摘要
农业创新知识扩散是实现农业现代化发展的重要一环。现行市场竞争范式下,创新活动已进入生态系统3.0阶段,农业创新也不例外,各类异质资源主体在创新活动的全过程中扮演不同角色以形成物种间的创新生态系统,其网络桥接则形成创新生态网络关系。文章基于创新扩散、复杂网络及传播动力学理论,通过深入分析农业创新生态网络的结构特征,构建创新知识的SIR模型模拟其传播过程,得到影响扩散的变量结果,并选取旬邑县温氏养猪模式推广的案例进行分析,最后结合模型推导结果和知识扩散应用现实,提出聚焦服务主体促进知识扩散的助力作用、立足示范性主体多重乡土网络嵌入关系促成中心型知识扩散、完善利益联结机制以促成知识强关系扩散等促进农业创新知识扩散的建议,以期为实现农业现代化转型提供助力。
The diffusion of agricultural innovation knowledge is an important part of agricultural modernization.Under the current market competition paradigm,innovation activities,including agricultural innovation,have entered the stage of ecosystem 3.0.Various heterogeneous resource subjects play different roles in the whole process of innovation activities to form the innovation ecosystem among species,and their network bridging forms the innovation ecological network.Based on the theories of innovation diffusion,complex network,and propagation dynamics,we analyzed the structural characteristics of the agricultural innovation ecological network in depth,built a SIR Model of innovation knowledge to simulate its propagation process,and got the variable results affecting diffusion.Moreover,a case study of the promotion of the pig farming model of Wen's in Xunyi County was selected for analysis.Finally,based on the results of model derivation and the practical application of knowledge diffusion,some suggestions were put forward to promote the diffusion of agricultural innovation knowledge,which will help to realize the transformation of agricultural modernization.
