我国城市规模分布Pareto指数测算及影响因素分析

本文用OLS方法测算我国各省、三大区域以及全国的城市人口规模分布和经济规模分布Pareto指数(1997年、2000年和2003年),对Pareto指数进行跨区域和跨时间的对比分析,并实证分析我国城市规模分布的影响因素。分析表明,我国的城市规模分布显著地服从Pareto分布,并具有明显的结构性特征。工业化、产业结构以及运输能力对城市人口规模分布具有显著影响,而工业化和运输能力则是影响城市经济规模分布的重要因素。     

嘉兴市区现行拆迁安置形式亟待改进

长期以来,嘉兴市区拆迁安置一直采用以“拆一还一”为原则的产权调换形式,虽然这种拆迁安置形式对社会经济发展、城市基础设施建设、市区规模扩大以及房地产市场繁荣曾起到过巨大的促进作用。但是随着国家对房地产业一系列宏观调控政策的出台,市区房地产市场已经出现供大于求,观望气氛浓厚,空置面积大幅增加等不利局面。为了促进市区房地产市场的可持续发展,必须改变现行拆迁安置形式,以货币补偿来替代原有的产权调换。

Natural resource accounting for Indian states — Illustrating the case of forest resources

Our main objective is to set out and apply a SEEA-based methodology to reflect the true value of forest resources in India's national and state accounts. We establish that a “top-down” approach using available national databases is both feasible and desirable from a policy perspective. In this paper, we address four components of value creation in forests: timber production, carbon storage, fuelwood usage, and the harvesting of non-timber forest products. The results of our analysis suggest that prevailing measures of national income in India underestimate the contribution of forests to income. The income accounts of the Northeastern states in particular are significantly understated by these traditional (GDP/GSDP) measures. We are also able to identify some states which performed poorly in the context of our sustainability framework, reflecting natural capital losses due to degradation and deforestation. Our results highlight the need to integrate natural resource accounting into the national accounting framework in order to generate appropriate signals for sustainable forest management and for the conservation of forest resources which are widely used by the poor in India, as well as being significant stores of national wealth.     

经济全球化进程中城市群发展的制度创新

从我国城市群目前的发展现状来看,影响城市群发展的主要因素是制度障碍:城市群跨界需求与行政区分割的障碍、缺乏城市群一体化发展的协调政策、没有形成有效的空间管理机制。因此,制度创新应是发展我国城市群的关键所在,重点是在法律制度、空间规划和管理制度等方面的创新。     

Coupling relationship between environment and economyof metropolis：a case study of Chongqing, China

City is a coupling system of economy, society and environment. The urban environment is a supporting systemto the sustainable development of city. Taking the urban area of Chongqing as an example, this paper establishes theindicator system for assessment of the coordination between urban environment and economy according to the resultfrom principal component analyses by software SPSS11.0. Meanwhile, the weight was assigned for each indicator basedon the load of the first proper principal components. Through computation of the coordinated development model set upaccording to the knowledge of statistics, the paper draws the conclusion that the situation of the coordination betweenenvironment and economy in Chongqing developed well from 1996 to 2004. Finally, countermeasures for the coordina-tion in the coming years are proposed.

Impacts of an EC carbon/energy tax and deregulating thermal power supply on CO2, SO2 and NOx emissions

Emission of CO₂, SO₂ and NO_x are all closely linked to the burning of fossil fuels. Here we report on simulations done by linking a Sectoral European Energy Model (SEEM), covering energy demand in nine Western European countries, with the emission-transport-deposition model RAINS developed by IIASA. The study analyses emissions of CO₂, SO₂ and NO_x, deposition of sulphur and nitrogen and the extent of areas where the critical load for sulphur is exceeded in year 2000 under four different energy scenarios. Two different sets of future behavioural patterns for the thermal electric power production sector are considered. In one regime, called the plan-efficient regime, the sector is assumed to follow official plans with regard to investment in new capacity. In the other regime, called the cost-efficient regime, the thermal power sector is assumed to behave in a cost minimizing manner. The effects of the proposed EC carbon/energy tax are studied under both regimes, giving rise to altogether four scenarios.In both regimes the effect of the EC tax is to reduce emissions by between 6 and 10 per cent in year 2000 relative to the scenarios without the tax. A change of regime, from the regulated, plan-efficient regime to the market-based, cost-efficient regime, will, by itself, reduce emissions of CO₂ and NO_x by approximately 3 per cent, while SO₂ emissions are reduced by 13 per cent. The EC tax will reduce sulphur deposition by more than 5 per cent in the nine model countries under the plan-efficient regime. A change of regime further reduces the total deposition by 9 per cent. The area where depositions exceed the critical load is reduced by approximately 6 per cent in year 2000 by the tax in both regimes. Changing from the plan-efficient to the cost-efficient regime has a similar impact.Although the emission reductions due to the EC tax may seem modest, they are shown to have a sizeable effect on the technological abatement costs of reaching targets like those prescribed in the Sofia protocol on the stabilisation of NO_x emissions, and the Helsinki protocol on SO₂ emission reductions. This is part of what can be considered to be secondary benefits of the EC carbon/energy tax.     

北京城市办公业发展与城市变化阶段分析

办公业发展作为城市经济转型的组成部分,在北京城市变化中经历了4个阶段:(1)变消费城市为生产城市——办公业萌芽期。新中国成立后至改革开放前,北京城市大力发展工业,变消费城市为生产城市。这一时期由于政治上的原因,外商驻京机构很少;而国内金融、保险、房地产、信息行业基本处于萌芽阶段。因而,该时期无真正意义上的办公业。(2)现代化城市——办公业起步期。改革开放至20世纪80年代中后期,北京向现代化城市迈进,商务管理职能为主体的办公业开始萌芽,城市经济结构发生了变化,第三产业中生产性服务业开始兴起。(3)国际化大都市——办公业起飞期。从20世纪90年代中后期至21世纪早期,北京开始向国际化大都市靠近,相对形成了几个办公区域,如CBD商务办公区域、中关村高科技办公区域、复兴门金融办公区域等。生产性服务业占据主导地位。(4)现代化国际城市-办公业飞速发展期。2008年奥运申办成功后,北京城市发展又处于一个转型期,以公司办公为核心的办公业空间集聚使北京城市发生新的变化。
