摘  要:
应用C-D生产函数对1995-2008年聊城市的农业生产投入要素进行了测度与评价。结果表明,聊城市农业生产处于规模报酬递增阶段,各要素的作用比较协调,处于稳步增长阶段;耗电量、化肥施用量、灌溉量对农业产出的增长作用分别为7.74%、4.65%和3.29%;耗电量和化肥施用量的弹性系数都远小于1,说明在目前情况下尚没有充分发挥其投资效益,仍有潜力可挖;影响农业总产出的因素除了已选择的耗电量、化肥施用量、灌溉量3要素外,还有技术水平的提高和政策因素的影响。

摘  要:
Agricultural production factors in Liaocheng city from 1995 to 2008 were measured using C-D production function.The results showed that Liaocheng agricultural production was in a stage of increasing returns and each element was harmonious,in a steady growth stage.Effects of electric energy,chemical fertilizer application,irrigation on agricultural output growth were 7.74%,4.65% and 3.29% respectively.Elasticity coefficients of electric energy and fertilizer consumption were less than 1,which indicated that they had not given full play to their investment returns,and still had the potential to be excavated.Besides the power,amount of chemical fertilizer and irrigation,factors affecting total agricultural output included the advance of technology level and policy.
