河北省太行山区粮食生产的投入要素分析

援引1998-2006年河北省太行山区粮食生产的投入数据,运用扩展的C-D生产函数,就投入要素对粮食生产的作用进行研究,结果表明:粮食作物播种面积是粮食生产中最主要的投入要素,之后是水和农业机械的投入,而农业劳动力存在着浪费现象。为此,增加粮食产量应主要从稳定粮食作物播种面积,加强水利基础设施建设,提高用水效率,注重小型农业机械的推进,转移农村剩余劳动力入手。

Analyses on the input factor of grain production in Taihang Mountains area of Hebei

Based on input to grain output between 1998 and 2006 in Taihang Mountains area of Hebei Province and C-D production function,this paper empirically analyses the effects of input elements.The estimate result indicates that the grainsown area plays the most important role in influencing grain production,and then the input of water and agricultural machinery,but agricultural labour are wasting.So,grain output can be mostly raised through keeping the grain-sown area,strengthening the infrastructural constructio...
