山东省小麦生产技术效率变化特征及结构优化

本文基于非参数方法通过构建双产出模型，在对山东省小麦生产技术效率测度的基础上，具体分析其历时特征和小麦生产资源配置结构优化策略。结果表明，山东省小麦生产技术效率1996年以来先是大幅度下降而后缓慢上升，其主要制约因素是规模效率。研究所体现的政策含义是，政府部门在进一步加大对耕地保护的同时，适时进行制度创新，激励粮农通过技术进步和合理的投入，提高耕地利用效率和产出效率，进一步加快农村剩余劳动力转移，加强农业基础设施建设，使转型期中国耕地资源的利用实现从粗放型向集约型转变，从而确保国家粮食安全和粮农收益最大化双重目标的实现。

Study on technical efficiency and strategy for optimizing sturcture of Wheat of Shandong

In order to solve China＇ s grain problem of food security facing the world economic crsis and the decrease in the number of arable land with our urbanization and industrialization, based on the non-parametric method of double-output model, and on the basis of the measurement of grain production technical efficiency, this article specifically researched the wheat production technical efficiency and optimizing the strategies. The researching results showed that the wheat production technical efficiency was declining in the first stage but kept rising in the last stage since 1996, and the wheat production scale efficiencies were among the worst, the results showed that central government should further increase the protection of arable land in a timely manner to carry out institutional innovation, encourage farmers to improve land use efficiency and output efficiency through technical progress and reasonable investment, strengthen the agricultural infrastructure construction, accelerate the transfer speed of surplus agricultural labor, improve the efficiency of land use and production efficiency, so that to realize the changes for China＇s cultivated land resources use from extensive to intensive, in order to ensure the dual objectives for national food security and maximizing the income of farmers in the transition, so that to realize the changes for China＇ s cultivated land resources use from extensive to intensive, in order to ensure the dual objectives for national food security and maximizing the income of farmers in the transition.
