| 摘 要： | 利用中国两次农业普查对农村主要基础设施的调查资料,运用随机前沿生产函数模型研究了公路、码头及铁路三类交通基础设施建设对农业生产技术效率的影响.研究结论表明:水路和公路的普及程度对中国各省区农业生产技术效率的提升有显著的推动作用,铁路运输网对农业生产技术效率的改进效果尚不明显.

| Abstract: | Technical efficiency is an important index of agricultural composite production ability,and it is the core of the growth of agricultural economics.Using data of China’s agricultural census,this study applies a stochastic frontier production model to examine the effects of roads,docks,and railways on agricultural technical efficiency.The results illustrate that the popularity of docks and roads have significant positive effect on efficiency improvement of agricultural production,and the contributions of railways construction on agricultural technical efficiency are not obvious. |
