创新生态系统中多主体知识转移生态关系的建模与实证分析

Model and Empirical Analysis on Ecological Relationship of Multi-agents Knowledge Transfer in Innovation Ecosystem

[目的/意义]创新的成功需要在生态中实现,研究创新生态系统中多主体间知识转移过程中的生态关系有助于促进系统的持续健康发展。[方法/过程]构建多主体知识转移生态关系模型,并以新能源汽车领域的专利授权数据为例,用灰色估计法验证Lotka-Volterra模型的合理性,最后通过仿真实验探讨不同生态关系下多主体知识转移的演化规律。[结果/结论]研究发现,互惠共生的生态关系下高校的引入显著推动主体间的知识转移;偏利共生的生态关系下核心企业更能快速促进卫星企业的知识增长;寄生共生的生态关系下卫星企业阻碍其他主体的良性发展;竞争共存的生态关系下核心企业抑制高校和卫星企业的知识获取。

[Purpose/significance]The success of innovation needs to be realized in the ecology.Studying on the ecological relationship in the process of knowledge transfer among multiple agents in the innovation ecosystem is helpful to promote the sustainable and healthy development of the system.[Method/process]Firstly,this paper established the ecological relationship model of multi-agents knowledge transfer,then,the rationality of Lotka-Volterra model was verified by grey estimation method with patent authorization data of new energy vehicles.Finally,explored the evolution rule of multi-agents knowledge transfer under different ecological relationships through simulation experiments.[Result/conclusion]The results show that:Firstly,introduction of university significantly drive patent creation among entities in mutualistic ecological relationship.Secondly,introduction of university significantly drives knowledge transfer among entities in mutualistic ecological relationship.Secondly,the core enterprise can more quickly promote knowledge growth of satellite enterprise in commensalism ecological relationship.Thirdly,the satellite enterprise hinders the benign development of other subjects in ecological relationship of parasitic coexistence.Fourthly,the core enterprise inhibits the acquisition of knowledge by university and satellite enterprise in ecological relationship of competitive coexistence.
