Agricultural Technology Progress and Spatial Diffusion in Counties in Fujian——An Analysis Based on Spatial Econometrics
-
摘要: 利用2001~2010年福建省县域数据,构建包含非农部门技术扩散的农业技术进步模型,并利用空间面板数据对福建省县域农业技术进步进行实证分析。结果显示:福建省县域农业技术具有明显的空间相关性,并随着农业技术资本的积累而呈现逐渐减弱的趋势;非农部门技术进步、农业技术资本投资以及县域间农业技术扩散,是提升农业技术进步的主要途径;技术资本投资影响农业部门对非农部门技术扩散的吸收能力,也是农业技术在县域空间上扩散的主要媒介。因此,加强农业技术资本积累是促进农业技术进步的重要保证。Abstract: Using the data collected from the counties in Fujian during 2001-2010,a model on the agricultural technology progress,including the technology diffusion of non-agricultural sector,was constructed.The article also empirically analyzes the model based on the spatial econometrics.The result showed that the technological progress on the county level had a significant spatial correlation.However,the trend was weakened with accumulation of technology capital.Technological progress in the non-agriculture sector,investment of technology capital for agriculture,and agricultural technology diffusion in counties were major paths for the progress.Technology capital affected the capacity of non-agricultural technology diffusion to the agriculture sector,and was the major medium for the agricultural technology to spread to counties.Therefore,to encourage accumulation of technology capital was believed to be critical for the agricultural technology progress on the county level.
