当前国内外粮食供求形势在不断变化,为保障国家粮食安全,中国政府及相关部门提出研究构建国家粮食安全新战略体系。在此背景下,对中国玉米生产、消费、进出口的影响因素进行定量分析,通过构建市场均衡模型,对中国玉米供求平衡的变化与趋势进行预测分析。模型研究结果显示,对于玉米供给而言,到2025年中国玉米产量还有7.9%的上升空间,种植面积对于玉米价格的反应较为滞后,而农业补贴政策对于农民种植意愿的提高具有较为显著的效果;增强玉米生产科技要素的投入及提高抗击自然灾害的能力,有利于玉米单产水平的提高。对于玉米需求而言,到2025年中国玉米消费量将要增长38%,玉米饲用需求量和工业需求量呈刚性增长;由于玉米消费量增长速度高于生产量的增长,未来中国玉米产需缺口将会越来越大,玉米供求形势不容乐观。在此基础上,提出了立足国内生产、加大对农业四项补贴的投入力度、充分利用国际市场资源、科学调控玉米深加工等政策建议。
噹前國內外糧食供求形勢在不斷變化,為保障國傢糧食安全,中國政府及相關部門提齣研究構建國傢糧食安全新戰略體繫。在此揹景下,對中國玉米生產、消費、進齣口的影響因素進行定量分析,通過構建市場均衡模型,對中國玉米供求平衡的變化與趨勢進行預測分析。模型研究結果顯示,對于玉米供給而言,到2025年中國玉米產量還有7.9%的上升空間,種植麵積對于玉米價格的反應較為滯後,而農業補貼政策對于農民種植意願的提高具有較為顯著的效果;增彊玉米生產科技要素的投入及提高抗擊自然災害的能力,有利于玉米單產水平的提高。對于玉米需求而言,到2025年中國玉米消費量將要增長38%,玉米飼用需求量和工業需求量呈剛性增長;由于玉米消費量增長速度高于生產量的增長,未來中國玉米產需缺口將會越來越大,玉米供求形勢不容樂觀。在此基礎上,提齣瞭立足國內生產、加大對農業四項補貼的投入力度、充分利用國際市場資源、科學調控玉米深加工等政策建議。

The situation of the food ’ supply and demand has been changing at home and abroad recently .In order to guarantee the national food safety , Chinese government and the relevant departmentsproposed to study and constructa new strategic system of national food safety .In this context , this paper did a quantitative analysis on the influencing factors of Chinese corn production , consumption , import and export.Based on the model of market e-quilibrium , it predicted and analyzed the changes and trend of Chinese corn supply and demand .The model result revealed the facts that , as for corn supply , there will be 7.9%of increase potential for Chinese corn production till 2025.In addition, the impact of corn price on the planting area has a comparative lag , while the agricultural subsidy has significant effect on the planting willingness of farmers;it can improve the unit production of corns increas-ing the input of corn production science and technology and enhancing the capacity against the natural disaster .As for corn demand , the consumption of Chinese corn will increase 38%till 2025 , and the demand of corn used for feeding and industry has been rigidly growing .For the increase speed of corn consumption is higher than that of production, the gap between production and consumption in the future will grow larger and larger .Thus, the trend of corn supply and demand in the future will not be optimistic .Based on this context , it offered some policy sugges-tions that taking national production as a base , reinforcing the input of four major agricultural subsidies , fully taking use of international market resource , scientifically adjusting further processing of corn , etc.
