摘要
利用全国25个省2186份玉米种植户的实地调查数据评估玉米收获环节的损失率,并利用OLS模型和Tobit模型分别分析影响农户收获损失的影响因素,其中影响农户收获环节玉米损失的原因有户主年龄、户主文化程度、玉米商品化率、收获方式、收获时作业精细度和收获时人手充裕度。从提高农户文化程度、改进玉米收获机械的工艺水平和提高收获人员的作业态度提出政策。
The data from 2186 maize farmers in 25 provinces were collected to evaluate the yield loss rate dur-ing harvest.OLS and Tobit models were respectively employed to analyze the influencing factors for maize yield loss.The influencing factors mainly include age of householder,educated degree of householder,commercialization rate of maize,harvest method,work fineness degree and labor abundance or not.Then we put forward policy sugges-tions from three aspects:enhancing farmers’educated degree,improving maize mechanical harvest technology and operator’attitude.
