【摘要】：近年来中国粮食进口量与产量、库存齐增,进口呈现明显价差推动型特征。以往研究主要关注农业基础设施的产出增长效应,但在当前关税等边境保护水平较低的开放市场中,单位产品生产成本而非产量成为影响贸易的关键。本文构建超越对数成本函数,探寻入世以来中国农业基础设施对粮食生产成本的影响及其路径,通过对全要素生产率增长的分解,实证检验了促进生产率增长是基础设施降低私人粮食成本的重要路径。结果表明:农业基础设施投资存量增加1%,水稻、小麦与玉米的私人生产成本分别下降0.02%、0.05%和0.1%,且节本效应逐年凸显;基础设施分别贡献水稻、小麦、玉米全要素生产率增长的12%,19%和34%,农业基础设施存量在中、西部地区对主粮全要素生产率增长的正向促进效用优于东部地区。
[Abstract]:In recent years, China's grain import volume and output, inventory increase, import shows obvious price differential driving characteristics.Previous studies have focused on the output growth effects of agricultural infrastructure, but in open markets with low border protection, such as tariffs, unit production costs rather than output are key factors affecting trade.This paper constructs a logarithmic cost function to explore the impact of agricultural infrastructure on grain production cost and its path since China's entry into WTO, and through the decomposition of total factor productivity (TFP) growth,Empirical results show that promoting productivity growth is an important path for infrastructure to reduce the cost of private food.The results showed that the private production cost of rice, wheat and maize decreased by 0.02% and 0.1%, respectively, and the cost saving effect was obvious year by year, and the infrastructure contributed to rice, wheat and wheat respectively.The total factor productivity (TFP) of maize increased by 12% and 34%, and the stock of agricultural infrastructure was in the middle, and the positive effect of the western region on the growth of the total factor productivity of main grain was better than that of the eastern region.
