摘要
给出了技术进步对农业生产影响的定量分析模型,并讨论了农业生产过程中弹性系数的分维含义与特征,运用新的弹性系数的计算方法,对固原县粮食生产过程中的弹性系数作了计算、分析.结果表明,技术进步的贡献率在80年代达到90%以上,90年代以后逐步下降,并趋于稳定.表1,参6.
This paper present the quantitative analytical model of the effects of technique development on agricultural production and discusses the fractal meaning and features of the elastic coefficient of the agricultural production process. With a new calculation method, the elastic coefficient of the food production process in Guyuan County is calculated and analyzed. The results indicate that the contribution ratio of the technique development reaches above 90% in the eighties and declines annually and tends stable after nineties.
