随着城市经济的快速增长,北京市郊区化(Suburbanization)进程发展迅速。与西方世界郊区化主要源于人们迁往郊区逃避日趋严重的大城市问题不同,北京的郊区化主要是因为郊区房价相对便宜,穷人在城市内买不起房子才在郊区买房子。所以就出现西方社会穷人住市内,富人住郊区;而中国是富人住市内,穷人住郊区的现象。这种不同导致中国的郊区化处于十分尴尬的处境--富人以巨资购买市内大面积房屋,大量占有市内十分稀缺的资源,却不见得能够拥有一个静谧的环境;穷人无钱供车,却要每 相似文献

随着北京房地产市场逐渐步入成熟与稳定的发展阶段,郊区住宅越来越被人们所关注,显现出勃勃的生机,具有广阔的发展前景。 郊区化与郊区住宅 1.郊区化 按照北京大学经济地理学家周一星教授的观点,郊区化简单地说,就是人口、就业岗位和服务业从大城市中心向郊区迁移的一种分散化的过程。 从上世纪20年代以来,西方发达国家的大城市发生了一次又一次从城 相似文献

中外城市郊区化的比较 总被引:11,自引:1,他引:10
城市郊区化(简称郊区化)是城市化过程中的一个发展阶段,它的到来标志着城市由集聚式发展转变为扩散式发展。本世纪20年代西方发达国家就已出现了郊区化现象。我国目前是否出现了郊区化现象,是否进入了郊区化发展阶段,许多学者对此意见不一。周一星等人认为,我国大城市,如北京、上海、沈阳、大连出现了郊区化现象,并作了实证研究。[1]另外一些学者认为,郊区化是和扩散发展阶段联系在一起的,而我国城市尚处于集聚发展阶段,我国城市并没有出现中心区的衰退现象,因此我国没有出现郊区化。[2]还有相当多的学者认为,我国城市… 相似文献

认为不同规模的居民点构成中心地等级体系,人口规模与密度仅能提高中心地的市场规模,而不能提升市场的功能等级;区域交通条件的改善在城市化阶段有利于高级中心地的发展,在郊区化与逆城市化阶段则有利于低级中心地的复兴,产生大城市的衰退;世界经济一体化使得小城市可以有大市场,城市功能等级不再取决于人口规模,而是城市竞争力。 相似文献

中国在改革开放后以产业飞地为初始模式推动的郊区化进程与北美的郊区化进程具有不同的特征。阐述了中国城市的飞地郊区化的特征,并研究其背后的动力因素。首先对产业飞地和飞地郊区化的特征,及其塑造多中心城市空间的动力进行了阐述。其次,以苏州市区为案例,分析了苏州如何通过飞地城市化推进郊区化发展并促进多中心城市结构的形成。研究认为,与北美经典郊区化理论不同,飞地模式的郊区化具有外生性特征。在外来力量和“创业主义”政府的共同推动下,“飞地郊区”逐渐成为城市的新城或新中心,推动了城市空间结构向多中心转变。 相似文献

基于用地效率分析的城市区域空间结构极化模型及空间发展战略 总被引:2,自引:0,他引:2
不同规模的城市其用地效率具有一定的差异性.本文通过对中国660余个不同规模城市的用地效率分析,在总结和分析了传统城市区域空间结构基本理论和模型的基础上,提出基于城市用地效率分析的城市区域空间结构极化模型.通过理论与实证分析表明,城市发展的方向一极是大型化,发展成为特大城市或超大城市(人口100万-400万);另一极是小... 相似文献

The patterns of spatial socioeconomic segregation in Latin American cities are changing rapidly as a result of suburbanization and metropolization. However, the political consequences of these urban spatial processes are not well understood. This article uses Orfield's framework of analysis to test the hypothesis that spatial segregation at the metropolitan level is driving political polarization between Latin American cities and their suburbs. With Bogotá as a testing ground, we look for evidence that the mechanisms described by Orfield are at play. We conclude that metropolitan spatial segregation does not drive metropolitan politics in Bogotá and explore some of the theoretical implications thereof. 相似文献

This paper is an empirical study of effects of central city problems on population and employment suburbanization. It is widely believed that high crime, high taxes, and large minority groups in central cities are important causes of rapid suburbanization of U.S. metropolitan areas. A large set of density functions is estimated for population and employment in U.S. metropolitan areas in 1960 and 1970. Thus, relative central city and suburban measures of crime, taxes, etc., are used in an interactive model to explain population and employment suburbanization. It is found that only racial minorities have an effect on suburbanization. 相似文献

The aim of this article is to determine whether population suburbanization is occurring in Barcelona and, if so, how it is organized spatially. This issue is addressed through an analysis of the spatial structure of the population of the Barcelona Metropolitan Region and its evolution between 1991 and 2005. The ultimate aim is to determine whether there is a process of population suburbanization during these 15 years and, if this is the case, whether it arises according to a dispersed or a polycentric model. The results are consistent with a polycentric model for 1991 and 2005. However, this spatial structure is changing because of the process of suburbanization, which is affecting both the central business district and subcenters. During this same period, it is found that the role played by transport infrastructure in determining the spatial structure is becoming stronger. Without considering this latter result, it would appear that the dispersed model would best describe the next spatial stage. On the other hand, if the role played by transport infrastructure is taken into consideration, the next spatial stage would be an accessibility model in which population concentrates along freeways and highways. 相似文献

在中国诸多大中城市郊区化进程中,一个非常显著的现象是:高档和低档住宅的二元分立,从而破坏了人们居住空间的复合性及和谐性.造成这一现象的根本原因并非人们的"阶层"意识,而是城市郊区化的潜在思路:仅仅关照人们的居住,却没有关照人们的生活,人们的完整生活在郊区化过程中被割裂了.解决这一问题的出路是构建混合式社区,而其理论基础是新都市主义. 相似文献

近年来,我国城市空间结构的发展中出现新的趋势,引起了学者们的广泛关注。与以前相比,现有研究对大都市区和大都市连绵带这两种新兴城市空间形态的研究比较重视,郊区化的研究也更加深入。但是,在理论体系建设、中外比较研究、实证研究和多学科融合等方面,还有待于进一步的拓展。 相似文献

The previous literature has generally found that most Chinese cities were undersized in the 1990s. However, little is known about how urban agglomeration in China has evolved since the country began to experience much faster urbanization and deep marketization after 2000. Based on panel data of 281 cities between 2000 and 2013, our spatial panel data regression results show that the scale impact of city size on urban productivity appears to have an inverted U shape, and its effect will grow when the cities’ industrial structure becomes more dominated by the service sector. There are also significant spatial interactions and spatial heterogeneity of urban agglomeration among Chinese cities. Furthermore, we compute the optimal size for each city and find that most Chinese cities are still undersized in recent years. Based on our findings, we argue that the Chinese government should focus on promoting sufficient growth of medium sized cities in its new urbanization strategy. 相似文献
