摘　　要：多层城市网络联系的交叉汇聚形成了更加开放的创业生态系统边界,城市创业活力愈发受到网络外部性的影响。在构建交通流、资金流和知识流交织汇聚的多层城市网络的基础上,实证检验城市多层网络中心性对创业活力的影响。研究发现:多层城市网络中心性对创业活力的提升具有显著的促进作用,且受网络连接协调组织成本的影响,可能已处于边际收益递减阶段。进一步研究发现,多层城市网络中心性对创业活力的影响存在行业异质性,如以解析型知识为基础的生物医药行业对网络资源的依赖性明显高于以合成型知识为基础的节能环保行业等。在此基础上提出相应的政策建议,以期有助于深化对城市创业生态系统发育规律的认识,更好把握多层城市网络体系和创业生态系统的互动发展。The intersection and convergence of multi-dimensional urban network connections form a more open entrepreneurial ecosystem boundary,and urban entrepreneurial vitality is increasingly affected by network externalities.This paper constructs a multilayer city network with interwoven traffic flow,capital flow and knowledge flow,characterizes the entrepreneurial vitality of the city by the number of new enterprises,and empirically tests the impact of the network centrality in the multilayer network on the entrepreneurial vitality of the city.Two conclusions are drawn:Multilayer city network embeddedness has a positive impact on the promotion of urban entrepreneurial vitality,and this positive impact may have been in the declining stage of marginal reveneue due to the weakening of the cost of network connection coordination organization.Furthermore,The impact of urban multilayer network centrality on entrepreneurial vitality has industry heterogeneity heterogeneity.The biomedicine industry based on analytic knowledge is significantly more dependent on network resources than the energy conservation and environmental protection industry based on synthetic knowledge.These findings provide reference for deepening the understanding of the development laws of urban entrepreneurial ecosystems and understanding the interactive development of urban multiple network systems and entrepreneurial ecosystems.
