摘要
以河南省平原地区农业作为多熟制农业的代表,按主要农时阶段用工量供需平衡的原则建立计算模型,研究农业机械化与劳力负担耕地面积间的定量关系。同时,运用比较利益原理分析农民经营土地的愿望,认为种植业从平分土地状态向适度规模专业化经营发展,必然经历一个兼业化的过程,并提出了计算这一过程转变的经济临界值的方法。运用这一理论和方法研究种植业的适度规模经营,探讨其发展的突现性和经营规模的跃进性,从而揭示出我国农业机械化发展在质和量方面的阶段性。
Taking the plain area in Henan Province for example,the calculation model of labouring balance requiring in major farming seasons is developed.The quantitative relation between agricultural mechanization and the size of cultivated land which must be planted by one farmer is also studied.The principle of comparative benefit is used to discuss and analyze the farmer's desire of managing farmland.The planting development has to go through the process from the state of dividing farmland to the state of specialization management.In this course,peasants not only manage their farmland but also hold other posts.It is also stated how to calculate the economic critical value in this course.The suddenness of its development and the leaping forward in the above kind of management scale are pointed out.Therefore, the nature of stages of China's agricultural mechanization development in quality and quantity can be derived.
