摘要
针对山东省青岛市胶州市马铃薯产区,运用DEA模型对胶州市10个村112农户马铃薯生产效率进行了实证分析。结果表明,村级实证分析无较大差异,农户层面生产效率差异巨大,运用非DEA有效投入产出分析得出农户化肥、农药和用工投入过剩,对优质种子了解程度低。从4个方面提出了相关政策建议,以提升胶州市马铃薯生产效率。
Targeting potato production area of Jiaozhou City,Qingdao City,Shandong Province,DEA model was used to empirically analyze potato production efficiency of 112 households in 10 villages in Jiaozhou City.Results showed that there was no significant dif-ference in empirical analysis at village level,and there was a huge difference in production efficiency at farmer level.Using non-DEA effective input-output analysis,it was found that farmers have excessive inputs in fertilizers,pesticides,and labor,and their under-standing of high-quality seeds was low.Relevant policy recommendations were proposed from four aspects to improve efficiency of potato production in Jiaozhou City.
