知识互溢视角下新能源汽车产业链功能演化GERT网络模型研究

新能源汽车产业链具有资金与技术密集、知识自发溢出等特点，其功能提升与发挥程度决定产业发展质量。提升我国新能源汽车产业创新竞争力和整体水平，关键在于促使创新价值增值最大化，充分发挥产业链功能。针对我国新能源汽车产业链发展现状，构建基于创新价值流动的新能源汽车产业链功能演化GERT网络模型，以知识互溢为视角，设计未进行知识互溢、初步知识互溢和充分知识互溢3种仿真情境进行对比分析。结果发现，知识互溢能够显著促进产业链创新价值增值，提高价值转移概率，充分知识互溢对提升原材料、电池、电机等产业链核心环节功能意义重大。因此，相关部门应精准施策，在发展分散式充电桩、增加“三电”环节资金和人才投入等方面采取更加积极的措施。

The Research of GERT Network Model of Functional Evolution of New Energy Automobile Industry Chain from the Perspective of Knowledge Mutual Spillover

The new energy automobile industry chain has the characteristics of capital and technology intensive,and spontaneous spillover of knowledge.The improvement of its function and its degree of play determine the quality of industrial development.To improve the innovation competitiveness and overall level of China's new energy automobile industry,the key is to maximize the value of innovation,fully developing and giving full play to the function of industrial chain.Aiming at the development status of China's new energy automobile industry chain,this paper constructs a GERT network model of functional evolution of new energy automobile industry chain based on innovation value flow.From the perspective of knowledge mutual spillover,three simulation scenarios of "no knowledge mutual spillover","preliminary knowledge mutual spillover" and "full knowledge mutual spillover" are designed and compared.The research shows that knowledge mutual overflow can significantly promote the innovation value added of industrial chain,improve the probability of value transfer.It is of great significance for improving the functions of the raw materials,batteries and motors links.The relevant departments should take more active measures in developing decentralized charging pile and increasing R&D funds and talent input in the links of "three electricity".
