中文摘要:
      基于对甘肃、重庆和广东3省(市)3个山区马铃薯主产县453个马铃薯种植农户的实地调研数据,运用超越对数随机前沿模型测算我国山地地区不同规模农户马铃薯生产技术效率,并采用Tobit模型探究农户马铃薯生产技术效率的影响因素。结果表明:我国山地地区农户马铃薯生产技术效率较低,若消除技术无效率项,产出仍有31.6%的提升空间;农户马铃薯种植大、中、小三种规模类型中,中等规模农户马铃薯生产技术效率最高,小规模次之,大规模最低;土地块均面积、劳动力数量、农户专业化程度、参加合作社以及农户认知水平等因素对马铃薯生产技术效率有正向影响,土地规模对生产技术效率有负向影响。从政府、新型经营主体和农户等层面提出相关对策建议,以提升山地地区马铃薯生产技术效率,促进小农户与现代农业发展有机衔接。
英文摘要:
      Based on the field survey of 453 samples of potato farmers in three mountainous area in Gansu,Chongqing and Guangdong,this paper calculates the technical efficiency of potato production farmers in different scales in typical mountainous areas with the employment of transcendental logarithmic SFA model.Furthermore,a Tobit model is also applied here to explore the potential factors influencing the potato technical efficiency.The results indicate that:(1) The potato technical efficiency in China is at a lower level as a whole,which still leaves a possibility of 31.6% to increase.(2) Among the three scales (namely large,medium and small) of potato planting,the highest level of potato technical efficiency occurs at medium scale,closely followed by the small scale and the large scale.(3) Land fragmentation,labor forces,the degree of specialization of famers,participation in cooperatives and cognitive level positively influence the potato technical efficiency,while land scale shows a negative effect.Thus,countermeasures are proposed from three perspectives,namely local government,new-type manager and potato farmer to promote the potato technical efficiency in mountainous areas,and to facilitate the organic linking between the developments of small farmers and modern agriculture.
