摘　　要：基于金融科技企业投资数据构建区域间的金融科技空间联系网络,运用趋势面分析、模体分析方法、网络中心度以及网络社团发现算法分析网络的全局特征与结构特征,并运用指数随机图模型(ERGM)探究金融科技网络的影响因素。结果表明:(1)中国金融科技本地关联空间分异特征较为显著,表现出明显的空间不平衡性,外部关联网络演变逐渐复杂,呈现出由区域中心型网络逐渐向均衡型的复杂网络结构过渡,覆盖广度也明显提升。(2)省级网络与市级网络具有一定结构异质性,拥有关联趋向性的模体是金融科技空间联系网络的重要组成结构。网络社团发现有金融科技企业投向超越地理约束的投资模式转变。(3)网络自组织效应、节点属性效应、多维邻近效应均是影响金融科技网络形成的重要因素。Based on the investment data of financial technology enterprises,this article constructs the spatial connection network of regional financial technology,and analyzes its global and structural characteristics by the methods of trend surface analysis,model analysis,network centrality and network community discovery algorithm.It uses the exponential random graph model(ERGM)to explore the influencing factors of the financial technology network.The results show that:1)China’s financial technology local linkages are characterized by significant spatial differentiation,showing obvious spatial imbalance.The evolution of the external linkages network is gradually complex,showing a gradual transition from a region-centered network to a balanced complex network structure,and the coverage is also significantly improved.2)The provincial-level network and the municipal-level network have certain structural heterogeneity,and the model with correlation tendency is an important component of the spatial connection network of financial technology.It’s found that there is a shift in the investment model of financial technology enterprises beyond geographical constraints.3)Network self-organization effect,node attribute effect and multi-dimensional proximity effect are all important factors that affect the formation of financial technology network.
