我国农业部门资本投入对粮食生产技术效率的影响研究--基于空间计量经济面板模型的实证

摘要

The technical efficiency of China's grain production among regions was significantly different.The northeast, north,south and the Yangtze River regions were showing higher level,while the northwest,southwest and south were in lower level.This paper selected grain production and agriculture sector capital investment panel data from 30 provinces from the year of 2001 to 201 1 to research the spatial location heterogeneity,the degree of spillover and diffusion level between technical efficiency of China's grain production and the agricultural sector capital investment.The results showed that the technical efficiency of China's grain had obvious spatial concentration;capital investment had significantly influence on technical efficiency space diffusion;with spillover of capital and technology,the imbalance in food industry will become in-creasingly serious.As to this issue,it should focus on strengthening agricultural capital investment in northwest,central and southwestern regions to accelerate the pace of development of agricultural technology.%我国粮食生产技术效率的地区间差异显著。选取我国30个省（区、市）2001—2012年的粮食生产与农业部门资本投入面板数据，研究我国粮食生产技术效率与农业部门资本投入的空间区位异质性、外溢性和扩散程度。研究结果表明，我国粮食技术效率具有明显的空间集聚，并且农业部门资本投入对技术效率的空间扩散影响显著。针对该问题要着力加强西。
