【摘要】 本文运用定性与定量分析相结合的方法,对1975—1982年扬州地区的主要农产品成本进行了系统的分析。扬州地区农产品成本变功分为低成本、成本急剧上升和成本大幅度下降三个阶段,并深入分析了成本各因素的变化及其作用。通过经济计量分析可以看到,在扬州地区现有施肥水平下,每增施一元钱的化肥和自然肥料,可分别使当年麦子增产7斤多和5斤多。 最后,本文就扬州地区如何降低成本提出了一系列的建议。更多还原

【Abstract】 The systematic analysis on the costs of the main agricultural products in Yangzhou area, Jiangsu Province during 1975—1982 is made by a method of combining qualitative analysis with quantitative analysis.The changes of the costs of the main agricultural products are derided into three stages, the low cost period, the cost rapidly increasing period and the cost greatly decreasing period. And the penetrative study is carried out on the variation and function of each factor of agricultural product costs.Through the analysis of econometrics, it is shown that under the present fertilizing standard, 7 jin (catty) wheat can be increased by using one yuan’s worth of chemical fertilizer and 5 jin (catty) wheat or 0.4 jin (catty) cotten can be increased by using one yuan’s worth of manure.Finally, a series of proposals to decrease the agricultural product costs are suggested.更多还原
