摘　　要：以农业科研机构R&D资金投入为研究对象,在探讨基础研究、应用研究与试验发展三类型农业R&D投入空间分布特征的基础上,利用核密度函数系统分析2002—2013年不同类型农业R&D投入分布的动态演变,并构建计量经济模型研究其影响因素。结果表明:1农业R&D基础研究和应用研究投入变化相对平稳,而试验发展投入则表现为持续上升趋势;2三类型农业R&D投入分布格局转变较大,均呈现出明显的区域差异;3应用研究和试验发展投入区域差异显著扩大,而基础研究投入差异则经历先缩小再扩大的过程,总体呈小幅增大趋势;4基础研究和应用研究投入受到科研机构数量的影响较大,试验发展投入更易受到社会经济因素的影响,农业科技政策对农业R&D投入增长的促进效果由试验发展向基础研究增强。Based on spatial distribution feature of three kinds of agricultural research and development inputs （ basic research, applied research and experimental development research） , this study took agricultural research and development inputs in agricultural scientific research institution as research objects, analyzing their dynamic evolution from 2002 to 2013 by using kernel density estimation method exploring the driving forces by constructing economic model. Results showed that ： （1）Basic research and applied research inputs changed relatively stable, while experimental development research inputs showed a continuous rising trend. （2）Distribution pattern three kinds of agricultural research and development inputs showed a big shift, presenting obvious regional difference. （3）Regional difference of applied research and experimental development research inputs expanded significantly, while regional difference of basic research inputs showed a slight increasing trend in total, going through a process from narrow to expand. （4）The basic research and applied research inputs were affected significantly by quantity of research institutions, while experimental development research inputs was influenced by socio-eco- nomic factors. The promotion effect of agricultural science and technology policy to agricultural research and development inputs was en- hanced from experimental development research to basic research.
