摘要
基于公共产品模型和成本函数理论,建立最优化条件下的农业生产成本函数模型,以劳动力、固定资本、化肥投入作为农业生产成本的主要组成部分,运用分位数回归方法分析灌溉设施、等外公路对1995-2011年我国省际农业生产成本的影响。结果表明:灌溉设施和等外公路的建设对我国农业生产成本有正向促进作用,农业生产成本对灌溉设施、等外公路的弹性系数均为正;随着农业生产成本的增加,灌溉设施的影响呈增长趋势,而等外公路的影响先增后减。
Based on Public Expenditure Model and cost function theory, this paper first constructs agricultural cost modeling under the optimized condition, then this paper treats inputs of labor, fixed cap- ital and fertilizers as the component of agricultural cost, and uses Quantile Regression to analyze the effect of irrigation facility and substandard highway on China＇s agricultural production cost at provincial level from 1995 to 2011. The result indicates that construction of irrigation facility and substandard highway has the positive effect on China＇s agricultural production cost and elasticity coefficient of agri- cultural production cost is also positive. With the increase of agricultural production cost, the effect of irrigation facility is increasing, but the effect of substandard highway is first increasing and then decrea- sing.
