          摘要:

          伴隨農業稟賦變化和誘致性技術變遷,農戶對生產要素投入結構作適應性調整,進而影響勞動生產率增長?;跀U展的C-D函數,構建投入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,實證檢驗了要素投入配置變化對我國糧食勞動生產率的影響。研究表明:(1)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玉米勞動生產率的提升。(2)在全國層面,化肥-勞動配比彈性系數顯著為正,作用最明顯;改善種子-勞動配比、機械-勞動配比也可以顯著提升玉米勞動生產率。(3)在產區層面,華北產區的化肥、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。(4)與勞動節約型要素相比,土地節約型要素與勞動配比改善對玉米勞動生產率的影響更為顯著,對全國和產區兩個層面都適用。本文的政策含義在于,應堅定不移地推進勞動力轉移就業,同時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發展。

          Abstract:

          With the change of agricultural endowment and induced technological progress in China, farm household transform inputs structure timely, which affect the growth of labor productivity. This paper constructs elastic coefficient of input factor allocation ratio affecting labor productivity and examines the effect of rural labor transfer on labor productivity of maize, based on the expanded cobb-douglas production function. The results show that: (1) factor allocation structure adjustment enhances maize’s labor productivity because technical equipment allocated to unit labor has been improved significantly, through reducing the labor and increasing fertilizer and machinery. (2) At the national level, the elasticity of fertilizer-labor ratio affecting on maize’s labor productivity is the most significant positive effect, as well as the elasticity of seed-labor ratio and machinery-labor ratio. (3) At the regional level, the elasticity of fertilizer-labor ratio, seed-labor ratio, machinery-labor ratio and pesticide-labor ratio are significantly positive in North China. The elasticity of pesticide-labor ratio is negative in Northeast China and the elasticity of machinery-labor ratio isn’t significant in Southwest China. (4) Compared with labor-saving technology, land-saving technology appears more significant effect on maize’s labor productivity. The policy implication is that improvement the quality of input factors and optimization the structure of factor allocation, as well as continuing to promote rural labor force transfer to nonagricultural sector. Especially, it emphasizes the matching of the inputs factor, the integration of technical equipment and promoting agricultural socialized technical service.
