中国是一个农业大国,又存在水资源严重不足、降水时空分布不均衡、旱涝灾害频繁等顽疾,粮食保障问题一直受到国家的高度重视。国家粮食生产长期持续增长的基础不牢固,区域性、结构性的矛盾逐渐凸显,制约中国粮食生产能力提高的自然资源因素作用也在加强。因此,提高并保护其粮食生产能力,对保证国家粮食安全具有非常重要的意义。本书不同于多数学者以全国范围为基点,而是选择东北区玉米产量居全国第一的吉林省为研究样本,紧紧抓住与粮食增产密切关联的某一要素投入进行深刻剖析,力图量化最优的要素投入量,从而实现既定的粮食生产规模。同时,本书试图从宏、微观层面分析要素投入过程中存在的各种问题,在农民利益为先的原则下明确要素投入主体,构建中国特殊的供给系统,创新投入机制,扭转多年来投入效果不佳的尴尬局面。
