摘要
通过对1986-2005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,建立了改进的柯布-道格拉斯生产函数模型,通过计算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.
Through the analysis of Chinag grain yield from the year 1986 to 2005, selected six factors mainly affecting grain yield, established an improved Cobb-Douglas production function, then calculated output elasticity of each factor that affected the grain yield, discussed the degree of influence and effect upon the grain yield, the suggestion and countermeasure based on the function and factors is presented lastly.
