多维邻近视角下长江经济带区域金融空间联系特征及其影响机制

研究运用引力模型、网络分析、聚类分析、空间自相关分析和经济重心模型等方法剖析了长江经济带区域金融空间联系网络特征以及联系总量格局,并在多维邻近视角下采用空间杜宾模型探究了区域金融能力与金融网络规模的影响机制,研究发现:①"多核心"的金融空间联系网络格局较为稳定,网络复杂度持续升级,呈现"东密西疏"的空间分布特征,且在空间上形成三大层级性明显的金融辐射圈;②金融空间联系格局展现出"核心-边缘"的发展形态,空间集聚特征明显,发展重心在演进过程中呈现反"Z"形变化特征;③金融空间联系能通过信息技术发展打破传统地理空间距离壁垒,具有明显的多维邻近效应,其中城市经济规模、工业基础能力、产业升级导向和城市创新能力是区域金融能力与金融网络格局形成的主要影响因素,而政府供给导向因素具有较强的空间溢出效应,区域间的政府竞合行为有利于金融要素的流转与联系。

The Characteristics of Regional Financial Spatial Linkages and Influencing Mechanism in Multi-Dimensional Proximity in the Yangtze River Economic Belt

This paper analyzes the financial spatial connection characteristics of the Yangtze River Economic Belt by using gravity model,network analysis,cluster analysis,spatial autocorrelation analysis and economic barycenter model,and explores the influencing factors.The results show that the"multi-core"financial spatial linkages network pattern is relatively stable,and the network complexity continues to escalate,forming three major levels of financial radiation circles in space.Besides,The financial spatial connection pattern shows the development pattern of"core-edge",the spatial agglomeration features are obvious,and the development center of gravity exhibits anti-"Z"-shaped variation characteristics in the evolution process.In addition,it has obvious multi-dimensional proximity effects,which the urban economy scale,industrial basic capacity,industrial upgrading orientation,and urban innovation capability are the main influencing factors in the formation of financial spatial linkage spatial pattern,while government supply orientation factors have strong spatial spillover effects,and inter-regional government competition behavior is conducive to the transfer of financial factors.
