摘　　要：以城市群、都市圈为主的城市区域已经成为代表我国参与全球竞争及合作的主要载体,并且其内部的产业链功能组织状况对城市区域的一体化水平起到至关重要的影响,而长三角作为全国对外开放程度最高、经济发展最具活力的城市区域之一,对其汽车制造产业链投资网络开展研究可以为其他城市群提供一定的参考及示范作用。本文基于长三角的工商企业注册数据库,借助社会网络分析、社区发现等方法,从汽车制造产业链整体、上游和中游环节入手来分析其投资网络的多尺度空间特征,并运用地理探测器来探析各环节投资网络的影响因素。结果显示:(1)长三角汽车制造产业链整体、上游、中游投资网络分别呈“双强核多中心辐射状”“单强核多中心放射状”“单弱核多中心辐射状”的空间结构。(2)长三角汽车制造产业链整体、上游、中游投资网络可分别划分为4、4、6个社区,并且中游的模块化水平较好。(3)整体和上游投资网络的城市节点中心度高值区主要沿沪宁合杭甬发展带、南部沿海发展带分布。(4)政策支持水平、经济产业水平、对外经济水平、人力资源水平是影响汽车制造产业链各环节投资网络空间格局的主要因素,但同一因子对不同环节的影响强度有所差异。(5)交互探测结果显示,各环节投资网络的不同影响因子交互后表现为双因子增强和非线性增强2种,其中双因子增强效应占主导。相关研究结果对于提升长三角内部的城市间产业分工协作,促进区域一体化发展具有重要意义。The urban area dominated by urban agglomerations and metropolitan areas has become the core carrier representing China's participation in global competition and cooperation,and its internal industrial chain function organization status has a crucial impact on the integration level of urban areas.The Yangtze River Delta is one of the most open and dynamic urban areas in China,and the research on the investment network of its automobile manufacturing industry chain can provide some reference and demonstration for other urban agglomerations.The paper is based on the registration database of industrial and commercial enterprises in the Yangtze River Delta.Using methods such as social network analysis and community discovery,it analyzes the multi-scale spatial characteristics of the investment network of the automobile manufacturing industry chain as overall,upstream,and midstream links,and uses geodetectors to explore the influencing factors of each link's investment network.The results show that:(1)The overall,upstream,and midstream investment networks of the automobile manufacturing industry chain in the study area exhibit spatial structures of"dual strong core multi-center radiation","single strong core multi-center radiation",and"single weak core multi-center radiation",respectively.(2)The overall,upstream,and midstream investment networks of the automobile manufacturing industry chain in the delta can be divided into 4,4,and 6 communities,respectively,and the modularity level of the midstream is good.(3)The urban node centrality high-value areas of the overall and upstream investment network are mainly distributed along the"Shanghai-Nanjing-Hefei-Hangzhou-Ningbo"development belt and the southern coastal development belt.(4)The level of policy support,economic industry level,external economic level,and human resource level are the main factors that affect the spatial pattern of investment networks in various links of the automotive manufacturing industry chain,but the impact intensity of the same factor on differ
