谈体育教学改革发展趋势

体育教学“以人为本”观念形成的社会环境是现代化发展的必然结果。我们教育改革思路提出“健康第一”的指导思想，同样验证了“以人为本”的现代体育观念的社会环境背景。学生对体育课的要求和看法将对体育教学改革提供“主体”依据，体育教学改革要“以人为本”。     

Market microstructure in a global B2B network

On‐line marketplaces raise several interesting issues, among them the relevance of location when content is digitized, and the assessment of a supplier's capabilities when buyers worldwide only have electronic contact with sellers. In global B2B on‐line marketplaces, market microstructures, i.e. which firms compete for the same customers, are thus likely to be influenced by how customers value location and firm capabilities in their decisions to do business with different suppliers on‐line. We suggest that both these sets of attributes will continue to matter on‐line—firms possessing similar capabilities, as well as firms that are similar in location by country, time zones or clusters, will compete for business from the same customers. We model the similarity in competitive positions between pairs of firms based on the overlap in their customer networks, using data on actual interactions between supplier and customer banks on an electronic trading system. Using QAP network regression techniques on the 100 largest banks in this industry, we find that similarity in capabilities influences who competes with whom, and that location still matters in a global B2B exchange. Interestingly, location influences who a firm's competitors are, but not where its customers are from. Copyright © 2001 John Wiley & Sons, Ltd.

区域经济发展差距:新经济地理、要素流动与经济政策

改革开放后,中国区域经济发展差距主要表现为区域间差距的扩大,而非区域内部差距的扩大。这一现象的发生是多方面原因共同作用的结果:在新经济地理因素的影响下,具有区位优势的东部沿海地区吸引了中西部地区大量的生产要素进行跨区域流动,加上中央政府的政策导向作用,使得中国经济发展差距呈现出逐步扩大的趋势。因此,中央政府应该采取有力措施,以便在全国形成合理的区域分工,进而达到缩小区域经济发展差距的目标。

能源新论——兼论树立科学的能源观

能源在人类社会中是一个历史范畴,不同文明时期的主导能源之间有着深刻的历史联系。工业社会的主导能源本质上是化学能源,这决定了它的局限性。面对工业能源危机,人类必须开拓出比化学能源更深层次的新能源,这就是物理能源。物理能源的开发利用及其向主导能源的转化,是今日经济社会发展的必然趋势。     

体育教学中如何进行美育教育

从体育发展状况看,许多发达国家都十分重视学校体育中的美育教育.我国学校体育教育除了要让学生掌握体育的基本知识、基本技术、基本技能外,还需要把美的蕴意有目的地注入体育教学中去,以便培养和提高学生的审美意识以及审美观,培养和发展学生对体育美的鉴赏能力和创造能力,最终达到身体美、心灵美、行为美.

Structural Decomposition Analysis of Physical Flows in the Economy

Many environmental problems can be attributedto the extraction and emissions of physicalsubstances. Increasing our understanding of theeconomic and technological driving forcesbehind these physical flows can contribute tosolving the environmental problems related tothem. The input-output framework is a usefulsetting in which to integrate detailedinformation about economic structure andphysical flows. In this article a specificmethod in input-output analysis is reviewed,namely Structural Decomposition Analysis (SDA).It is based on comparative static analysis,which decomposes historical changes of a policyvariable into determinant effects. SDA has beenapplied, for example, to analyze the demand andtechnological driving forces of energy use,CO₂-emissions and various other pollutantsand resources. This article examines thetheoretical aspects of structuraldecomposition, in particular those concerningphysical flows and environmental issues.Furthermore, the article includes an extensivesurvey of empirical studies.     

Transport development and the evolution of economic geography

In this paper, based on the recent advances in the new economic geography (e.g., Fujita et al. [12]), we analyze impacts of transport costs on the spatial patterns of economic agglomeration. We first identify prototypes from the existing models, and explain the mechanism of how transport costs influence the balance between economic forces of agglomeration and dispersion. We then investigate the transformation of the agglomeration/dispersion patterns given gradually decreasing transport costs for different goods.Received: Received: July 2004 / Accepted: January 2005, Accepted: Received: July 2004 / Accepted: January 2005, JEL Classification: R12Tomoya Mori: Correspondence toThe authors are grateful to David Bernstein, Tatsuo Hatta, Komei Sasaki, Tony E.
