以中国干旱半干旱地区农业技术创新的制高点杨凌农业示范区作为创新扩散源头,以关中地区作为扩散区域,从构建评价指标体系入手,对关中地区各市区农业技术扩散环境进行定量化评价与分析。结果表明:关中地区总体扩散环境欠佳,各市区(除杨凌外)扩散环境差别不大;各个具体的评价因子对各地市扩散总体环境的贡献表现出较大的差异性;关中地区表现为3种不同的扩散环境:杨凌区最优,宝鸡、咸阳、西安市次之,铜川、渭南两市扩散环境最差。

The external environment greatly influences the diffusion of ari-technique innovation.The study on the diffusion environment is helpful to know the factors which affect the diffusion process, so as to find out the effective countermeasures for the diffusion.Yangling National Agriculture High-tech Industries Demonstration Area is a demonstration area of agri-tecnique innovation in arid and semi-arid areas of China, which serves as a source of innovation with its surrounding areas.Taking Guanzhong as its diffusion region, the diffusion environment of agri-technique innovation are analyzed and evaluated based on the quantitative approach.The results show that the overall diffusion environment of Guanzhong is not good except Yangling area.There is little difference among the diffusion environment of each municipal area.The contribution that every factor asserts to the diffusion environment of every area is varies greatly.There are three different types of diffusion environment existing in Guanzhong area, among them, Yangling is the best one, Baoji, Xianyang and Xi’an come next, Tongchuang and Weinan are the worst.The authors also point out the optimizational direction of diffusion environment for Guanzhong area, and pave the way for the theoretical study on diffusion environment.
