The aggregate effects of a variety of impacts generated by motor transport on the natural environment in the Upper Oka River basin are examined (through factor analysis) and maps of roadside pollution intensity are generated. The two factors identified, representing the effects of higher-order and local roads, respectively, provide a basis for regionalization of the Upper Oka basin according to the impacts generated by automobile traffic. The pattern of regional impacts identified, in turn, provides the basis for policy recommendations on how to reduce the level of roadside pollution and minimize other negative environmental impacts of road transport (translated by Jay K. Mitchell, PlanEcon, Inc., Washington, DC 20005). 相似文献

本文从中国经济增长两个阶段的不同特点入手,分析了90年代中期以后中国大量引进外资的深层次原因。采用制造业增加值占GDP的比重作为衡量中国工业化进展程度的指标对整个90年代中国工业化的进程进行了实证分析,结果发现,中国的工业化从90年代中期以来实际上长期处于低速徘徊的阶段。大量引进外资导致中国工业化过程中存在两个明显的"替代效应",一是"外资替代效应",二是"弱质替代强质"现象。两个"替代效应"对中国工业化和经济结构变化的影响是极为深刻的。 相似文献

ABSTRACT The index proposed by Ellison and Glaeser (1997) is now well established as the preferred method for measuring the localization of economic activity. In this paper we develop an alternative localization measure that is consistent with the theoretical framework originally proposed by Ellison and Glaeser. Our measure follows directly from the Random Utility (Profit) Maximization (RUM) location decision model. Because the distributional assumptions in our model are fully compatible with RUM, we are able to offer a more efficient measure of industry clustering. 相似文献

THE IMPACT OF ECONOMIC OPPORTUNITY, AMENITIES AND FISCAL FACTORS ON AGE-SPECIFIC MIGRATION RATES 总被引:5,自引:0,他引:5
ABSTRACT. Migration models have considered several different categories of determinants, including economic opportunities, amenities, and state and local fiscal factors. Migration has also been shown to depend on the individual's position in the life cycle. This paper represents a first attempt to integrate all three categories of determinants of migration into a life-cycle framework. Empirical findings generated from a countrywide model of white male migration, over the period 1970 to 1980, reveal that all three types of determinants are important. Specifically, economic opportunities are most influential for males during their working years. Amenities are also found to follow a life-cycle pattern with older migrants more attracted to amenable locations than their younger cohorts. Finally, state income and death taxes display life-cycle effects; working males in their peak earning years are detracted by high income taxes while all migrants aged 55 to 69 avoid counties in states with high inheritance and estate taxes. 相似文献

The dean of Moscow University's Geography Faculty, a physical geographer, takes issue with alarmist predictions of an environmental deterioration and contends that modern technology will find ways of protecting the environment against pollution. Modern cities, which are among the principal sources of pollution, are taking steps to preserve the urban environment by the increased planting of greenery and the systematic installation of waste treatment facilities for noxious industries. Natural processes are found to have a surprising ability to adapt themselves to new conditions and thus play a more important role than generally assumed in restoring the chemical equilibrium of the natural environment. The cost of environmental protection is undoubtedly rising, and an effort at arms limitation is urged to make the necessary money available. The threat of an exhaustion of energy sources is discounted on the ground that new nonpolluting sources of energy are likely to be developed as fossil fuels approach depletion. 相似文献

中国古代人与自然环境关系思想透视 总被引:1,自引:0,他引:1
在人类正面临生存环境的严重挑战的今天,中国古代人地关系思想的科学价值与现实意义受到中西方学者的高度重视。中国古代人与自然环境关系思想的突出特色在于,承认自然环境限制作用,强调在此前提下主动地适应自然环境,从以人为本的基点出发去保护自然环境、追求人与自然环境的和谐。这种人与自然环境相协调的人地观是中华民族在长期与开发利用自然环境的生产和生活实践过程中形成的,是中华民族悠久的文化传统的重要组成部分,也是中华文明得以延续的一个重要因素,它对现今社会的发展仍具有现实意义。 相似文献

On the basis of early chronicles, statutes, and maps, as well as toponyms, the author retraces the river routes and portages used by Novgorodian and Rostov-Suzdalian tribute collectors, traders, and soldiers travelling from the upper reaches of the Volga to the White Sea slope in the 12th-14th centuries. He also indirectly assesses the negative and positive impact of these waterways on the physical environment on the basis of artifacts and logic. (The translation was prepared by James R.

21世纪的太平洋——在政治、经济、军事上的重要性评价 总被引:1,自引:0,他引:1
太平洋是地球上最大的海洋,在环太平洋沿岸和浩瀚海洋中星罗棋布的岛屿上,分布着40个国家和一些尚未独立的地区,太平洋地区国家陆地面积占世界的46%,人口占世界的40%,但却拥有全球50%以上的GNP和近1/2的世界贸易总额。二次大战以后,太平洋地区的迅速崛起,引起国际舆论的广泛关注。21世纪是太平洋世纪,已日益被国际社会所公认。本文立足于政治军事地理及地缘政治学的基本理论,以21世纪是太平洋世纪的基本结论为出发点,从资源、经济、政治、军事等四个方面对太平洋在21世纪的重要性进行了系统地分析与评价。指出太平洋不仅是人类有待开发的巨大资源宝库和全球经济最富有活力的地区而且是21世纪全球地缘政治中心和地缘战略中心,是世界上各大国和大国集团矛盾的焦点,以及军费增长最快和军备最密集的地区。在今后相当长一段时期内,围绕太平洋地区控制权的争夺竟会日趋激烈。因此21世纪的世界是走向和平还是步入战争,关键取决于环太平洋地区各种战略力量的矛盾与合作。 相似文献

在“健康中国”战略推进和健康城市建设背景下,关注城市建成环境对公共健康影响的研究日益增加。目前相关研究主要纳入了客观测量的城市环境变量,而主观感知的城市环境变量能够体现出客观测量的城市环境变量难以捕捉的健康影响效应,具体作用有待深入探究。本研究建立了个体、社区和城市三个层面的分析框架,基于中国社会科学院社会发展战略研究院于2016年开展的“社会态度与社会发展状况”全国大样本问卷调研数据,探究主观感知的城市物质环境和服务环境对居民自评健康的影响作用并识别显著影响要素。研究发现:感知的城市环境对居民自评健康具有显著影响,其中居民对城市绿化、基础设施状况、住房保障和医疗服务的感知是影响自评健康较为主要的环境感知因素。最后本研究基于定量分析结果讨论对健康城市评价和研究的启示,推动健康城市的发展。 相似文献

ABSTRACT. It is common in empirical regional economics to use total employment as an explanatory variable while investigating issues such as the level and distribution of income and migration. This paper argues that sector-specific changes in employment and labor market performance can have different effects on economic growth, the collection of tax revenue, migration, and the level and distribution of household income. As such, it is important to model sectors separately. We find that expansions in employment opportunities for a high-wage sector such as computer manufacturing or bioengineering, a medium-wage sector manufacturing, and the lower-wage sector of retailing have differing economic consequences for a small city. We use a data intensive computable general equilibrium model to obtain these results. 相似文献

互联网技术应用对零售业空间组织影响研究进展 总被引:1,自引:0,他引:1
互联网技术应用对零售业空间组织的影响已成为当今学术界研究热点。本文利用文献资料法和对比分析法,梳理了国内外互联网技术应用对零售业空间组织结构、零售企业区位选择与布局、市场空间等方面的影响研究,并提出了未来人文地理学须进一步强化的研究内容。结果表明:20世纪90年代中期以来,互联网技术应用对零售业空间组织影响的研究成果日益丰富,且涉及到经济地理学和商业学等学科,研究方法主要以定性为主,且定量研究日益增多,但对互联网技术应用对传统零售业区位选择和销售腹地的影响、中小网络零售企业空间组织、运输距离对网络零售企业销售空间影响以及出口跨境网络零售企业销售空间格局等方面研究还需完善,未来研究应注重吸收其他学科理论和方法,强化实证研究结论的科学性。 相似文献
