Study on moderate scale of grain management in agricultural area of central plain based on DEA model:A case of wheat-corn rotation in Henan province

摘要：

以河南小麦-玉米轮作种植为例,运用农户调查问卷和DEA模型,对中部平原农区粮食生产适度规模进行测度,选取耕地、劳动、直接物资和间接分摊为4项投入指标和粮食总产量及生产净利润为2项产出指标,对不同农地规模农户的指标数据进行统计整理,测算综合效率、技术效率和规模效率,从而测度适度生产规模.同时,对不同规模分组的投入结构和产出特点进行分析,探索DEA有效分组特征及无效分组的原因.结果表明,不同种植规模农户投入结构有较大不同,普通种粮大户适度规模耕地面积在(3.67,4.67]hm^2,对基础设施健全、农业机械等固定资产投入量大的少数大规模种粮大户来说,最佳适度规模为(66.67,100.00]hm^2.通过研究,提出了选择适宜种植规模、利用规模优势繁育良种或者种植优质专用品种、加强社会化服务等政策建议.

Taking wheat-corn rotation in Henan as an example,farmers'questionnaire and DEA model were used to measure appropriate grain production scale of crop growing areas in Central China Plain.4 input indexes including land,labor,direct materials,and indirect materials and 2 output indexes including total grain yield and net profit were chosen,and the index data of different land scale farmers were counted and collected.Comprehensive efficiency,technical efficiency and scale efficiency were measured so the appropriate scale of production were found out.Meanwhile,input structure and output characteristics of different scale groups were analyzed,and characteristics of DEA effective group and the reasons of invalid group were explored.The results showed that there were great differences among farmers'input structure in different planting scale,and that the best cultivated area of general grain producers was(3.67,4.67]hm^2,and the most suitable scale for large scale grain producers who had large investment in infrastructure and agricultural machinery was(66.67,100.00]hm^2.Through the research,some policy recommendations were put forward such as choosing suitable planting scale,utilizing scale advantage to breed better seeds and plant high-quality special varieties,and strengthening social services,and so on.
