【摘要】 通过对1985~2005年间我国粮食产量的分析,在影响我国粮食产量的诸多原因中选出了6个主要影响因素,通过建立改进的柯布—道格拉斯生产函数模型,计算出各个影响因素对粮食产量的产出弹性,研究了这些影响因素对粮食产量的影响与作用,最后,在此基础上提出了提高我国粮食产量的对策建议。更多还原

【Abstract】 This paper analyzed China’ s grain yield through 1985 to 2005, then selected six main factors that affected the grain yield. An improved Cobb -Douglas production function is setup to calculate output elasticity of each factor that affected the grain yield, then discussed the degree of influence and effect upon the grain yield, the suggestion and countermeasure based on the function and factors is presented lastly.更多还原
