| 摘 要： | 基于CES生产函数,利用我国1978-2008年的统计数据,实证分析了粮食生产中农业机械总动力与劳动力投入之间的关系。结果表明:单位播种面积农业机械总动力与劳动力投入之间确实具有一定的替代关系,但目前农业劳动力投入量依然是影响我国粮食生产产量的重要因素,而农业机械替代劳动的作用不大。

| Abstract: | The relation between rural labor and agro-mechanism in grain production in China from 1978 to 2008 is analyzed with CES production function Statistical data.Empirical results show that there is an elasticity of substitution rural labor per sowing area and agro-mechanism in grain production.But the rural labor is still an important factor in grain production,and the replacement effect of agro-mechanism for rural labor is inconspicuous. |

| Keywords: | agro-mechanism rural labor replacement effect CES production function |
