Overcoming barriers to institutional integration in European second-tier urban regions

Within the debates about the socio-economic advantages of cohesive urban regions, several barriers to institutional integration are said to exist, especially when a metropolitan government is absent and integration relies on inter-municipal cooperation. Some barriers are associated with different urban region structures, such as the asymmetric power relations and sociocultural contrasts between municipalities in systems with dominant core cities, or the lack of a leading city to overcome fragmentation and provide a shared identity in polycentric urban regions (PURs). This paper investigates whether urban regions formed around second-tier cities, whose features depart from both dominant core and PUR models, are able to mitigate these barriers when pursuing integration strategies. The analysis relies on interviews with municipal leaders in three representative European case studies, examining how they perceive the barriers to inter-municipal relations in second-tier urban regions. The findings show that perceptions vary not only between regions, with the three cases following different trajectories of integration, but also within regions, according to the geographical and socio-economic context of municipalities and the legacy of past relations. In general, barriers to integration are not minimized without explicit efforts to rebalance power relations, approach political cultures, mobilize core city leadership and develop a metropolitan identity.

南京都市圈空间相互作用时空演变分析

利用改进引力模型并结合GIS 方法,分析2000 年以来南京都市圈县域尺度空间相互作用的时空演变,探讨圈域发展的问题与对策。结论如下：南京都市圈县市空间联系强度不断增强,南京主城与其它县市相互作用强度最高,其次为沿江各县市间、地级市主城区与其郊县间,南京、扬州、镇江、马鞍山等所辖县市间出现了联系强度较高的网络,有一体化发展趋势;历年县市潜力值都由最高峰的南京主城区为中心向四周递减,呈圈层式结构,在向外扩展过程中存在空间变异性,高潜力区沿江伸展,随着圈域内其它地区的发展,单一核心的结构开始发生变化;最后总结都市圈发展过程,提出圈域一体化发展的政策、交通、产业措施。     

差异分权与多元碎化:大都市边缘地区城镇化空间模式研究——基于武汉市蔡甸区的实证

大都市边缘地区是大都市经济增长与空间拓展的主要地域,也是分权化治理最为复杂的区域。大都市边缘地区往往针对不同主体采取不同模式的分权化来调整其空间治理结构以适应发展需求。本文构建从分权化治理到城镇化空间的逻辑框架,从大都市边缘地区"差异分权"的空间治理格局入手,落脚在"多元碎化"的城镇化空间模式上,进而对从空间治理的"差异分权"到城镇化空间模式的"多元碎化"间的制度逻辑进行了解析,认为差异分权格局是当前大都市区边缘地区城镇化空间模式多元碎化的直接诱因,因此新型城镇化迫切需要从治理结构上予以破解。     

The Study of Local Public Economies: Multi‐organizational,Multi‐level Institutional Analysis and Development

One important extension of the IAD framework has been to the study of local public economies. These are multi‐organizational, multi‐level arrangements defined as the set of governmental jurisdictions, public and nonprofit agencies, and private firms that interact in various patterns to provide and produce public goods and services within a specific locality or region. Commonly, the localities or regions studied from this perspective have been U.S. metropolitan areas, often defined as a central city and its surrounding or adjoining county. Localities can be delineated, however, on various terms, and in the IAD framework, it is the geo‐physical nature of a locality that, in substantial part, drives the analysis. One of the strengths of the approach is its capacity to explain local variations in public organization as a function of the geo‐physical diversity of localities, while at the same time developing empirical generalizations and normative principles that apply across diverse regions. What, for example, might the organization and governance of a complex metropolitan area have in common with the organization and governance of a complex protected area, such as the greater Yellowstone eco‐region or the Adirondack Park? Construing both sorts of regions as local public economies can enhance our overall understanding of public organization at the same time that it permits a more nuanced understanding of diverse localities. Such work contributes to the ongoing IAD project of “understanding institutional diversity.”     

Restructuring of Beijing's Social Space

Four China-, U.S.-, and UK-based senior specialists on the urban geography of Beijing team up to present the results of their investigation of the change in the city's social landscape on the basis of restricted subdistrict-level data covering the period from 1982 to 2000. Adopting a factor ecology approach, the authors seek to identify the extent to which factors that shape urban social landscapes in Western countries have played a role in Beijing during a period of economic transition (e.g., from administrative toward market allocation of housing). Similarly, they investigate the relative strength of processes of social differentiation vis-à-vis mixing accruing from the restructuring of Beijing's physical space (e.g., housing cost differentiation and accelerated in-migration that lead to the emergence of concentrated areas inhabited by migrants and/or minorities, and of relatively low density suburbs) revealed by the 2000 Census. The paper includes a section on developments since 2000, citing data (through 2006) on population, scarcity of affordable housing, traffic congestion, and industrial and residential relocation, relating in part to the forthcoming Olympic Games in 2008.

广州大都市外围地区二元发展的矛盾及治理

结合广州案例选择界定研究范围,从空间形态、产业发展、土地利用、规划管理多方面分析大都市外围地区二元发展矛盾与特征,认为该地区承担了主城"自上而下"的空间外拓和外围撤市(县)设区后"自下而上"式的城镇蔓延。进而运用区域治理理论分析,指出其根源在于双轨城市化路径依赖下,现有规划编制与实施体系难以协调当前城乡二元土地管理制度下不同团体的利益冲突,认为广州应当从传统集权管理转向治理理念的协作方式,由此提出建立"发展需求管理、土地开发共同决策、发展利益分享"三个机制的对策研究。     

武汉都市圈经济社会要素流的空间分析

都市圈城际经济联系与相互作用空间表现形式为城市间、城市-区域间的人流、物流、信息流、资金流、技术流等经济社会要素流。基于城际功能集散效应影响量建立城市流模型:F=NE,揭示出:武汉都市圈各中心城市经济社会要素流强度空间差异明显,对外经济联系呈现显著规模等级分布,空间结构上已经形成以武汉为中心的"鞍形"圈层结构。通过统计数据,利用SPSS统计软件,从实证角度分析得出:武汉成为圈域经济社会要素流集散中心,城际经济社会要素流不同程度表现出以武汉为中心的"等级放射状"空间格局。
