    摘要:

    伴隨著要素稟賦變化和誘致性農業技術變遷,農戶對生產要素投入結構做出適應性調整,進而影響農業勞動生產率增長?;跀U展的Cobb-Douglas函數,構建要素配置比例對勞動生產率影響的彈性系數,并以玉米為例實證檢驗了要素配置比例變化對我國糧食勞動生產率的影響。研究表明:減少勞動投入,增加化肥、機械等投入,配置在單位勞動上的物質技術裝備得到明顯改善,要素配置比例調整有效促進了玉米勞動生產率的提升。在全國層面,化肥-勞動配比彈性系數顯著為正,對玉米勞動生產率的促進作用最為顯著;改善種子-勞動配比、機械-勞動配比也可以提升玉米勞動生產率。在產區層面,華北產區化肥、種子、機械、農藥四種要素與勞動的配比彈性系數都顯著為正;東北產區農藥-勞動配比彈性系數為負;西南產區機械-勞動配比影響不顯著。與勞動節約型要素相比,土地節約型要素與勞動配比的改善對玉米勞動生產率的影響更為顯著,這對全國和產區兩個層面都適用。據此建議:一方面應堅定不移地推進勞動力轉移就業,另一方面要提升農業要素質量和利用效率,優化要素配置結構,尤其要注重要素之間的匹配、技術裝備的集成和農業社會化服務的發展。

    Abstract:

    With the change of agricultural endowment and induced technological progress in China,farm households transform inputs structure accordingly,which contributes to the growth of labor productivity.This paper constructs elastic coefficient of input factor allocation ratio affecting labor productivity and examines the effect of factor allocation ratio change on labor productivity of crops with maize as the example based on the expanded cobb-douglas production function.The results show that:factor allocation structure adjustment enhances maize’s labor productivity because technical equipment allocated to unit labor has been improved significantly through increasing the use of fertilizer and machinery and reducing the labor.At the national level,the elasticity coefficient of fertilizer-labor ratio is significantly positive having most remarkable effect on maize’s labor productivity which can also be improved by increasing the seed-labor ratio and machinery-labor ratio.At the provincial level,the elasticity coefficient of fertilizer-labor ratio,seed-labor ratio,machinery-labor ratio and pesticide-labor ratio are significantly positive in North China.The elasticity coefficient of pesticide-labor ratio is negative in Northeast China and the elasticity coefficient of machinery-labor ratio isn’t significant in Southwest China.Compared with labor-saving factor,land-saving factor has more significant effect on maize’s labor productivity,which applies to both national and provincial level.The policy implication is that on the one hand we should unswervingly promote the transfer of labor force employment,on the other hand,we should improve the quality and utilization efficiency of input factors and optimize the structure of factor allocation,especially pay attention to the matching of the inputs factor,the integration of technical equipment and the development of agricultural socialized services.
