摘　　要：随着知识经济的发展和创新驱动发展战略的实施,创新网络及其多维邻近性机制已成为政府和学者共同关注的焦点。利用Ucinet软件,从区域、主体性质等维度,刻画了2009—2014年产业快速发展时期的中国新能源汽车专利创新网络特征。运用PLS-SEM模型,探究全国及不同区域创新网络的多维邻近性影响过程及原因。研究发现:①与中国新能源汽车产业创新活动集中在大城市和三大城市群不同,其合作创新网络主要集聚在京津冀与长三角地区,珠三角地区的创新网络明显较弱。同时,创新能力欠发达的区域出现了与其数量不匹配的合作创新规模。②总的来看,全国创新网络呈现“核心-边缘”结构,国家电网是网络中最重要的创新主体。在京津冀,大型国企集团控制网络,“核心-边缘”结构突出,合作创新最活跃,网络外向程度高。在长三角,区域内主体类型混合多样,“核心-边缘”结构突出,合作创新活跃,网络外向程度较高。在珠三角,民营企业是网络的主要主体,区域网络结构松散,合作创新活跃度低,网络外向程度高。③从创新网络的多维邻近性成因看,在全国尺度,组织关系与知识搜寻是全国网络形成的两大动力。在京津冀,国电集团强有力推动跨区域网络形成。在长三角,国电系及区域大企业影响网络形成,丰富的知识源推动合作创新发生。在珠三角,地理邻近性对民营企业合作创新影响有限,知识需求推动了跨区域合作。In the context of the knowledge-based economy and innovation-driven development strategy,innovation networks and their multidimensional proximity mechanisms have attracted increasing attention from governments and economic geographers.However,knowledge about their regional differences remains limited.Using Ucinet software,the authors describe the technological innovation network characteristics of the new energy vehicle(NEV)industry in China from 2009 to 2014,which corresponds to the period of rapid development of vehicle ownership.The authors use partial least squares structure equation modelling to explore the impacts of multidimensional proximities from national and regional perspectives.The study found that:(1)Unlike innovation,activities are primarily concentrated in metropolitan areas and three major urban agglomerations.The innovation networks of the NEV industry in China are primarily concentrated in the Beijing-Tianjin-Hebei and Yangtze River Delta regions;the innovation networks in the Pearl River Delta region are significantly weaker.Additionally,regions with poor innovation could achieve more innovation cooperatively.(2)For the network characteristics,the national innovation network presents a“core-edge”structure,and the State Grid is the most important innovation actor of the network.In the Beijing-Tianjin-Hebei region,large state-owned enterprise groups control the network which has a prominent“core-edge”structure,the most active collaborative innovation,and a high degree of network extroversion.Regarding the innovation network in the Yangtze River Delta,the types of actors in the region are diversified,the“core-edge”structure is prominent,the intensity of cooperative innovation is high,and the degree of network extroversion is relatively high.In the Pearl River Delta,private enterprises are the principal actors in the network,the regional network structure is loose,cooperative innovation is limited,and the network is highly extroverted.(3)For regional proximity mechanisms in the Beijing
