximum,As a result, the moderate operation scale of grain production family farms can reduce the production cost of per unit area, and increase the agricultural productivity and production economic benefits.
