中文摘要：

产业集群内企业之间相互临近在增加交流与学习机会的同时,也增加了创新的竞争压力,而这两方面的因素都能在一定程度上促进创新行为的发生。在对创新扩散内在机理加以分析的基础上,从知识和信息的交流与学习角度,构建了创新在产业集群内竞争扩散的模型,分析了模型的平衡点及其稳定性,并从模型的经济意义出发,探讨了创新在集群内扩散的影响因素。分析发现,产业集群内的创新扩散与创新之间的竞争具有正反馈关系,企业的学习能力对创新扩散的速度具有显著影响。模型可用于探究当产业集群内存在两种相互替代的创新时的竞争扩散程度,为企业创新决策提供参考依据,同时,数值计算验证了理论研究结果,增强了模型的应用价值。

英文摘要：

In industrial clusters,mutual communication and learning between enterprises have increased because of geographic proximity,while for the same reason,competition in innovation has been enhanced.Both these factors are propitious to innovate.In this paper,we constructed a competitive diffusion model of innovation from the communicated and learned points of view based on the inherent mechanism analysis of innovation diffusion.Then,we analyzed the balances and their stability of the model.Based on the model,we explored the influencing factors of innovation diffusion which proceed from the model＇s economic significance.Our analysis shows the competitiveness between innovations has significant influence on innovation diffusion,and the learning ability of enterprises exerts significant influence on speed of innovation diffusion.The model can be used for inquiring the innovation competitive diffusion when the industry cluster exist two kinds of innovations which can be substitute for each other,and providing a reference for the choice of enterprise.At the same time,the digital computation increased the understanding and application of theoretical research.
