【摘要】 “丝绸之路经济带”是联通亚欧非大陆的新型经济一体化大走廊,2015年3月,国家发改委、外交部、商务部联合发布《推动共建丝绸之路经济带和21世纪海上丝绸之路的愿景与行动》,文中指出“丝绸之路经济带”应依托国际大通道,以沿线的中心城市为支撑,以重点经贸产业园区为合作平台,共同打造新的国际经济合作走廊。可以看出,沿线中心城市不仅是各区域的增长极,同时也是“丝绸之路经济带”的支点,如果把“丝绸之路经济带”比作是一个“网络”,那么沿线的中心城市就是网络中的“节点”。以沿线中心城市为节点连接而成的城市网络对于加强区域经济合作、深入推进“丝绸之路经济带”的建设具有重要的意义。基于此,本文从金融服务业企业布局视角构建“丝绸之路经济带”中心城市网络,借助四个指标系统的分析城市网络的结构特征和城市节点的特征。首先,本文整理了国内外关于城市网络和中心城市方面的相关研究理论,为后续中心城市的选取以及模型的构建奠定基础;其次,本文根据官方文件及其他学者的研究文献界定了本文所研究的“丝绸之路经济带”沿线的空间范围,筛选出范围内的中心城市,并结合选定的金融服务业企业的空间布局数据,构建“丝绸之路经济带”中心城市网络模型;再者,通过城市的相对连接率、紧密中心性、城市网络K-核结构和城市网络的基础关联树对构建的中心城市网络进行分析,刻画了城市节点的特征和城市网络的核心结构特征;最终,本文得出以下结论:(1)整个中心城市网络发展较为成熟,中心城市之间联系紧密,通达性较好,核心城市突出,整个网络呈现以伦敦和巴黎为核心的双核心结构,整个城市网络的重心位于北线。(2)分别得出了三条线路的核心城市:北线的核心城市是伦敦和巴黎,同时伦敦和巴黎也是整个城市网络的双核心城市;中线的核心城市是米兰,南线的核心城市是孟买。(3)各线路对“丝绸之路经济带”的支撑强度不同,其中北线金融实力最强,对城市网络起到了最关键的支撑作用;南线也发挥了较强的支撑作用;中线由于发展两极化严重,支撑作用稍弱。(4)我国的9个中心城市均处于主核内,在城市网络中发挥着重要作用,但是相对连接率和紧密中心性都不高,说明金融实力一般,对网络的影响力有限。作为“一带一路”倡议的发起国和推动国,金融实力和影响力亟须提升。更多还原

【Abstract】 "Silk Road Economic Belt"is a new economic integration corridor which provides a connectivity for Asian,European,and African continent.In March 2015,National Development and Reform Commission,Foreign Ministry,and Ministry of Commerce jointly release"the vision and action on promoting the establishment of Silk Road Economic Belt and Maritime Silk Road in the 21th century".The thesis points out that,Silk Road Economic Belt"should rely on the international thoroughfare,regards the key economic and trade industrial region as the cooperative platform,supported by the central cities along the Silk Road,to collectively build a new corridor for International Economic Cooperation.It is observed that central cities along the Silk Road are not only the poles of growth for all regions,but also the fulcrum of"Silk Road Economic Belt".Ift the"Silk Road Economic Belt"is compared to a"network",those central cities along the Silk Road should be the nodes of the network.The urban network,which is connected by the central cities along the Silk Road as the nodes,brings a great significance for the building of deeply advancing the"Silk Road Economic Belt"and enhancing the regional economic cooperationBased on the above content,this paper,from the perspective of financial services in enterprise layout,constructs the network of central cities along the Silk Road,and by means of four indicators systematically analyzes the structural characteristics and the node characteristics of the network in central cities.Firstly,this paper sorts out relative research theories about urban network and central cities at home and abroad,which lays a foundation for the subsequent selection of central cities and the model construction.Secondly,in terms of official documents and other academics’literature review,this paper defines the spatial scope which will be studied along the Silk Road,finds out the central cities within the scope,and through the spatial layout data of the selected financial services,constructs the network model of central cities of "Silk Road Economic Belt".Thirdly,by the virtue of the city’s relative connectivity.,close centrality,the K-core structure and basic association tree of the urban network.The constructed network of the central cities is analyzed and characterized by the urban nodes and the core structure of urban network.Finally,this paper would draw the following conclusions:(1)The network of-central cities is well-developed,and all central cities maintain a close relationship with a great accessibility,especially the core cities;the whole network appears the double-core structure of respectively taking London and Paris as a core,and the heart of the whole urban network lies in the northern line.(2)It can be concluded the core cities of three lines:London and Paris which are the core cities of the northern line and also as the double-core cities of the whole urban network;Milan as the core city of the middle line;Bombay as the core city of the southern line.(3)All lines have different supporting strength,of which the northern line is the best in financial power and plays a significant role in supporting the urban network;the southern line support much of the urban network but less than the northern one;the middle line supports little of the urban network because of serious polarized development.(4)The nine central cities of our country all are in main core,and play a crucial role in the urban network.However,the nine central cities have a not-high relative connective rate and close centrality,which demonstrates their ordinary financial power and restricted impact on the network.As the country in initiating and promoting"the Road and Belt"proposal,it is so urgent to improve its financial power and impact.更多还原
