| 摘 要： | 在构建包含农田水利基础设施投资在内的农业超越对数随机前沿生产函数的基础上,利用随机前沿法测算我国31个省(市、自治区)1996—2015年农业全要素生产率,对测算的结果通过空间计量方法分析农业全要素生产率的空间特征及农田水利投资对其产生的影响。结果表明:我国各省(市、自治区)农业全要素生产率整体增长呈现上升趋势;横向和纵向的分析结果显示其增长具有一定的区域性和地域集聚性;农田水利投资对农业全要素生产率的影响为正,且具有较弱的溢出效应,其中直接效应值为0.2865,间接效应值为0.0574,总效应值为0.3439。

| Abstract: | Based on the establishment of trans-logarithmic production function of agriculture which includes investment in farmland water conservancy, the stochastic frontier approach is used to calculate the total factor productivity of agriculture in 31 provinces(municipalities and autonomous regions)of China from 1996 to 2015. The spatial characteristics of the total factor productivity of agriculture and the influences of investment in farmland water conservancy are analyzed. The results show that the growth of the total factor productivity in China generally has an increasing trend. The horizontal and vertical analyses shows that the growth has regional property and regional agglomeration. The influences of investment in farmland water conservancy infrastructure on the total factor productivity of agriculture are positive, and they have weak spillover effect. Among them, the direct, indirect and total effects are 0. 2865, 0. 0574 and 0. 3439, respectively. |
