农业资源再配置的生产率效应评估

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 lagging behind,while agribusiness resource reallocation has improved; 2)from the perspective of sample distribution,the reallocation of labor factors,land factor and integrated resource is lagging behind in northeast; 3)from the perspective of productivity effect,the optimal reallocation of labor factors can increase labor productivity by 54.64%,the optimal reallocation of land factors can increase land productivity by 55.86%,and resource reallocation contributes 17.37% of total factor productivity growth.Agricultural resource reallocation has a large potential productivity effect.Therefore,more attention should be given to the optimal allocation of agricultural resources in policy formulation,especially for the reallocation of land and labor,so as to make full use of the productivity effect of resource reallocation.
