摘　　要：知识的网络溢出效应在产业创新发展中的作用日益显著。文章以中国新能源汽车产业的创新活动为研究对象,基于新能源汽车专利数据构建中国新能源汽车产业的城市合作矩阵,并分析了中国新能源汽车产业创新网络的结构及其演化过程。在此基础上,运用空间杜宾模型计算了新能源汽车产业基于创新网络关系的溢出效应,并将结果与基于城市距离关系与邻接关系的溢出效应的结果进行对比。结果表示:(1)中国新能源汽车产业的创新活动已初具规模,并形成了一定规模的创新网络,但城市间、企业间的创新合作关系并不密切;(2)新能源汽车的创新活动主要集中于规模较大的城市中,并且此类城市拥有更强的辐射带动能力;(3)企业的研究与试验发展(R&D)经费投入是推动当地新能源汽车产业创新发展的核心动力,但整体上并未产生显著的溢出效应。The network spillover effect of knowledge has been playing an increasingly significant role in the development of industrial innovation.The urban cooperation matrix of China’s new energy automobile industry is built based on new energy automobile patent data,and the structure and evolution process of China’s new energy automobile industry are depicted.On this basis,the spatial Dubin model(SDM)is used to calculate the network spillover effect,and its results are compared with the results of spillover effect based on the relationship of spatial contiguity and distance of cities.The results show that the innovation activities of China’s new energy automobile industry have begun to take shape,and a certain scale of innovation network has been formed.However,the innovation cooperation among cities and enterprises is not close.The innovation activities of new energy automobile industry are mainly concentrated in large cities,and from such cities,the innovation activities have strongly radiation to surrounding regions.The R&D investment of enterprises plays the key role in promoting the innovation and development of the local new energy automobile industry,but it has not produced significant spillover effect on the countrywide scale.
