摘 要:虽然我国已实现粮食供求的紧平衡,但不断趋紧的国际粮食供应形势警示我们:粮食增产仍然是维护中国粮食安全的必要之举。我国的粮食直接补贴和良种补贴分别从激励资源投入和技术进步两个角度发挥着增产的功能,其中,促进播种面积增加的直接补贴效率显著,促进新技术扩散的良种补贴作用有限,我国粮食增产主要依赖数量型增长路径。然而,受土地资源约束,技术进步将是我国粮食可持续增产的保障。为维护粮食安全,中国需大力提高技术进步型补贴的力度,在新技术推广中完善风险控制机制,拓展技术进步型补贴种类,引导粮食增产从数量型向技术进步型转变。Although remaining a tight equilibrium in grain supply and demand, our country should keep alert under the ever-tense situations of international grain supply and demand—increasing yield a necessary path to China's grain security. Direct subsidy and subsidy of improved variety are playing their role of increasing yield respectively in encouraging resources input and technological progress. Among these subsidies,direct subsidy to grain crop area scores great achievement, while subsidy of improved variety to new technique plays limited role, so the major way to increasing yield relies on quantitative increase. However, restricted by land resources, we have to take technological progress as the guarantee of sustainable increasing yield. China needs to vigorously improve subsidy to technological progress, perfect risk control mechanism during extending the subsidy item, enrich subsidy types of technological progress, and guide increasing yield form quantitative to technological orientation.
