西部陆海新通道是位于中国西部地区腹地一条重要的交通通道，其向北连接 丝绸之路经济带，向南连接 21 世纪海上丝绸之路，同时与长江经济带协同发展， 其物流网络的建设与优化对推动西部陆海新通道建设至关重要。物流枢纽作为物 流体系的核心设施，是现代商贸流通体系的重要承载节点，其建设水平对区域物 流业的集聚能力和服务水平有着重要影响。因此，研究西部陆海新通道中物流枢 纽的发展路径，从复杂网络视角探究其发展的影响因素并明晰其作用机理，有助 于给出物流枢纽建设的合理规划，推动西部物流业的发展。 本文研究内容有三个方面： （1）以西部陆海新通道中涉及的 132 个地级市的物流业为研究对象，研究 了其物流网络的结构特性并遴选了物流枢纽。首先采用熵权法计算各城市的物流 质量，通过辐射模型测度节点之间辐射强度，并利用真实路网数据进行裁剪得到 西部陆海新通道物流网络；其次，采用复杂网络方法对该物流网络各节点城市的 加权度数中心度、接近中心度和中介中心度等个体特征进行了分析；最后，综合 考虑节点城市的物流质量和网络中心性两个因素，遴选出成都、重庆、西安、昆 明等四个物流枢纽。 （2）研究了影响物流枢纽发展的主要因素。对照《西部陆海新通道总体规 划》文件中规划的物流枢纽，发现在复杂网络视角下，部分规划枢纽节点未能充 分发挥枢纽作用，为明晰其原因，论文构建了面板数据回归模型，通过选取适当 的解释变量和被解释变量进行深入研究，发现区域生产总值、物流相关从业人员 数以及货运量等构成影响节点枢纽功能发挥的主要因素，并进一步研究了这些因 素影响物流枢纽发展的作用机理。 （3）研究了物流节点枢纽功能提升的路径。以兰州市为例，分析兰州市发 展现状，找出兰州市与西部陆海新通道物流网络中遴选出的物流枢纽在区域生产 总值、物流人才、货运量等方面存在的差距，并分别从提高物流人才培养质量、 优化产业结构、加大交通基础设施建设力度等方面提出兰州市发挥物流枢纽功能 的对策建议。

transportation corridor located in the hinterland of western China, connecting the Silk Road Economic Belt to the north and the 21st Century Maritime Silk Road to the south, as well as developing in synergy with the Yangtze River Economic Belt. The construction and optimisation of its logistics network is crucial to promoting the construction of the New Western Land and Sea Corridor. As a core facility of the logistics system and an important node of the modern trade circulation system, the construction level of logistics hubs has a significant impact on the agglomeration capacity and service level of the regional logistics industry. Therefore, studying the development path of logistics hubs in the new western land and sea corridor, exploring the influencing factors of their development and clarifying their mechanism of action from the perspective of complex networks, will help to give reasonable planning for the construction of logistics hubs and promote the development of western logistics industry. The research in this paper covers three aspects: (1) The logistics industry of 132 prefecture-level cities involved in the New Western Land and Sea Corridor is studied, and the structural characteristics of their logistics networks and the selection of logistics hubs are investigated. Firstly, the entropy weight method is used to calculate the logistics quality of each city, and the radiation intensity between the nodes is measured by the radiation model, and the real road network data is used to cut to obtain the logistics network of the Western Land and Sea New Corridor; secondly, the individual characteristics of each node city of the logistics network, such as weighted degree centrality, proximity centrality and intermediary centrality, are analysed using the  complex network method; finally, the logistics quality and network centrality of the node cities are considered comprehensively. Finally, four logistics hubs, including Chengdu, Chongqing, Xi'an and Kunming, were selected by taking into account the logistics quality and network centrality of the node cities. (2) The main factors affecting the development of logistics hubs are studied. In order to clarify the reasons for this, the thesis constructs a panel data regression model and conducts an in-depth study by selecting appropriate explanatory and explanatory variables. The main factors influencing the function of nodal hubs are identified, and the mechanism by which these factors influence the development of logistics hubs is further investigated. (3) Study the paths to enhance the functions of logistics hubs. Taking Lanzhou City as an example, the current development situation of Lanzhou City is analysed, and the gaps between Lanzhou City and the selected logistics hubs in the logistics network of the New Western Land and Sea Corridor in terms of regional gross domestic product, number of logistics-related employees and freight volume are identified, and countermeasures and suggestions for Lanzhou City to bring into play the functions of a logistics hub are proposed in terms of increasing infrastructure construction, optimising industrial structure and improving the quality of logistics personnel training.
