基于城市联系强度与城市流的京津冀城市群空间联系研究   总被引:4,自引:0,他引:4  
强化空间联系是破解京津冀城市群发展瓶颈的重要途径.从区域和产业两大维度,采用经济联系强度模型与城市流模型对京津冀城市群进行了实证研究,结果表明:与长三角城市群相比,京津冀城市群之间存在一定程度的空间联系,但较为松散.京津之间经济联系非常紧密,而与其他城市联系均相对松散,说明京津两市的空间集聚效应大于扩散效应;石家庄、唐山与京津空间联系最为紧密,唐山由于产业结构偏重,城市流不如石家庄,两者依然是京津冀城市群次核心城市的主要候选者;其余城市与京津的联系强度及城市流都较小,说明其与京津的落差在进一步加大,这也导致了其承接京津产业转移存在较高难度,京津“孤岛”仍将进一步持续.  相似文献

基于城市经济能级模型对京津冀城市群内各城市进行等级划分,借助引力模型分析城市间经济联系的变化,并利用城市群发展质量评价指标体系和空间自相关分析,对京津冀城市群和群内城市发展质量以及京津冀、长三角、珠三角三大城市群内核心城市发展质量进行评价。结果表明:城市群内一级中心城市北京、天津的辐射影响突出,集聚效应明显,城市间联系的网络化趋势在增强;城市群内各城市发展质量分为发展良好、发展中等、发展一般3个层次,北京和天津的城市发展质量指数高于河北11个城市,北京城市发展质量指数高于三大城市群内其他中心城市;基础设施网络化的发展促使城市群内城市发展质量和城市间联系的紧密程度呈"带状"结构发展。  相似文献

中国城市群多中心网络的拓扑结构   总被引:6,自引:1,他引:5  
在既有理论基础上扩展了城市群多中心网络的度量工具,考察中国12个城市群总部—分支机构的企业关联网络,比较梳理了地级城市空间联系的拓扑结构。实证研究发现:①包括长三角、珠三角和京津冀三大典型城市群在内,中国城市群内部网络系统的拓扑结构依然发育不完善,在联系数据方面均呈现出一定的稀疏矩阵特征,空间组合关系均为树状结构。②总部区位(出度)的层级性差异均高于分支机构区位(入度)的层级性差异,显示出城市群内部空间“流”的不对称性。③针对12个城市群内部网络的拓扑结构聚类分析表明:长三角、珠三角、京津冀、山东半岛、海峡西岸地区的城市群内部网络联系较为紧密,呈现出一定程度的一体化网络特征;其中三大典型城市群存在明显的企业总部集聚核心,其余城市群内部的网络联系松散,跨城企业联系比重较低,在拓扑结构上大多呈现出以省会或副省级城市为指向的向心式联系。  相似文献

京津冀城市群协同发展作为国家战略,如何实现协同创新是城市群协同发展的关键。通过创新系统主体授权专利合作,研究京津冀城市群的创新联系,揭示京津冀城市群创新网络的空间组织和演化特征。结果表明:京津冀城市群创新网络经历了初级发展阶段(2000—2005年)、增强发展阶段(2005—2010年)和扩展与快速发展阶段(2010—2015年)。从空间发展角度来看,北京、天津是京津冀城市群的创新中心,在网络中具有较强的控制力与自主创新能力,京津冀城市群逐步形成"双核+多节点"的创新网络格局。围绕主要城市的创新,京津冀城市群创新网络形成一些小组团创新网络结构。  相似文献

本文分析了2003—2018年中国12个规模较大的城市群的空间体系特征及其变动趋势,并借助城际投资联系数据,分析了各城市群城市网络特征,实证检验了城市网络联系度对城市群空间体系集聚水平的影响。研究发现,2003—2018年城市群空间体系总体呈均衡化发展趋势,且不同城市群城市网络特征差异明显,按发育程度可以分为四种类型:联系紧密-结构均衡-强中心带动型城市网络,联系紧密-弱中心带动-相对开放型城市网络,结构均衡但联系相对较弱型城市网络,以及联系相对较弱且结构极化型城市网络。实证结果证实了城市网络联系的紧密程度和连通度的提高有利于降低城市群空间体系的极化水平,城市网络联系带来的外部性有助于避免城市群空间体系的过度极化及由此带来的集聚负外部性,实现更加均衡的城市群空间结构。但城市网络联系对城市群空间体系均衡化发展的作用依赖于城市网络的结构特征,城市网络结构的极化对城市群空间体系均衡化发展存在抑制作用。  相似文献

黄河流域中上游四大城市群经济联系和网络结构比较分析   总被引:1,自引:0,他引:1  
以黄河流域中上游兰西、宁夏沿黄、呼包鄂榆和关中城市群为研究区域,运用引力模型和社会网络分析等方法,测度各城市群内部经济联系,分析城市群内部城市等级结构,从中心性、网络密度和凝聚子群3个方面对各城市群网络结构进行分析,结果表明:(1)各城市群内城市等级结构不一,兰西、宁夏沿黄和关中均分为3个等级,呼包鄂榆中缺少三级城市;各城市群市(州)之间的经济联系强度与其市(州)等级划分呈现一定协同性。(2)各城市群内经济联系总量及紧密程度不一,兰西、宁夏沿黄、呼包鄂榆内市与市间的经济联系总量最小,但联系最紧密,县与县间联系总量最大,但联系最松散;关中则市与县间联系总量最大且联系最紧密。(3)各城市群的网络结构存在差异,关中对外经济吸引辐射能力、中介能力均最强,宁夏沿黄最弱;网络密度上,呼包鄂榆和关中网络密度较高,兰西和宁夏沿黄较低。(4)对各城市群进行聚类分析,兰西、宁夏沿黄凝聚子群基本依赖行政区划分,呼包鄂榆、关中凝聚子群分割行政区较严重。  相似文献

现有城市网络研究多集中于城市联系及各城市群内部的空间关联,多以企业总分机构关系型数据研究中国城市网络结构,尚较少涉及中国城市群城市网络联系的整体认知。本文基于财富中国500强中的311家金融与专业性服务企业数据,分析中国19个城市群及41个主要城市间城市网络联系,借助企业在属地城市群层面的跨尺度空间表达,依据关系地理将城市群视为互相联系的空间集合,运用网络分析与互锁网络模型相结合的方法,重点分析城市群金融与专业服务业城市网络联系。结论如下:一方面,中国城市群整体形成以京津冀、长三角、珠三角、成渝、山东半岛与长江中游城市群为核心的空间组织体系,并与国家中心城市分布特征一致。关中平原、辽中南、滇中等13个城市群为非核心层级空间组织,是中国城市群空间拓展的重要支撑。另一方面,城市群城市网络联系依赖于金融及专业性服务要素高效优化配置,城市群对外联系范围决定了该城市群对各类服务要素流的控制与配置能力,进而影响其发展地位。其中,京津冀城市群主导商业银行、多元金融投资、保险、会计和律师事务形成的城市网络联系,长三角城市群以绝对优势主导证券企业城市网络联系,长三角、成渝、珠三角城市群共同主导着广告代理、管理咨询企业间的城市网络联系。本文尝试以城市群关系邻近性认知企业行动与城市群间的跨尺度空间联系互馈机理,认为城市群间水平联系对中国城市群城市网络具有重要作用,为国家制定城市群相关政策提供参考。  相似文献

通过引入感应度系数和影响力系数,构建产业联系强度测度模型,探讨了当前长江三角洲与京津冀城市群产业空间联系特征,研究了两大城市群空间经济差异,基于产业空间联系视野对"大都市阴影区"的形成进行了实证研究。研究表明:①城市群内部各城市间产业联系强度越高,城市群整体经济发展水平就越好;②城市群的中心城市与其他各城市产业联系强度越高,城市群整体经济发展水平就越好、越趋于均衡;③从产业空间联系来看,中心城市与其邻近的外围地区的产业联系强度弱化是造成"大都市阴影区"形成的关键因素。  相似文献

区域协同发展的过程,本质是经济领域相互作用,城市群经济联系不断增强的过程。从经济联系的视角通过对京津冀城市群与长三角地区沪苏浙城市群的对比分析发现,无论是从经济发展的梯次结构还是与中心城市的经济联系,沪苏浙地区都优越于京津冀。立足现实,深化对这一问题的思考,借助雄安新区的规划与建设,就改变京津冀城市群中北京“一城独大”式的发展模式以及带来的一系列负效应,构筑梯次良好、经济互通密切的城市空间布局提出对策建议。  相似文献

"十五"时期环渤海城市群经济联系分析   总被引:8,自引:1,他引:7  
环渤海城市群是中国北方重要的经济增长区域,未来发展前景十分广阔,分析"十五"时期环渤海城市群经济联系的动态变化规律必将为"十一五"乃至更长一段时期环渤海城市群空间经济联系产生"抛砖引玉"的功效。选取"十五"时期环渤海地区京津冀、辽中南、山东半岛共28座城市的市区从业人员、GDP、人均GDP等指标,利用城市流强度等模型测度了三大城市群内部经济联系强度,并与长三角、珠三角共25座城市相比较。结果表明:京津冀城市群经济联系强度居环渤海地区首位,辽中南次之,山东半岛位居最后;"十五"期末与期初相比,京津冀、辽中南的经济联系强度均呈上升态势,其中,尤以京津冀上升幅度最大,而山东半岛则出现了明显的下降;与长三角、珠三角相比,京津冀经济联系强度虽弱于长三角,但略强于珠三角,而辽中南、山东半岛与长三角、珠三角的差距则更为显著。  相似文献
