          摘要:

          優化農業資源配置對促進農業生產率增長具有重要作用。以勞動生產率、土地生產率和全要素生產率為例,基于2002-2015年1384個縣的面板數據,通過OP協方差分解考察了農業資源再配置及其對農業生產率的影響。研究發現:①分要素來看,勞動要素再配置和土地要素再配置均較為滯后,農業綜合資源再配置則有所改善;②分地區來看,與東部、中部和西部地區相比,東北地區的勞動要素再配置、土地要素再配置和綜合資源再配置均較為滯后;③從生產率效應來看,勞動要素的最優再配置可提升54.64%的勞動生產率,土地要素的最優再配置可提升55.86%的土地生產率,資源再配置貢獻了17.37%的全要素生產率增長。農業資源再配置具有較大的潛在生產率效應。為此,應在政策制定上給予農業資源優化配置更多關注,重點推進農業土地和勞動要素的優化配置,充分發揮農業資源再配置對生產率增長的驅動作用。

          Abstract:

          Optimizing the allocation of agricultural resources plays an important role in promoting the growth of agricultural productivity. Based on 1384 county-level panel data from 2002 to 2015, this paper estimates the resource reallocation and its productivity contribution by OP decomposition taking labor productivity, land productivity and total factor productivity as examples. The results show that;① Overall, the reallocation of land factors and labor factors are both relatively lagging, and the comprehensive resource reallocation is continuously optimized. ② From the perspective of sample distribution, the efficient reallocation of labor, land and total factors in northeast region is relatively lagging. ③ From the perspective of productivity effect, the optimal reallocation of labor factors can increase labor productivity by 54.64%, and the optimal reallocation of land factors can increase land productivity by 55.86%, and resource reallocation contributes 17.37% of total factor productivity growth. The resource reallocation has a large potential productivity effect. Therefore, the resource reallocation should gain more attention when putting forward agricultural policy, especially for the reallocation of land and labor, to make full use of the productivity effect of resource reallocation.
