摘要
通过建立C-D型生产函数,研究了贵州粮食生产的决定因素,发现土地投入、劳动力投入机械总动力投入足以解释贵州粮食产量的95%,并且3种要素投入均是缺乏弹性,且对贵州粮食生产的作用依次递减。3种要素对贵州粮食生产具有规模报酬递增的特点。
C-D production function was constructed to study the decision factors of grain production in Guizhou,it was found out that the land input,labor input and total machinery power input could explain 95% of the grain yield in Guizhou,and all the three factors were inelastic and exerted decreasing effect on the grain production in Guizhou Province.The returns to scale of three factors to Guizhou grain production shoroed decreasing features.
