【摘要】：我国玉米种植范围辽阔,地区差异较大,针对不同地区进行玉米生产调整对实现玉米供给侧结构性改革的目标意义重大。本文通过对我国31个省(市、区)的玉米供需结构和消费用途进行比较,并运用DEA模型对我国20个省(市、区)的玉米生产效率进行评价。结果显示,我国玉米存在供需的区域性差异,主要生产区域与消费区域错配;山西、黑龙江、江苏、安徽、山东、河南、重庆、陕西、新疆的玉米生产投入结构和产出结构配置合理,吉林、辽宁省的玉米生产综合效率有待提高。本文提出我国玉米供给侧结构性改革中应考虑各个地区的供需结构;稳定生产效率高的地区玉米产量,调减生产效率低且需求量少的地区玉米产量;依靠科技力量提高玉米生产效率,降低生产成本。
[Abstract]:China has a vast range of maize planting and great regional differences. It is of great significance to carry out corn production adjustment in different regions to achieve the goal of corn supply-side structural reform. This paper compares the supply and demand structure and consumption use of maize in 31 provinces (cities and districts) in China, and evaluates the maize production efficiency of 20 provinces (municipalities and districts) by using DEA model. The results showed that there were regional differences between supply and demand of maize in China. In Shanxi, Heilongjiang, Jiangsu, Anhui, Shandong, Henan, Chongqing, Shaanxi, Xinjiang, maize production input structure and output structure allocation is reasonable, Jilin, Liaoning Province maize production efficiency needs to be improved. In the structural reform of the supply side of maize in China, the supply and demand structure of each region should be considered, the yield of maize in the region with high production efficiency should be stabilized, and the yield of maize in the region with low production efficiency and low demand should be reduced. Rely on scientific and technological forces to improve maize production efficiency, reduce production costs.
