摘　　要：基于长三角地区金融企业总部分支机构数据构建金融网络,以中心度指标刻画城市的金融网络嵌入特征,以专利申请数量衡量城市创城水平,探讨金融网络嵌入与城市创新水平两者之间的关系。研究发现:金融网络的知识管道效应已成为影响城市创新水平的重要因素;得益于长三角地区交通基础设施的完善以及信息搜寻成本的降低,地理距离对知识溢出和转移的约束作用正在减弱,知识溢出效应更加依赖于网络邻近性而非场所空间中的区位优势;金融网络嵌入的知识溢出效应呈现出空间异质性特征,扮演“知识守门人”角色处于核心地位的城市能够从网络链接中获得更大的收益。未来,应进一步加大超越长三角区域的金融网络建设,并实施差异化的创新发展政策,充分发挥高创新水平城市的辐射带动能力,低创新水平城市则应借助网络外部性提升自身创新水平。Based on the branch data of the headquarters of financial enterprises in the Yangtze River Delta region,the financial network is constructed,the centrality index is used to depict the financial network embeddedness of cities,the number of patent applications is used to represent the innovation level of cities,and the influence of financial network embeddedness on the innovation level of cities and its heterogeneity characteristics are empirically tested.The results show that:the knowledge pipeline effect of financial network has become an important factor affecting the level of urban innovation.Thanks to the improvement of transportation infrastructure in the Yangtze River Delta and the reduction of information search cost,the constraint effect of geographical distance on knowledge spillover and transfer is weakening,and knowledge spillover effect is more dependent on network proximity rather than location advantage in place space.The knowledge spillover effect embedded in financial network presents spatial heterogeneity,and the core city playing the role of“knowledge gatekeeper”can gain more benefits from network links.he construction of financial networks beyond the Yangtze River Delta region should be further increased in the future,and differentiated innovation development policies should be implemented to give full play to the radiation-driven capability of cities with high innovation levels,while cities with low innovation levels should leverage on network externalities to enhance their own innovation capabilities.
