摘　　要：提升产业链供应链韧性和安全水平是我国实现高质量发展的核心抓手,而供应链的网络位置直接影响了供应链韧性和安全状况,因此,研究供应链网络位置特征及其微观经济效应具有重要价值。从理论上探讨供应链网络位置对企业生产效率的影响,并依据企业主要供应商与客户信息构建时间维度上的供应链网络,使用社会网络分析方法计算点度中心度与中介中心度作为企业供应链网络位置的特征指标,实证检验供应链网络中心性对企业全要素生产率的影响。结果表明:供应链网络中心位置优势能够显著促进企业生产效率的提升,具体以促进企业协同创新、优化资源配置及降低经营成本为渠道机制。此外,企业的协同动机、战略距离、供应链距离、信息效率、合作倾向及管理者战略眼光等特征会带来差异化的影响。厘清供应链网络对微观企业发展的影响机制,能为维护我国产业链供应链安全稳定以及依托现代化供应链驱动企业高质量发展提供重要参考。Improving the resilience and security level of the industrial supply chain is crucial for China to achieve high-quality development,and the network location of the supply chain directly determines the resilience and security status of the supply chain,thus having important practical significance.The existing literature mostly takes supplier concentration or customer concentration as the main measurement index of supply chain relationship,while the empirical research on supply chain network and its micro-economic effects are still rare.In view of it,this paper analyzes the internal mechanism that the location of supply chain network affects the production efficiency of enterprises,and constructs the supply chain network in the time dimension based on the information of the main suppliers and customers of listed companies,and uses the social network analysis method to calculate the point centrality and intermediary centrality as the characteristic indicators of enterprise network location.From the perspective of supply chain network,this paper empirically examines the impact of network centrality on enterprise total factor productivity.The results show that the advantage of supply chain network center location can significantly promote the improvement of enterprise production efficiency.Specifically,the key channel mechanism is to promote collaborative innovation,optimize resource allocation and reduce operating costs.In addition,the differences in enterprises'collaborative motivation,strategic distance,supply chain distance,cooperation tendency,information efficiency and managers'strategic insight will bring about differentiated impacts.In general,this paper clarifies the theoretical mechanism of supply chain network for the development of enterprises,and provides a reference for further maintaining the resilience,security and stability of China's industrial supply chain and driving the high-quality development of enterprises.
