北京市电动汽车充电设施创新生态系统分析

Analysis on Innovation Ecosystem of Charging Facility for Electric Vehicle in Beijing

将创新生态系统理论与复杂网络理论相结合,建立了城市电动汽车充电设施创新生态系统模型,分析了电动汽车充电设施发展已初具规模的城市之一——北京在2013-2016年的电动汽车充电设施创新生态系统网络。研究发现:网络主体越丰富,充电设施创新生态系统网络的介数越大,网络结构越稳定;政府部门、市内销售企业、充电设施企业、新能源车辆用户以及场地提供方的类型越多,网络的连通度越好,网络越稳定;充电设施创新生态系统网络中各主体包含的分支主体越多,网络越稳定,充电设施利用率越高,网络效能越好。

Combining the theory of innovation ecosystem with the theory of complex network,this paper analyzes the innovation ecosystem network of charging facility for electric vehicle in Beijing from 2013 to 2016. The result shows as follows: the richer the subject in network, the greater the betweenness of network,the more stable the structure of network; the more the government policy,sale enterprises in city, charging facility enterprise, consumer and supplier for place, the better the connectivity of network, the more stable the structure of network;the more the branch of subjects in innovation ecosystem network, the more stable the structure of network,the higher the utilization of charging facility,the better the efficiency.
