《北京城市总体规划(2004年--2020年)》规定:今后北京市将按照“两轴-两带-多中心”的城市空间新格局,对北京城市功能和城市结构、城市布局、城市空间进行调整,对北京经济和社会发展重新定位和重新布局。
在“两带”上将建设11座新城,以吸纳城市新的产业和人口,以及分流中心区的功能。
规划新城包括亦庄、顺义、怀柔、大兴等11个将来的中心城市,其中确定了顺义、通州、亦庄等三个为重点新城,优先发展。将来市中心的人口要逐渐向新城转移,这些中心城市人口都在50万左右,其人口至少70%以上在当地就业。
预计:未来15年内,北京市将有90%的人口到郊区居住。其中通州中心城是规模最大的。而且计划北京市政府也将在条件成熟时迁往通州,形成新的市中心。
作为新城之一的通州,新城规划方案已经完成。近日有媒体报道,标准;降超过上海浦东。这引起社会各方面的广泛关注。 相似文献

北京能源消耗与经济发展分析报告 总被引:4,自引:0,他引:4
党的十六届五中全会明确提出把节约能源作为基本国策,要求到2010年,单位GDP能耗比“十五”期末降低20%左右。北京市根据自身发展特点,在全市“十一五”规划纲要中提出,到2010年全市万元GDP能耗下降15%。 相似文献

Cluster evolution and urban industrial dynamics in the transition from a planned to a socialist market economy: the case of Beijing 总被引:1,自引:0,他引:1
Cluster evolution and urban industrial dynamics in the transition from a planned to a socialist market economy: the case of Beijing. Spatial Economic Analysis. The transformation of the industrial structure of Beijing in the transition from a planned to a socialist market economy integrated into global markets is examined through the lens of cluster evolutions and life cycles in 1987–2007. Cluster emergence, decomposition, stabilization, upgrading, restructuring and disappearance are identified using exploratory factor analysis of input–output tables. These evolutions are interpreted in the light of the way in which backward and forward linkages provide channels of communication, new intermediate goods, new divisions of labour and new patterns of co-location, and are related to the changing industrial geography of Beijing. 相似文献

构建城市绿色海绵——生态雨洪调蓄系统规划研究 总被引:14,自引:0,他引:14
针对北京市面临的内涝水患和水资源短缺双重矛盾,融合国内外最新的生态雨洪管理理念,提出以绿地和水系为主体,构建城市"绿色海绵",转变依赖大规模工程设施和管网建设的传统思路,探索雨水资源化的新型景观途径。以北京市亦庄经济技术开发区南拓片区为例,具体研究"绿色海绵"构建的技术方案,规划三级生态雨洪调蓄系统,通过对雨水径流进行源头控制和就地入渗,实现城市防涝、水源涵养和水景营造的多重效益。 相似文献

The presenft paper develops a structural decomposition analysis with cumulative product lifetime distributions to estimate the effects of both product lifetime shifts and energy efficiency changes on the embodied energy consumptions. The empirical analysis focuses on automobile use (ordinary passenger vehicles, small passenger vehicles, and light passenger vehicles) in Japan during the period 1990–2000. It reveals that the lifetime extension of existing old vehicles during the study period was more beneficial to the environment than purchasing new passenger vehicles with a relatively high fuel economy, because the lifetime extension empirically contributed to reducing the embodied energy consumption at the production and end-use stages. We also found that the energy-saving impact of a one-year lifetime extension was approximately 1.3 times larger than that of the most significant technological improvement in the electric power generation sector. 相似文献

我国城镇居民平均消费倾向与收入分配状况关系的实证研究 总被引:21,自引:0,他引:21
中国的有效需求不足现象近年来成为一个被普遍关注的问题,而居民消费需求不足更是成为关注的焦点。本文在前人研究的基础上,从标准的消费者预期效用最大化模型出发,推导出中国城镇居民的个体"短视"消费模型和总量消费模型;运用我国1985~2004年城镇居民消费、收入及其他相关数据,通过误差修正模型和对数线性模型分别对数据进行了计量分析,发现在我国现阶段,城镇居民收入分配差距的扩大引起了居民平均消费倾向的减小,且其长期影响尤为显著。在对计量结果进行分析的基础上,本文给出了若干政策建议。 相似文献

In this paper, we develop a new approach that combines the spectral clustering method and input–output analysis to detect environmentally important supply chain clusters. The newly developed method was applied to automobile manufacturing in Japan, and major clusters with high energy intensities in the automobile supply chain were identified. This paper proposes that the car manufacturers will be able to regularly publish their life-cycle assessment reports with a focus on the indirect energy consumptions within the critical supply chains and request key auto-part manufacturers in the cluster to reduce the indirect consumptions through the relevant supply chain engagement. 相似文献

论北京城市副中心建设 总被引:1,自引:0,他引:1
北京"单中心、同心圆式"的城市空间格局,使城市功能过度集中于中心城区,给中心城区造成了严重的交通拥堵和环境压力,限制了北京综合承栽能力的提升,影响到北京的可持续发展.东京、巴黎等都通过建设"副中心"解决了城市发展中的空间矛盾.北京应借鉴国际大都市发展经验,启动建设京西副中心、通州-亦庄副中心和顺义副中心,打造分散疏解中心区功能的重要空间栽体,解决北京城市发展中的空间结构矛盾. 相似文献

Mumbai forms the décor to an interesting set of relationships among economic liberalization, globalization, class restructuring and an unprecedented housing construction boom. The much talked about new Indian middle class is primarily an urban phenomenon and seems nowhere more salient than in India’s commercial capital and largest city. This article seeks to undo some of the mysteries that surround the new middle class: how it can be empirically defined, whether and how it is growing, how class restructuring in Mumbai conforms (or not) to Western arguments about social polarization, and how any such class restructuring can best be explained. The empirical analysis employs existing data from various sources on income and consumption in Mumbai (and India at large) and reports on selected findings from a recent survey by the author on housing, class and upward mobility among households in newly constructed homes in Greater Mumbai. Data on the distribution of household incomes show that the upper‐middle income classes have grown relative to the total, that the lower‐middle income classes have shrunk, and that the ranks of the poor have expanded slightly. Survey data among new home buyers in Mumbai suggest little upward mobility. Discourse about the ‘new middle class’ tends to focus on consumption rather than income and additional findings indicate that much of the growth in consumption is credit‐based. 相似文献

"简政强镇"改革,使乡镇经济社会管理职能由"权小责大"向"权责一致"转变,已经取得了实质性的进展。但这一改革仍面临着诸多的困境。因此,必须从形成改革共识、理顺行政体制、转变职能定位、保障执法权威以及加强权力监管等方面构建"简政强镇"改革的实现机制,才能从体制和法制上保障改革的顺利进行。 相似文献
