技术进步与粮食安全

The Progress of Technology and Food Safety

从G函数的范式结构出发,以两部门的价格增长模型耦合耕地数量和粮食需求数量等约束条件,陈述了产品供给、非农业出口和农业进口与耕地、劳动力、资本和粮食需求约束数量的基本结构,表示了贸易市场与这些固定数量之间存在的统一关系。将分析的焦点集中于非农业出口和国内农业供给进步方面,结果表明,粮食安全和耕地保护问题的缓解,主要取决于经济体内生产能力的不断提高,即科技进步。耕地固定数量和粮食需求数量的实际约束作用,将逐步被技术进步所突破。

Starting from the paradigm structure of G function, based on the confined conditions of farmland amount and the amount of de- mand for food which conforms to the price increase model of two Departments, the author expresses the fundamental structure between the product provide, non-agriculture export, agriculture import, farmland, labor, capital and the confined amount of demand for food, and demonstrates the united relationship between trade market and these stable amount. He put the analysis focus on non-agriculture export and domestic agriculture provide, and the result shows that the release of the issue between food safety and farmland protection mainly depends on the continuously increase of the production power in the economy unit, that is ,technology progress. The confining role of the amount of farmland and the amount of demand for food will be decreased by technology progress.
