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.
