创新扩散网络结构对创新扩散绩效有重要影响。通过设计基于原胞自动机的创新扩散网络仿真模型,模拟不同网络结构的创新扩散过程,依据确定的创新扩散绩效测量指标,分析了创新扩散网络结构参数与创新扩散绩效之间的关系。研究发现,在创新扩散网络中,个体创新信息采纳概率是影响创新扩散速度和规模的最重要因素;创新扩散网络密度越大,创新扩散规模越大,扩散速度越快;初始创新者数量多可以加快创新传播速度,但不能扩大创新扩散规模。
創新擴散網絡結構對創新擴散績效有重要影響。通過設計基于原胞自動機的創新擴散網絡倣真模型,模擬不同網絡結構的創新擴散過程,依據確定的創新擴散績效測量指標,分析瞭創新擴散網絡結構參數與創新擴散績效之間的關繫。研究髮現,在創新擴散網絡中,箇體創新信息採納概率是影響創新擴散速度和規模的最重要因素;創新擴散網絡密度越大,創新擴散規模越大,擴散速度越快;初始創新者數量多可以加快創新傳播速度,但不能擴大創新擴散規模。

Many scholars agree on the importance of the structure of innovation diffusion network for innovation diffusion,the simulation model of innovation diffusion network is designed based on the cellular automaton model,and nine innovation diffusion networks with different structure are formed,the relationship between the structure of innovation diffusion network and the innovation diffusion performance is analyzed with the data generated from the simulation and the defined indicators in measuring the innovation diffusion performance.The result indicate that in the innovation diffusion network,the entity＇s innovation adoption probability,the possibility to adopt an innovation of a potential adopters when they receive innovation information,is the most important factors affects the speed and scale of innovation diffusion.The higher the density of innovation diffusion network is larger,the bigger the scale of innovation diffusion is,and the faster the diffusion is.More initial number of innovators can speed up the spread of innovation,but not increase the scale of innovation diffusion.The conclusion can provide reference for relevant departments to make innovation diffusion strategies.
