上海农业创新网络及其空间结构研究

本文以1988-2015年上海农业技术领域合著论文和共同申请专利的信息为原始数据，分别表征科学知识网络与技术知识网络。运用复杂网络与空间分析方法，基于城市、区域和国家等3个层面，从网络整体结构、关键节点的比较及其空间结构等方面刻画上海农业创新网络的结构及其演变特征。研究发现：上海农业创新网络的演化具有明显的阶段性特征，具有明显的“核心-边缘”结构，地理邻近的重要性尚未减弱；科学网络中研究机构的中心性明显均高于企业，科研院所占据创新网络的核心位置；技术网络的结构较为松散并呈链状结构，处于发展初期。研究结论为创新网络时空演化过程提供新的研究视角，对农业创新系统良性运转和创新节点的培育具有一定借鉴意义。

The Spatial and Structure of Innovation Network of Shanghai Agriculture Industry

Network perspective has already been applied in diverse area comprehensively. However, the innovation network of agriculture might have been neglected. This paper, using co-publication and co-patent in the field of agriculture in Shanghai from 1988 to 2015 as the original data, focuses on understanding the structural and spatial characteristics of the innovation network. There are some conclusions drawn from the research. Firstly，The innovation network obviously has core-periphery paradigm. Secondly， From the spatial characteristics of the network, although other cities like Beijing, having become powerful knowledge pool, the actors still tend to cooperate with the partners which located within Shanghai. Thirdly, the research institutions has become the center of science network, while the structure of technology network is on the initial stage and display as a chain. The results provide a new research perspective on the evolution of innovation network, which has some guided and reference meaning to the agricultural innovation system.
