摘要
运用C-D生产函数对1991-2006年有关蚕茧的数据进行了模拟,模拟结果显示,这16年间促进每亩蚕茧产值提高的主要因素是劳动生产率的提高,资本对产值的弹性系数为1.48,说明现阶段资本投入的增加能大幅度地提高亩产值,而劳动力对产值负的弹性系数表明应进一步降低每亩的用工数量,提高劳动生产率。
This paper simulated the cocoon data from 1991 to 2006 by C-D production function. The results indicated the promotion of labor productivity was the main factor which improved cocoon unit yield during these 16 years. The elasticity value between capital and output was 1.48, which showed the increase of capital investment could improve the cocoon unit yield, while the negative elasticity value between labor and yield indicated that the labor number should be reduced and the labor productivity should be improved.
