Capital accumulation and the growth of aggregate agricultural production
实证研究资本积累对农业产出增长的作用，发现农村劳动力是农业GDP和作物生产的主要解释因素，而资本积累主导了畜牧业生产，且资本与土地呈替代关系、与劳动力呈互补关系。
Abstract This report empirically examines the role which capital accumulation plays in the growth of agricultural production potential. The report assumes that the degree to which available technology can be implemented in a nation's agricultural sector depends on accumulated investments that have been made in the sector. Results from estimating aggregate agricultural production functions show the primary importance of rural labor in accounting for agricultural gdp and crop production. Capital accumulation is the dominant explainer of livestock production. Estimation results support the conjecture that capital tends to save scarce land resources (substitute relationship) and use rural labor (complementarity relationship). Output supply elasticities derived from the estimated equations tend to be large. The large elasticities imply that price distortions have had large impacts on resource use and production.
