英文文献摘要：
This article examines technical efficiency of the Chinese grain sector using the framework of stochastic production frontier. The results reveal that: the marginal products of labor and fertilizer are much smaller than that of land; human capital and farm-level specialization have positive effect on efficiency, land fragmentation is detrimental to efficiency, and elder farmers are as efficient as younger farmers. We also examine the effects of size, mechanization and geographic location. Simulation results show that significant output gains can be obtained by eliminating land fragmentation, improving rural education and promoting specialization and mechanization.

摘要本文利用随机生产前沿面框架，考察了中国粮食部门的技术效率。结果表明:劳动和肥料的边际产量远远小于土地的边际产量;人力资本和农民专业化对效率有正向影响，土地细碎化不利于效率，年长的农民和年轻的农民效率相同。我们还考察了规模、机械化程度和地理位置的影响。模拟结果表明，消除土地细碎化、改善农村教育、促进专业化和机械化可以获得显著的产出收益。
