西部陆海新通道是位于我国西部地区的一条物流运输新通道，对“一带一路” 的发展有着重要的作用，为西部地区的经济发展带来了重大的机遇。物流业是经 济增长的关键因素，其效率的提升对于经济发展至关重要。加之国家政策和现实 问题的双重引导，研究通道内的物流效率成为一项既必要又紧迫的任务。该研究 将有助于挖掘物流效率提升的潜力，提出有效的优化措施，从而推动物流业乃至 整个经济的健康发展。 本文以西部陆海新通道地区内十四个省份为研究对象。第一步，构建科学严 谨的评价指标体系，运用数据包络模型对2012-2021年通道内十四个省份的物流 效率进行静态与动态的分析；第二步，基于修正的引力模型构建了通道物流效率 空间关联网络，然后运用社会网络分析法对其整体结构、个体结构进行分析；第 三步，使用QAP模型对影响物流效率空间关联网络的因素研究，提出可供参考 的对策建议提升通道内的物流效率。主要结论如下： （1）2012-2021 年间西部陆海新通道的物流效率整体是上升的趋势，但部 分省(市)存在投入与产出不匹配的情况，影响了该地区的整体的综合效率；研究 期内西部陆海新通道整体物流TFP大于1为正增长；但分各省市来说，正增长 的省份只有6个，仍具有发展空间。 （2）西部陆海新通道省份节点在空间上呈现不均衡的特征，但随着时间的 变化，区域之间的差异逐渐变小。区域内广东、广西、陕西以及四川在物流网络 结构中占据核心地位，均对周边城市存在一定程度的吸引力，新疆、西藏、宁夏 在物流网络中的地位比较低。 （3）通过影响因素的分析，发现地理空间距离、产业结构、交通发展水平、 对外开放水平、物流信息化水平和物流投资这六个因素对通道物流效率空间关联 网络结构的形成和演化具有推动的作用，最后根据影响因素的分析，提出提高西 部陆海新通道物流效率的对策建议。 

The new western land-sea corridor is a new logistics and transportation channel located in the western region of China, which plays an important role in the development of the "Belt and Road" and brings major opportunities for the economic development of the western region. The logistics industry is a key factor in economic growth, and its efficiency improvement is essential for economic development. Coupled with the dual guidance of national policies and practical problems, it has become a necessary and urgent task to study the logistics efficiency in the channel. The study will help tap the potential of logistics efficiency improvement and propose effective optimization measures to promote the healthy development of the logistics industry and the economy as a whole. In this paper, 14 provinces in the Western New Land-Sea Corridor region are taken as the research objects. The first step is to construct a scientific and rigorous evaluation index system, and use the data envelopment model to analyze the logistics efficiency of 14 provinces in the channel from 2012 to 2021. In the second step, the spatial correlation network of channel logistics efficiency was constructed based on the modified gravity model, and then the overall structure and individual structure of the channel logistics were analyzed by using the social network analysis method. In the third step, the QAP model is used to 兰州财经大学硕士学位论文 西部陆海新通道物流效率空间关联影响因素研究 study the factors affecting the spatial correlation network of logistics efficiency, and put forward countermeasures and suggestions for reference to improve the logistics efficiency in the channel. The main conclusions are as follows: (1) From 2012 to 2021, the logistics efficiency of the new western land-sea corridor was on the rise, but there was a mismatch between input and output in some provinces (cities), which affected the overall comprehensive efficiency of the region. During the study period, the overall logistics TFP of the Western Land-Sea New Corridor was greater than 1, which was a positive growth. However, in terms of provinces and cities, there are only 6 provinces with positive growth, and there is still room for development. (2) The nodes of the provinces of the new western land-sea corridor are spatially uneven, but the differences between regions gradually become smaller with the change of time. Guangdong, Guangxi, Shaanxi and Sichuan occupy the core position in the logistics network structure, all of which have a certain degree of attraction to the surrounding cities, while Xinjiang, Tibet and Ningxia have a relatively low status in the logistics network. (3) Through the analysis of influencing factors, it is found that the six factors of geospatial distance, industrial structure, transportation development level, opening up level, logistics informatization level and investment have a promoting effect on the formation and evolution of the spatial correlation network structure of the corridor logistics efficiency.
