- 摘要:
- 基于微观种植户的调查数据，运用DEA分析陕西省猕猴桃种植户技术效率，在此基础上，利用Tobit模型对其影响因素进行实证分析。进而提出了拓展销售渠道、加强基础设施建设、推广关键技术的配套使用、重视种植户培训工作、鼓励土地流转和提高果品质量监管等政策建议。结果表明：1）样本猕猴桃种植户的平均技术效率水平较低，种植户在生产技术效率上仍存在较大改进空间；2）影响技术效率的内生因素，主要是灌溉和套袋投入、肥料投入、农药投入要素的冗余；3）技术效率的外生影响因素为种植户接受培训的次数、猕猴桃收入占比、膨大剂使用情况和猕猴桃树龄对技术效率具有显著正向影响，户主年龄则具有显著负向影响，户主受教育水平、家庭猕猴桃劳动力人数、家中是否有村干部、猕猴桃地块数、是否加入合作社则无显著的影响。
- Abstract:
- Based on the growers′ micro survey data,analyzed technical efficiency of kiwifruit growers in Shaanxi by DEA model,then analyzed factors influencing technical efficiency by Tobit model.The results showed that,firstly,the average level of technical efficiency of sample kiwifruit growers was low，there was still room for improvement in technical efficiency.Secondly,the internal factors which led to the growers′ technical inefficiency was the input redundancy,the main input redundancy were irrigation and bagging,fertilizer and pesticide.Thirdly,training times,kiwifruit income ratio,swelling agent use and the age of kiwifruit tree had significant positive effects on technical efficiency of kiwifruit growers;the influence of household age was negative;household education level,the number of family kiwifruit laborers,whether there were village cadres,number of plots,whether joined the cooperative had no significant effects.Finally,put forward suggestions:expanded sales ways,strengthened infrastructure construction,promoted the use of key technologies,payed attention to the training of growers,encouraged land transfer and improved fruit quality supervision.
