基于粮食生产技术效率的分析

采用非参数法双产出模型,在对经济快速发展时期山东省粮食生产技术效率测度的基础之上,进一步研究耕地利用模式及其区域分异特征。结果表明,鲁西北和鲁西南作为粮食主产区耕地资源趋于集约利用,而鲁东等沿海或发达地区耕地资源则呈粗放型利用。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,实现直补制度的创新,切实激励直接从事粮食生产的农民提高技术效率,进一步加强水利基础设施建设,实现集约利用日趋稀缺的耕地资源,从而确保十二五期间国家粮食安全和提高粮农收益目标的实现。

Empirical analysis based on grain production technical efficiency

On the bases of measuring food production technological efficiency of Shandong Province in the period of rapid economic development,the paper researches land use patterns and its regional characteristics on the methods of non-parametric methods and dual-output model.The purpose of this study was to explore the transition of China’s grain policy and the use of arable land protection policy orientation in the case of Shandong Province as one of state major grain-producing areas.The results indicated that the government departments should further increase the protection of arable land in a timely manner to carry out institutional innovation,encourage farmers through technological progress and reasonable investment to improve land use efficiency and output efficiency,strengthen the agricultural infrastructure construction,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.
