The large urban agglomerations are the main form of spatial organization of urbanization, and they have become the powerful engine of national economic development. Since reform and opening-up, China has re-integrated into the world economic system, and both industrialization and urbanization have accelerated the enlargement of scale of large urban agglomerations and upgraded their function level. This paper firstly defines the concept of Chinese metropolitan areas based on the data attained from the fifth national census, and distinguishes the three types of Chinese metropolitan areas. In 2000, China had a total of 117 metropolitan areas, of which twenty-six areas had a population of 2 million or more. Then, the paper defines the concept of large urban agglomerations in China, and summarizes the basic features of 13 large urban agglomerations. This paper uses the metropolitan area as the basic unit to define the concept of large urban agglomerations in China, then analyzes their spatial distribution and roles in regional development. And the author thinks that Chinese large urban agglomerations play important roles as the centre of gravity of the national economy and the growth engines in regional development.

流空间是认识城市网络结构和演化的重要手段。近年来大数据的快速发展为流空间研究提供了新的机遇和挑战。论文系统综述了基于大数据的流空间研究进展。首先,论文梳理了基于大数据流空间研究的背景和历史,然后总结了基于大数据的流空间研究的主题、数据类型、方法和主要发现,最后展望了未来的研究挑战。2011年以后,基于大数据的流空间研究呈指数增长趋势,中英文论文年均发表量从2010年的11篇增长到2018年的106篇。大数据主要从提供新的数据源、激发新的分析方法和提供新的研究视角三方面推进了流空间研究。常用于流空间研究的大数据主要包括手机信令数据、社交媒体签到数据、公共交通刷卡数据和出租车轨迹数据,它们比传统统计数据更能直接提供人流、物流和信息流的时空动态信息。研究方法也从传统的基于距离的重力模型发展为网络分析方法。未来在交叉学科研究、大数据和传统数据的耦合、大数据与深度学习和云计算等新方法的结合方面仍需进一步探索,从理论、数据和方法上全面深化流空间研究。

The studies on the space of flow play an important role in understanding the structure and change of urban networks. The rapid development of big data provides new opportunities and challenges for the studies on the space of flow in recent years. This article systematically reviewed the research progress on the space of flow based on big data. First, we retrospect the background and history of the studies on the space of flow, then summarized the themes, the types of big data, the methods used for the studies and the major findings, as well as discussed the research challenges. We found an exponential growth of studies on the space of flow using big data after 2011. The annual number of published papers increased from 11 to 106 during 2011-2018. Big data deepen the research on the space of flow by providing new data sources, inspiring new analytical methods, and new research perspectives. Four types of big data—mobile phone, social media, smart card, and taxi trajectory data are commonly used in the studies on the space of flow, which can provide information on spatiotemporal flows (such as population flow, material flow, and information flow) directly. Research methods have also evolved from distance-based gravity models to network analysis. In the future, the research on the space of flow using big data can be further improved by validating the effectiveness and representativeness of the big data, the integration of big data and traditional data, and the information mining from big data using new methods such as deep learning and cloud computing.

城市网络是近年来城市与区域研究的一个新方向.基于2003-2013年间8个横截面的中国铁路客运班列数据,采用加权度中心性和社区结构模型,探讨高速铁路建设对城市等级和集聚性空间格局及演化的影响.研究表明:① 基于铁路客运组织的城市等级结构呈现出位序--规模分布的特征和集聚性,且三大地带和各社区内城市也呈现出明显的位序--规模分布,随着高速铁路网络的扩展,加权度中心性的集聚性更明显,并逐步呈现出较为明显的层级结构和社区结构.② 城市等级结构呈现出明显的东中西地带性,廊道效应和经济,人口的耦合性,即基于铁路客运班列的城市等级结构与基于属性数据(人口/GDP)的结果表现出较大的相似性,但也存在一定的差异.城市社区结构与中国高速铁路网络,城市群的空间分布格局基本一致.随着高速铁路的建设,东中西三大地带间城市等级的差异呈扩大态势,但各社区间城市等级的差异呈缩小态势,部分社区核心城市已形成.

The evolution of inter-city network influenced by globalization and information technology has become a hot topic in city and urban research. This study tries to explore the evolution of nodal hierarchy and communities in inter-city network based on passenger train network during the rapid development period of High-speed Railway (HSR) in China since 2003. Results indicate that: (1) the evolved HSR network in China enlarged the disparities of weighted degree centrality between regions, but decreased the disparities of that between communities, and led to an increasing concentrated city hierarchy with fewer cities having high centrality value, and a growing similarity between the city hierarchies measured by the passenger train network and by city attributes (such as population and GDP); (2) the city hierarchy measured by passenger train network followed a rank-size distribution in the national and regional levels, as well as in some communities. (3) Spatially, cities with higher hierarchy in passenger train network and larger improvement in weighted centrality indicator were mostly located in the eastern region or the areas with the distance to the nearest HSR stations below 50 km, developed economy and high population density; the cities in 2013 could be divided into 14 communities, including the communities with cities mainly located along Beijing-Shanghai, Beijing-Wuhan and Wuhan-Chengdu, Wuhan-Guangzhou, Beijing-Jiujiang, Hangzhou-Xiamen, Lanzhou-Urumqi trunk rail lines, and located in Northeast China, Shanxi Province, Inner Mongolia. (4) The evolution of communities was mostly influenced by the natural environment and administrative areas, especially by the development of HSR network.

随着经济全球化和区域一体化的快速发展,城市间的交流日益密切,要素的流动性和互赖性促进了城市网络的形成,并成为一种新的区域组织模式和空间结构。本文基于2018年腾讯人口迁徙数据,构建了372×372关系数据矩阵,并从不同交通方式出发,系统刻画了中国城市网络格局。研究表明：① 网络关联度高的城市主要集中在胡焕庸线以东区域,尤其是长三角、珠三角、京津冀、成渝等城市群地区的聚集程度最高,成为中国城市网络格局的主控力量;而西北半壁的城市处于被支配地位。② 依据迁徙量,将中国城市网络划分为国家级、大区级、区域级、地方级和基座级网络。城市网络结构随交通方式而变化,当网络等级下移时,节点城市趋于增多,网络密度加大,但网络范围趋于缩小,网络等级与迁徙路径存在着密切的关联性,国家级网络与空运相关,区域级网络与铁路运输相呼应,地方级网络与汽车运输相关。③ 不同运输方式的经济时空距离决定了网络结构,是引致网络随路径不同而产生分异的基本因素。

With the rapid development of economic globalization and regional integration, the connection between cities is increasingly close. The mobility and interdependence of elements have promoted the formation of city network and become a new regional organization model and spatial structure. Based on Tencent's migration data, this paper constructs a 372×372 relational data matrix, and systematically depicts the city network pattern in China from different modes of transportation. The results show that cities with high network correlation degree are mainly concentrated in the area east of the Hu Huanyong Line, especially in the Yangtze River Delta, Pearl River Delta, Beijing-Tianjin-Hebei region, Chengdu-Chongqing region and other urban agglomeration areas, which have the highest concentration and become the main control power of China's city network pattern; and the cities in the northwest half are at a disadvantage status. According to the amount of migration, the Chinese city network is divided into national, large regional, regional, local and pedestal networks. The city network structure changes with the mode of transportation. When the network level moves down, the number of node cities tends to increase and the network density increases, but the network range tends to shrink. There is a close correlation between the network level and the migration path. National-level network related to air transportation, regional network related to railway transportation, and local network are relevant to automobile transportation. The economic space-time distance of different transportation modes determines the network structure, which is the basic factor that causes the network to differentiate with different paths.

中国的区域治理模式长期以来呈现出阶段性演化的特征。特别是近些年,传统省-市分层设权的权力组织关系被动态的、反复连续性的博弈所取代。本研究借助政治经济学与人文地理学关于“国家空间再中心化”及组织社会学者的“行政发包制”理论,立足区域基础设施项目,即“珠三角城际铁路网”展开实证,系统分析其规划、建设及运营过程。并聚焦其中的事权与财权动态演变过程,解析省政府的角色定位和省市关系的演变等两大关键问题,揭示中国城市区域治理重构的内在逻辑。研究发现：一方面,省政府的角色定位由“分包商”和“协调者”逐渐转变为协调与发展并重的新角色定位;同时,省市关系由结构化的“行政发包”转化为多轮协商的动态博弈连续体。

Regional governance in China has shown the periodic feature, notably under the city regionalism in recent years. Examining the formation of regional governance in China is conducive to probing the China’s city-regionalization as well as the features of institutional architecture oriented integrated development. The dynamic and continuing game process in terms of power configuration has replaced the traditional multi-level governmental system. Based upon a case study of Pearl River Delta intercity railway, this article examines the dynamic evolution of power and financial right relation in the planning, construction, and operation process systemically. The Pearl River Delta intercity railway is a large-scale infrastructure project in which multiple governments are fully involved and actively sought for their interests. Thereby, the primary objective of this article is to explore the dynamics of regional governance restructuring in China through interrogating the role of provincial government and the evolution of provincial-local relation. There are two important findings reported by this article. First, the role of provincial government has been transformed from subcontractor and coordinator to “subcontractor plus contractor” and “coordinator plus developer”. This indicates that the provincial government has operated towards both gatekeeper and competitor. The financial authority is essential to determining this role transformation. Second, the structural administrative subcontract of provincial-local relation has transformed to serval opposed and cooperation waves of continuum. This continuum has been driven by different types of interests and the provincial-local relation constitutes to the stability and structural coherence of regional governance in China. This finding rectifies existing understanding around the regional governance mechanism, that is top-down and bottom-up mechanisms. As such, the regional governance has generally manifested as the hybrid model in which different governmental agencies co-shaped. The changing regional governance in the Pearl River Delta intercity railway also implies that the regional governance is sensitive to the concrete socioeconomic environment and varied case by case. In this vein, we contribute to the understanding of recentralization of state space as well as the restructuring of provincial-local relation beyond administrative subcontractor. It concludes that China’s city-regionalization is orchestrated by different levels of government and the actual effect and modality of regional governance are determined by inter-scalar politics oriented economic growth.

从流动空间角度出发,建立基于关系测度的空间耦合模型,采用复杂网络分析方法和灰色关联分析方法深入探讨区域信息空间和人口空间的耦合格局。研究发现信息空间和人口空间的耦合网络呈现“核心-边缘”模式,北京、上海、广东、天津、新疆和甘肃等耦合核心省市在整个省市内占据主导地位,是其他省市耦合发展所依附的核心。全国省市信息空间和人口空间耦合分布的总体布局呈现“川”型特征,分为高耦合协调型、中耦合磨合型以及低耦合发展型。信息空间和人口空间的耦合主要分为高耦合协调型、中耦合磨合型以及低耦合发展型3种,其中空间的高耦合程度一方面响应了国家加快推进互联互通建设的发展战略,另一方面也是京津冀一体化以及建设丝绸之路经济带的必然结果。

In the context of informatization, the information system and the population system interact with each other, and the information elements and the demographic factors affect the regional development more and more deeply. Therefor the study on the coupling of information space and population space could provide the government departments with scientific decision for regional development layout. From the perspective of the flow space, a spatial coupling model based on relations measurement is established in this paper. What’s more, complex network analysis and gray correlation analysis are used to discuss the characteristics of the coupling and coupling pattern. The results show that the coupling network of the population space and information space presents "core - periphery" model. As central provinces, Beijing, Shanghai, Guangdong, Tianjin, Xinjiang and Gansu provinces dominate in all provinces, which are attached cores of the other provinces. On the one hand, a coupling degree responses to the national strategy of interoperability, on the other hand it is the inevitable result of the integration of Beijing, Tianjin, and construction of the Silk Road economic belt. All the provinces are divided high coupling coordination group, running coupling group and low coupling development group.

以制造业集聚指数作为测度指标,利用空间面板数据模型检验了地方化、城市化以及全球化要素对制造业整体集聚水平的具体影响。研究发现：① 长三角区域制造业高度集中在苏南?上海?杭（杭州）绍（绍兴）甬（宁波）组成的区域且地位稳固,同时苏北和浙西南地区的制造业虽然比例较低,但是总体地位有所提升。② 地方化要素中的职工工资和开发区变量对县域制造业集聚具有显著的正向作用,土地价格则呈现出显著的负向影响,市场规模和交通的作用不稳定。城市化要素中的城市规模、城镇化率、外来迁入人口以及城市制造业结构多样化均表现出显著的正向促进作用,表明了长三角区域城市化的推进促进了制造业集聚水平的提升。全球化表现出不同的作用方向,其中FDI对制造业集聚指数的影响显著为负,出口变量表现出显著的正向作用。

This article proposes a theoretical framework composed of the effects of localization, urbanization and globalization to explain the evolution of regional manufacturing agglomeration in the Yangtze River Delta region. Further, based on the micro firm-level data from industrial enterprise database in China, using regional manufacturing agglomeration index as a measure index, this paper first described the spatial characters of manufacturing at the county level in the Yangtze River Delta region from 2000 to 2013, and then using the panel data model to measure the effects of localization, urbanization and globalization on manufacturing industry agglomeration. The results are as follows. Firstly, the manufacturing industry is highly concentrated at the region of South Jiangsu, Shanghai and Hangzhou-Shaoxing-Ningbo and changes little over time, and the manufacturing industry status in the north of Jiangsu and south west of Zhejiang has been improved. Secondly, the variables of wage and industrial development zones have a significant positive effect on the manufacturing agglomeration, while the variable of land price has a significant negative effect, and the effect of market and transportation are inconclusive. The urbanization factors, such as city size, urbanization rate, migration and urban manufacturing diversification, all show significant positive promoting effects, indicating that the urbanization will promote the level of manufacturing agglomeration in the Yangtze River Delta region. Globalization shows different directions, which FDI has a significant negative impact on the manufacturing agglomeration, and the variable of foreign capital is also negative, indicating that foreign investment is not conducive to the improvement of the manufacturing agglomeration level. Exports show a positive effect, but it is inconclusive.

以长三角“无障碍旅游圈”的实践为例,通过对地方政府合作过程的梳理,运用博弈分析方法剖析了各城市政府之间共享合作的动力机制及策略选择。结果表明：区域一体化进程中合作达成需要尊重市场意愿,增强政府及公众层面的区域认同,通过不同地方政府间的多重博弈达到成本共担利益共享的“纳什均衡”。这一结论既能丰富地方政府合作研究的案例样本,总结长三角地区的成功经验,也可以为粤港澳大湾区建设过程中的地方政府合作提供参考和启示。

珠三角作为中国东南沿海的巨型城市区域,旨在构建跨越经济社会系统的多元协同的综合一体化地区。本文以深汕特别合作区与穗莞深城际铁路两个区域合作项目为例,借鉴“新国家空间”理论,基于区域治理所面临的经济发展困境与行政治理困境,分析区域治理过程中的权力上移和下移,即省市关系调整的弹性应对策略。研究发现：区域产业合作项目中,为克服城市间合作的制度化不足的行政治理困境,省政府进行了包括资源注入、事权下放、去管制和扩大地方自主权的区域治理权力的尺度下移;区域基础设施项目中,为了解决省政府财权不足的行政治理困境,省政府进行了水平权力重组以构建综合博弈体、强制性地方事权上收和以收权导向的行政奖励的区域治理权力的尺度上移。由此,本文认为珠三角区域治理并非单向、机械的尺度建构过程,而是区域项目建设导向下,以修复行政治理困境为目标,灵活多向的尺度重配过程。

The Pearl River Delta (PRD) is the global city-region in China’s southeast coastal areas and aims to create a comprehensive cross-border region across divergent institutional systems. The city-region in China has been long deemed as the engine of the regional growth in the past four decades. This article draws upon the theory of “new state space” to investigate the two regional projects in PRD, that is Shenzhen-Shanwei Special Cooperation Zone and Sui-Guan-Shen (Guangzhou-Dongguan-Shenzhen) intercity railway projects. By examining the theory of “new state space” from the lens of rescaling, we build up a conceptual framework capable to understand the rescaling of city-regional governance in post-reformed China. Based upon crises of capital accumulation and administrative governance, this article is committed to tracking the upscaling and downscaling of powers in regional governance and the overall rescaling processes of relations between provincial and local governments. In general, this article develops a China-contextualized conceptual framework and two empirical cases to problematize the rescaling of regional governance, both of which are central to shed lights on the rationale of China’s political economy. Three major findings are reported as follows. First, in the industrial collaboration project, in order to overcome the crises of weak institutional framework for intercity cooperation, provincial government is devoted to injecting resources, devolving administrative powers, deregulation, and empowering great autonomies to localities. These actions constitute to the downscaling of regional governance. Second, in the large-scale infrastructure project, in order to overcome the lack of the financial authority, provincial government is committed to building strong bargainer through horizontal power reconfiguration, recentralizing the developmental power from localities compulsorily, and delivering actual incentives for power recentralization. These actions constitute to the upscaling of regional governance. Third, considering the above-mentioned findings, this article argues that rescaling of regional governance in PRD is a flexible and polydirectional rescaling process, which is differentiated by concrete regional projects, rather than a unidirectional and mechanical rescaling process as suggested by conventional literature.

在新时期新背景下,实现粤港澳区域联动发展具有紧迫性、必要性和重大现实意义。本文认为研究粤港澳区域联动发展需要以区域一体化理论体系、“全球—地方”尺度理论、区域空间相互作用理论体系为主要的理论基础。其关键科学问题是研究“一国两制”下粤港澳尺度的区域联动理论,探索粤港澳区域联动的机制、关键因素、模式与路径;提出了粤港澳区域联动发展关注的4个重点议题：①粤港澳区域一体化/协同理论的研究与探索;②粤港澳地位与作用研究;③粤港澳联动的多尺度、多主体影响机制与模式研究;④粤港澳联动发展的实施路径研究。

Given the modern background of economic globalization, regional economic integration, new global economic development trends caused by modern technological reforms, the Belt and Road initiative, and the Guangdong-Hong Kong-Macao Greater Bay Area development strategy, there is a growing sense of urgency, necessity, and practical significance in achieving the joint development of the Guangdong-Hong Kong-Macao region. This requires an in-depth understanding and accurate grasp of the key scientific issues and important topics related to this task. This article argues that research related to the joint development of the Guangdong-Hong Kong-Macau region must be based on a regionally unified theoretical framework, "global-local" scale theory, and regional spatial interaction theory as its theoretical basis. In this regard, key scientific issues include the study of the theory of regional linkages of scale in Guangdong, Hong Kong, and Macau under the "One Country, Two Systems" framework, and the exploration of mechanisms, factors, models, and pathways governing linkages in the Guangdong-Hong Kong-Macau region. In so doing, this article proposes four important topics that can be considered with regard to the joint development of the Guangdong-Hong Kong-Macau region: (1) Research and exploration of unification/coordination theory in the Guangdong-Hong Kong-Macau region under the "One Country, Two Systems" framework; (2) Research related to the location and role of the Guangdong-Hong Kong-Macau region; (3) Research related to the multi-scale and multi-agent impact mechanisms and models for the linkages between Guangdong, Hong Kong, and Macau; (4) Research related to implementation pathways for the unified development of Guangdong, Hong Kong, and Macau.

粤港澳大湾区是在“一带一路”倡议下,由珠三角经济圈的强化合作而产生的新地理概念。作为新兴的全球化港湾,粤港澳大湾区如何突破新自由主义框架理论,探索出符合社会主义市场经济体制的发展路径,是当前决策者和规划者需要思考的重要问题。本文简要梳理了现有的城市群、区域增长极理论,新经济地理集群理论,全球产业链网络理论并结合大湾区现状优势,对湾区发展战略定位与发展路径进行探究,认为可通过粤港澳三方通力合作,创造一个内生型的经济与产业本土增长模式为主要方向。具体表现为：首先,要以先进制造业为立足点、实现自我创新的产业升级,形成完善的制造业产业链,并成为全球生产网络的重要节点与区域性枢纽;其次,大湾区还应利用自身的科研与教育、金融与创新资源优势,推进“一国两制三关税区”、尤其是与香港在大湾区建设中的全方位参与联动,完善产权制度,加强合规和规则经济的市场经济体系建设,将大湾区打造为中国的科创中心及全球性金融中心。

The Guangdong-Hong Kong-Macao Greater Bay Area is a new geographical concept arising from the enhanced cooperation of the Pearl River Delta Economic Zone under China's Belt and Road Initiative. As a new global bay area, how to make a theoretical breakthrough in neoliberalism framework and explore the development pathway in line with the socialist market economic system is an important issue that policymakers and planners need to think about. Based on a systematic review of the existing theories in urban agglomeration, regional growth pole theory, the cluster theory in new economic geography, and the global production network theory, this article seeks for a theoretical framework and grounding for understanding the development issues in the Greater Bay Area. In line with the existing advantages of the Greater Bay Area, this article identifies the strategic positioning and development pathway for the area, and argues that creating a new development model of endogenous growth with indigenous innovation is the first development priority for the Greater Bay Area. That is, through deepening the cooperation between Guangdong, Hong Kong, and Macau under "one country, two systems, three tariff zone," the Greater Bay Area could first achieve the transformation and upgrading in advanced manufacturing industry and secure a strategic position as an important regional hub in the global production network. Second, the Greater Bay Area should also use its own strengths in education, scientific research, and international financial services to develop China's innovation hub and global financial center with strong property rights, compliance, and rule-based economic system.

构建中国180×180的O-D城市日高铁流量矩阵,基于社会网络分析研究其高铁网络结构特征,结果表明：① 中国高铁网络松散,东、中部网络密度大于东北与西部,以长三角为核心的东南与其他区域不均衡特征凸显,东、中、西、东北包含不同的高铁区系与核心。② 日高铁流量表现为沿京沪高铁“廊道型”向东西两侧递减弱化的“非对称性”格局,形成京沪、京广、杭福深相串联的高铁大三角主骨架;高铁中心要素也呈现沿京沪、京广、沪昆、杭福深等向线路两侧不规则递减格局,“廊道效应”显著。③ 胡焕庸线东南侧城市对高铁要素掌控能力大于西北侧,省会或区域中心城市多为高铁通达服务“中介”,一线城市高铁空间溢出效应有向二、三线城市过渡态势。

This paper studied the spatial structure, pattern, and characteristics of China's high-speed railway (HSR) network. The paper first built a daily origin-destination (O-D) HSR flow matrix consisting of 180*180 cities to evaluate the daily HSR flow of China. Then by analyzing the network density, four kinds of centralities, core/periphery structure and cohesive subgroups using the network analysis software, i.e., University of California at Irvine Network (UCINET), this paper displayed the structure and characteristics of China's HSR network. Finally, the global trend analysis and spatial interpolation function of geographic information system (GIS) were used to simulate the pattern of the daily HSR flow and four kinds of centralities in China and to reveal the characteristics and the differentiation of their spatial distribution. The results are as follows. First, spatially, the HSR network of China is loosely organized. The HSR network density of different regions differs greatly as such: eastern China> central China> northeastern China> western China. Particularly, the HSR network density of the Yangtze River Delta is higher than that of other region in China. This phenomenon shows the imbalanced and uncoordinated development of China's current HSR network. The HSR cliques and cores of eastern China, central China, northeastern China and western China are different. Second, by analyzing the daily HSR flow, we find that the flow of Beijing-Shanghai HSR line which has developed into the main "corridor" of China's HSR flow is much higher than that of the rest lines. However, its west and east sides have shown an asymmetric reduction trend. Beijing-Shanghai HSR line, Beijing-Guangzhou HSR line and Hangzhou-Fuzhou-Shenzhen HSR line are the nation's HSR center-lines, as they have the highest daily HSR flow. These three lines have developed into a triangle pattern, which is the basis of China's HSR spatial structure. The spatial pattern of the flows of the key urban elements, such as the population and industries, has been affected by the HSR network. These key elements of both sides of the Beijing-Shanghai HSR, Beijing-Guangzhou HSR, Shanghai-Kunming HSR, Hangzhou-Fuzhou-Shenzhen HSR lines have an asymmetric reduction trend, which shows the strong influence of the "corridor". Third, key elements related to HSR such as population and industries of the cities located to the southeast of the Hu Huanyong Line are higher than those of the cities to the northwest of the line in China. Beijing, Guangzhou, Chengdu, Chongqing, Shenzhen, Zhengzhou, Shijiazhuang, Nanjing and Shanghai are the national important HSR accessibility intermediary cities. These cities, together with other provincial capitals and regional central cities, have spatially developed into multiple service centers of China. Besides, the spatial spillover effects based on the HSR accessibility have been spilled from the first-tier developed cities to the second-tier or third-tier cities. The HSR development and its accessibility have brought potential agglomeration chances to second-tier or third-tier cities.

随着中国城镇化发展的转型,测度城镇化过程中人口、土地和经济三者发展的耦合协调关系,探索其演化过程的时空动态规律,已成为人文地理学研究新型城镇化的重要科学问题。通过构建耦合协调度模型,在测度近16年来长三角地区城镇化进程中各子系统的协调发展水平的基础上,运用空间变差函数,LISA时空跃迁等方法,分析长三角地区城镇化耦合协调的交互过程,探索其城镇化协调空间集聚的形成机制。结果表明：① 伴随长三角地区城镇化水平的显著提升,“人口、土地和经济”总体和两两耦合协调度演化均呈稳步提升的趋同现象;② 长三角地区城镇化耦合协调度空间集聚程度逐年增强,空间关联作用范围不断扩大,形成了“一极独大、三角核心、周边低平”的空间形态;③ 从各个城市的城镇化耦合水平跃迁路径来看,大多呈协同增长态势,表明城市的整体耦合协调度具有明显的路径依赖和空间锁定特征;④ 长三角地区城镇化耦合协调水平从稳定和均衡→极化集聚状态的演变动力主要来自于土地-经济的交互作用,而从极化→均衡状态的演变动力更多地来自于人口-土地的交互作用。城镇化协调度的交互过程及机制研究为新型城镇化发展和长三角城市群构建提供了理论依据和调控方向。

With the transformation of China's urbanization, how to measure the coupling and coordination relationship between population, land and economy in the process of urbanization, and explore the temporal and spatial dynamics of its evolution process, has become an important scientific issue in the study of new urbanization in human geography. By constructing the model of coupling coordination degree, based on the coordinated development level of each subsystem in the process of urbanization in the Yangtze River Delta in the past 16 years, this paper analyzes the interaction process of urbanization coupling coordination, and explores the coupling mechanism of the formation of urbanization coordination space agglomeration in the study region by using spatial variogram, LISA time-space transition and other methods. The results show that: (1) with the remarkable improvement of population, land and economic urbanization level in the region, the evolution of the overall and the coupling coordination of population-land urbanization, land-economy urbanization and population-economy urbanization degree shows a steady convergence phenomenon; (2) the spatial agglomeration degree of the coupling coordination degree of urbanization is increasing year by year, and the scope of spatial correlation has been expanding continuously, basically forming a spatial pattern of "one pole alone, triangle core, peripheral low-level"; (3) from the perspective of the urbanization coupling level transition path of each city, most of the cities show a synergistic growth trend, indicating that the overall coupling coordination degree has obvious path dependence and space locking characteristics; (4) the evolution of urbanization coupling coordination level from the stability and equilibrium to polarization agglomeration state mainly comes from the interaction of land-economy, and the evolutionary power from polarization to equilibrium state comes more from population-land interaction. The study of the interaction process and mechanism of urbanization coordination provides a theoretical basis and direction for the construction and coordinated development of the Yangtze River Delta urban agglomeration.

系统回顾西方尺度理论,尤其是尺度生产（尺度重构与尺度政治）理论,借此阐释中国城市区域治理形成的尺度逻辑。研究发现,中国城市区域包括城市群与都市区2个地理尺度；治理尺度是以行政权力为核心,形成自上而下的行政权力金字塔；治理尺度的动态重配并与地理尺度相耦合的过程是中国城市区域治理的尺度建构的本质；改革开放后,中国宏观政治经济在“去中心化-再中心化”过程中持续动态调整；中国城市区域的产生是国家空间选择性的结果,来克服以城市为基础的资本积累模式的体制危机；城市群治理以柔性尺度重构为主,都市区治理以刚性尺度重构为主；城市区域内部产生复杂的多主体间的尺度博弈。

This article aims to systematically demonstrate the evolution and development of scale theory and its features in different periods. The perspective of scale theory is then used to elaborate the formation of city-regional governance in China. A conceptual framework is proposed in this article. Four major conclusions are presented as follows. First, the geographical scale of China’s city-region consists of two modalities, namely, metropolitan area and urban agglomeration. The governing scale of China’s city-region is essentially constituted by administrative powers, all of which made up a top-down power matrix. The restructuring of governing scale oriented geographical scale of city-region is the nature of rescaling of China’s city-regional governance. This restructuring process is central to understand the rationale of China’s city regional governance. Second, the macro socioeconomic development in China has manifested as the dynamic adjustment process between decentralization and recentralization. The rise of city-regional governance in China is the outcome of state spatial selectivity oriented city-regions to overcome the crises brought by the conventional city-based accumulation regime. Third, the governance of urban agglomeration is featured by the soft rescaling. Correspondingly, the governance of metropolitan area is characterized by rigid rescaling. This rigid rescaling has embodied as the reconfiguration of various jurisdictions oriented a new administrative relation. Last but not the least, there are complicated games between multiple actors at the city-region scale. To sum up, China’s city-regional governance reflects the changing political economy of regional development in post-reform era.
