摘要：

根据我国粮食主产区11个省1990~2004年地均种植业产值、地均劳动力及各种农业生产物质的投入情况，以耕地产出效率为主要研究对象，运用随机前沿生产函数方法计算出各省历年来的耕地产出效率值。研究表明：现阶段我国耕地经营仍以人力与物质成本的投入为主。与机械化生产相比，化肥等化学和人力密集型的生产方式更能与小规模农户经营的体制相适应；我国耕地产出效率的整体水平不高，耕地的实际产出与现有投入水平下的潜在产出之间存在较大差距；省际间耕地产出效率与经济发展水平没有必然联系，且其差距有着缩小的趋势；近15年来，我国耕地产出效率虽然逐渐提高，但提高的速率却在下降。表明我国现阶段的农业高产需要依靠大量物质投入来维持，生产成本越来越高，继续增加物质上的投入对耕地产出效率的提高意义不大。因此，充分、合理地利用现有资源和技术条件，依靠生物技术的进步，即作物品种的改良来提高耕地的产出，是提高我国耕地产出效率、增加农民收入的重要途径。

Abstract:

Based on the productive value of crop cultivation and agricultural means of production input data per kilo ha of 11 provinces in main food producing area of China,the treated arable land production efficiency was investigated,and production efficiency value of arable land in each province per year was also calculated using stochastic frontier production function method.It is shown that in the current period,labour and material cost's input dominate the production mode in arable land production.Compared with mechanization production mode,fertilizer and labour intensive production mode is more adapted with small scale farmer household production.There are great differences between the actual output of arable land and potential output under present input level.Arable land production efficiency has no obvious relation with economic development level and interprovincials gap reduced continuously.Over the last 15 years,production efficiency of arable land improved,but its speed slowed down gradually,indicating that maintenance of high agricultural yield required plentiful material input.The cost of production is getting higher and higher.Continued increase in material input has little significant effect on the improvement of production efficiency of arable land.So,to make the best use of existing resources and technical conditions,and to rely on biotechnological advancement,that is to depend on crop varietys betterment to improve the output of arable land should be the major path to improve arable land production efficiency and increase farmers，income in our country.

Key words: Chinas main food producing area, arable lands production efficiency, stochastic frontier production function
