| 摘 要： | 研究基于影响大豆产出增长的三大因素—种植面积、资本投入、劳动用工,运用柯布—道格拉斯生产函数模型分别测算了三大要素在中国大豆生产中的生产弹性及对大豆产出增长的贡献率。研究结果表明,1991─2008年,种植面积对中国大豆产出增长的贡献率最大,其次是资本投入,而劳动用工的贡献率为负。

| Abstract: | Based on the three factors that affecting the growth of soybean output,namely planting area,capital investment and labor,estimating the production flexibility of the factors and the contribution to the growth of soybean output with using the C-D model.The results showed that planting area was the biggest factor that contribution to the growth of soybean output in China from 1991 to 2008,then was the capital investment,and the contribution of labor was negative. |
