【摘要】：构建超越对数成本函数,估计不同种类农业基础设施投资在粮食生产中对私人投入要素替代程度和成本结构调整的影响,进而测算基础设施的总成本节约效应,并结合WTO贸易规则提出相应的政策建议。涉及的农业基础设施包括电力、道路和改善农田水土条件的基础设施建设。结果表明,基础设施能够降低粮食生产成本,提高产品国际竞争力;总成本节约效应显示基础设施与劳动、物质资本投入呈现替代效应,与资本呈现互补效应;不同种类基础设施对粮食生产的影响不尽相同,农田水利设施、道路建设主要节约劳动与物质资料投入,电力设施主要节约资本投入。应继续加大农业基础设施投资,不同粮食主产区应根据区域内种植结构、基础设施投资存量与基础设施短板有重点地实施投资。
[Abstract]:This paper constructs a logarithmic cost function to estimate the influence of different types of agricultural infrastructure investment on the substitution degree of private input elements and the adjustment of cost structure in grain production, and then calculates the total cost saving effect of infrastructure. And combined with the WTO trade rules to put forward the corresponding policy recommendations. The agricultural infrastructure involved includes electricity, roads and infrastructure to improve land and water conditions. The results show that infrastructure can reduce the cost of grain production and improve the international competitiveness of the products, the total cost saving effect shows that the infrastructure and labor, the physical capital investment presents the substitution effect, and the physical capital investment is complementary to the capital. The effects of different kinds of infrastructure on grain production are different. Irrigation and water conservancy facilities, road construction mainly save labor and material input, and electric power facilities save capital investment. We should continue to increase the investment in agricultural infrastructure, and the different grain producing areas should focus on the investment in the infrastructure investment stock and infrastructure according to the planting structure in the region.
