Abstract：Based on the reconstructed agricultural science and technology index system,the entropy weight TOPSIS method is used to estimate the Chinese agricultural science and technology innovation level.According to the spatial auto-correlation,trend surface and spatial gravity models,its space-time evolution characteristics are analyzed and the influence mechanism is studied with the further application of the GWR model.The results reveal the followings.①China's agricultural science and technology innovation level is relatively low,and the polarization trend and level difference are large.In general,it shows a development trend of hierarchical decrease from Northeast China—North China—East China to southwest China—Northwest China.②Big variation within the region regarding the level of Chinese agricultural science and technology innovation is obvious,showing an inverted ζ-shaped trend for the spatial pattern.Meanwhile,the structure of spatial connection network has been featured by “density in the east and sparseness in the west”,revealing a big spatial connection intensity between the Northeast China and East China,indicating a spatial variation pattern where there's strong spatial triangular connection between Heilongjiang-Zhejiang-Anhui and intense cross connection between Shaanxi-Shandong,Shandong-Hubei and Shaanxi-Zhejiang.③Great positive effect has been made on agricultural science and technology innovation by the level of government support,human capital and internet+ strategy.Also rural economy level and agricultural resources in some regions have exerted a positive influence on agricultural science and technology innovation from the negative.But regional openness has negatively affected agricultural science and technology innovation in most regions.
