农业科技园技术扩散的实证研究——以杨凌示范区为例

农业科技园是我国农业技术创新的重要源头和崭新模式,园区不仅要解决自身发展问题,还肩负着技术扩散和推广的使命.选取国家级杨凌农业高新技术产业示范区为技术创新和扩散源,我国中西部干旱半干旱农区为技术创新扩散区域,在系统调查园区内农业技术创新成果采用情况的基础上,从时间维和空间维角度对园区农业技术扩散轨迹进行实证分析,以期揭示农业技术扩散的时空规律,为政府制定合理的农业技术推广政策提供理论和实践依据.

RESEARCH ON TECHNOLOGICAL DIFFUSION OF AGRICULTURE SCIENCE AND TECHNOLOGY GARDEN: AN EXAMPLE OF YANG -LING DEMONSTRATION ZONE

The agriculture science and technology garden has become important source and new pattern in agricultural technique innovation in our country,it not only need resolve itself's developing problem,but also takes on the missions of technology diffusion and extension.In order to research on technology diffusion of agriculture science and technology garden from time and space characteristics,Yang-ling demonstration zone was chose as the sources of innovation and diffusion,and agricultural districts of Arid and Semi-Arid area of northwest of China was chose as diffusion region.Based on system investigation on technology of agriculture science and technology garden,temporal and spatial law of agriculture technology diffusion was summarized,which provides theoretical and practical foundation in making effective spread policy of agricultural technology.
