This study investigates whether or not income stratification by place has widened within the Tokyo Metropolitan Region (TMR) over the past 30 years. Its analysis shows that although income stratification among the TMR's 228 municipalities has expanded noticeably since 1980, it has remained far less severe than that in America's three largest metropolitan regions, New York, Los Angeles, and Chicago. Declining regional industrial employment, expanding national income inequality, falling land prices in the region's core, and the entrepreneurial waterfront redevelopment policies of the Tokyo Metropolitan Government (TMG) were some of the catalysts that propelled this rise in stratification in the TMR. Conversely, the region's unique racial-ethnic context and the municipal merger policies of Japanese Government were two of the factors keeping its level of income inequality far below that of America's largest urban regions. These findings support the position of Nested City theorists, who claim that embedded forces remain the most decisive determinants of growth trajectories in the TMR. 相似文献

全球城市技术合作网络的拓扑结构特征与空间格局 总被引:6,自引:3,他引:3
采用2015年PCT专利数据,构建全球城市技术合作网络。利用复杂网络分析和空间分析方法研究全球城市技术合作网络的拓扑结构与空间分布。研究发现:拓扑结构上,全球城市技术合作网络的密度较低,城市节点对外联系强度极不均衡。网络为无标度网络,社团结构明显。空间格局上,全球技术合作网络中城市节点的专利总量和对外联系次数都呈一定区域性,城市节点主要通过全球知识网络获取知识。巴黎和东京无论是专利产出还是合作数量都具有领先优势,对外联系紧密,枢纽性强。网络中城市节点度中心性的空间分布上与专利产出的分布格局基本相同,而介数中心性的分布格局更为集中。 相似文献

以山东省临沂市东风东关片区改造为例,将海绵城市建设要求融入到园林景观建设中。通过对临沂当地降雨量的分析,制定区域降雨控制管理目标,采取了屋顶绿化、透水铺装、下凹式绿地、植草沟、渗井渗管、车库顶板处理、雨水回收利用系统和植物绿化等措施。雨水回收利用系统工程完成后,通过夏季的几场大到暴雨的检验,实现降雨后片区道路雨水下渗明显、无积水,基本达到规划设计的目标要求,该方法将有助于海绵城市在临沂市的推广应用。 相似文献

本文首先回顾了价值链与全球生产系统的研究进展,结合跨国公司最新发展趋势对全球生产系统特征进行了总结;其次以改革开放以来上海对外贸易结构的改变,描述了90年代以来上海在全球生产系统分工中的变化,认为出口产品结构的转型并没有真正改变上海在国际劳动分工中处于低端环节的地位;最后就上海建设世界城市的差距与优势进行了总结,提出全球化发展的外部力量和地方化响应的内部力量将是上海发展世界城市的两个重要驱动力。 相似文献

2014、2015年教育部接连发文要求落实“免试就近入学”政策,由此公立初小的入学资格与住房紧密挂钩。在此背景下,初小教育资源如何影响住宅价格,并带来怎样的城市社会空间变化是有意义的科学问题。论文基于安居客、链家、百度开放平台及问卷访谈等数据,综合运用特征价格模型、地理加权回归模型等方法,以武汉市武昌区为实证区域,探索学区对住宅价格的真实影响,并尝试从“空间生产”入手,探究学区引发的城市社会空间重构。研究发现:① 学区特征对住宅价格的影响已超过传统区位、建筑、邻里特征等的影响;② 学区房提供了资本由二级循环进入三级循环的便利路径,形成了学区空间生产与社会空间新分层的宏观基础;③ 微观层面,对优质学区的争夺产生了“学区人”和“学区空间”,进而出现学区飞地,对传统城市社会空间产生影响;④ 不同于“单位人”与“社区人”,“学区人”并不主要依靠职业或收入划分,而是因相似的家庭生命周期发生关联。 相似文献

Despite Tokyo’s size and position in the global urban system, studies of its employment distribution have been few. This research identified the locations and ranks of the employment centers in the entire metropolitan region and analyzed the characteristics of the economic sectors in those centers by using fine scale economic census data. Minimum sizes for a center were explored at a range from as small as 250 by 250 m to 3,000 by 3,000 m, and the Local Indicators of Spatial Association technique was utilized for detecting centers in different ranks. The results showed that, from a regional view, Tokyo has a typical monocentric or concentric spatial structure. However, from a fine scale view, the distribution was revealed to be expanding along the railroads to the suburbs, and both the main central business district and the suburbs are polycentric. Through this research, the authors argue that rather than using thresholds of total employment and minimum densities as seen in the previous studies, centers can be effectively detected by comparing with the surrounding areas at different scales. This “scale-view” approach of center identification may provide a new perspective to other metropolitan regions of the world as well. 相似文献

优质学区社区作为当前最为活跃的城市社会空间之一,深刻影响着城市社会空间的重构与分异。基于邻里交往的视角,利用针对南京市银城小学学区居民的问卷调查,分析了优质学区社区的邻里交往特征,据此揭示其社会-空间效应。结果表明:(1)作为典型的名校学区社区,银城小学学区的邻里交往表现出低相识度、浅层次、网络化、低认同度、以教育为中心的特点。(2)透过邻里交往讨论优质学区社区的社会-空间特征:居住和交往空间日益成为物质空壳,交往主体和行为成为没有内容和情感支持的“形式”,流动性加剧又引致社会认同锁定在低水平而难以提升。(3)根本上,优质学区社区的社会-空间凸显分离甚至对立的趋势,不断催生学区社区的异化。 相似文献

The ‘global city’ concept has captured the attention of geographers and other social scientists. Research focuses predominantly on capital mobility and the important managerial role exerted by cities in the ‘developed’ realm (i.e., New York, London, Tokyo). The mobility of labor is also important and yet has been neither critically conceptualized nor sufficiently analyzed in existing studies of global cities. Using the Philippines as a case study, I examine 1) how global circuits of labor are socially organized, and 2) the extent to which this social organization is spatially concentrated in Manila. In so doing, I reaffirm the critical role played by Third World cities as global cities. 相似文献
