西部地区种植型马铃薯专业合作社技术效率研究
Study on Technical Efficiency of Potato Planting Cooperatives in Western Areas

马铃薯是我国第四大粮食作物和重要的扶贫增收作物，种植型合作社是马铃薯生产的重要组织形式之一。为了研究马铃薯合作社发展状况，探索马铃薯合作社未来的发展方向，采用实地调研数据，运用随机前沿面超越生产函数，对西部地区种植型马铃薯合作社运行技术效率进行了测算。结果表明：西部地区种植型马铃薯专业合作社技术效率提升潜力较大，可控要素：运营时间、专家指导、股份差异程度、自然禀赋、合作社经营范围、管理层是否有激励措施等，对合作社效率损失具有显著的影响。建议通过减少常规投入费用成本以及服务土地面积等方式来改进资源的投入配置，同时有效控制六大要素提升马铃薯合作社的可持续发展能力和服务。
Potato is the fourth largest grain crop of China and important crop for poverty alleviation and planting-cooperative is an important pattern of potato production. In order to study the development situation and ascertain the future development direction of potato cooperatives, this paper, based on field survey data, uses stochastic frontier analysis of production function to estimate technical efficiency of planting potato cooperatives in the western areas .The result shows that the western planting-potato-cooperatives have great potential for the improvement of technical efficiency, controllable elements such as service time, expert guidance ,difference degree in shares, natural talent, business scope of cooperatives and incentive method for management have significant impact on efficiency losses of cooperatives.Therefore, this paper proposes that it is quite significant that general investment cost and land size should be reduced to improve the investment allocation of resources and at the same time, six elements should be effectively controlled to enhance the sustainable development and efficiency for potato cooperatives.
