基于超效率Output-DEA模型的主产区粮食生产能力评价

Evaluation on the Grain Production Capacity of Major Grain Production Area Based on Super-efficiency Output-DEA Model

应用超效率Output-DEA模型,对我国2008年13个粮食主产省区的粮食生产能力进行了研究。结果表明,主产区处于技术有效的省份仅有4个,其超效率值存在较大差距。多数省区技术无效率是规模效率低造成的。如果能够提高无效率省区的技术效率,发挥有效率省份的生产潜力,对提升全国的粮食生产能力将产生十分明显的效果。各无效率省区还存在投入的冗余,减少这些投入冗余对于降低粮食生产成本具有重要作用。我国政府应该把提高粮食生产效率作为粮食政策的首要目标,促进粮食生产区域的合理布局,优化粮食生产支持政策。

In this article the grain production capacity of 13 major grain production provinces is evaluated based on super-efficiency Output-DEA model.The result suggests that only 4 provinces are efficient and their super-efficiency values are different.Most provinces are inefficient due to the lower scale efficiency.If the technical efficiency of inefficient provinces can be enhanced and the production potential can be explored,China＇s grain production capacity will be improved greatly.Most inefficient provinces have an input slack,the elimination of which will play an important role in saving production cost.The government should set a premier goal of improving grain production efficiency,design a reasonable layout of grain production area,and improve the grain production supporting policy.
