摘要
以我国 1 985和 2 0 0 0年的油菜、大豆和花生的成本收益数据为资料 ,分析了 3种油料作物的成本效益及其影响因素。结果表明 :从 1 985年到 2 0 0 0年 ,3种油料作物的成本的年递增率均超过 1 0 % ,超过各自产值的年递增率 ,致使 3种作物的纯收益呈下降趋势 ,3种作物成本的增加是由于生产资料和劳动力价格的上涨所致 ;2 0 0 0年 3种油料作物中花生因其单产和价格高而效益最好 ,油菜尽管单产较高 ,但由于其价格较低、生产成本高而效益最差 ,大豆尽管生产成本低 ,但由于单产低而效益较差。要提高油料作物的效益 ,油菜关键是要降低生产成本尤其是通过推广省工栽培技术降低活劳动成本 ,大豆则主要是提高单产。
Based on the data of cost profits of rape, soybean and peanut in the years of 1985 and 2000 in China, this paper analyzes the cost benefits and their influencing factors of three oil crops. The result shows that the annual growth rate of the costs for the three oil crops exceeds 10% from 1985 to 2000 which exceeds the annual growth rates of the output values of the three oil crops respectively. This causes the declining tendency of the net profits of the three oil crops. The increase of production cost of the three oil crops is due to the rise of means of production and labor cost. In 2000, among the three oil crops, peanut gained the highest benefits because of its high per unit area yield and price, while, because of its low price and high cost of production, rape gained the lowest benefits in spite of its high per unit area yield and soybean gained lower benefits because of its low per unit area yield despite its low cost of production. In order to increase the benefits of oil crops, it’s critical for rape to reduce the cost of production,especially through spreading labor-saving cultivation techniques to reduce labor cost. For soybean, the key point is to increase its per unit area yield.
