辽宁沿海经济带工业环境效率分析

环境效率是生态效率的重要组成部分。基于环境效率对于指导区域经济与环境协调发展的重要意义,以重工业基地辽宁沿海经济带为例作环境效率研究,应用数据包络分析(DEA)和随机前沿分析(SFA)测算辽宁沿海经济带2001~2009年工业环境效率和产出弹性。在此基础上利用Tobit模型构建多元线性回归,分析工业环境效率的关键影响因素。结果表明:2001~2009年辽宁沿海经济带工业环境效率有大幅提高,但与理想状况仍有一定差距。其中大连的工业经济增长主要依靠劳动力推动,对环境成本的依赖正在减小,丹东、营口和葫芦岛3市的工业增长需要牺牲更多的环境成本。重工业化、资本密集化和高新技术化不利于工业环境效率提高,经济发展水平的提高则极大地促进了工业环境效率的提高。所有制结构、生产规模、外商投资和环境管理力度等因素因其作用的两面性,对工业环境效率无有效影响。     

Reach Out and Touch Someone: AT&T's Global Operations in the 1990s

The late twentieth century has witnessed the rapid expansion of a global telecommunications infrastructure and flows of information. Few case studies of individual corporations in this industry exist. Following the breakup of its U.S. monopoly in 1984, AT&T, the world's largest telecommunications provider, steadily expanded its international operations. This paper examines the institutional and spatial dynamics that underpin AT&T's global strategies, including transoceanic fiber cables, employment, manufacturing facilities, joint ventures, and operations in every major market area around the world. It ascertains these efforts in light of the emergence of post-Fordist regime theory and argues that corporate-specific case studies continue to remain an important part of economic geography.     

用NCEP／NCAR再分析辐射资料估算月平均地表反照率

本文利用１９７９年￣１９９５年１７年平均的ＮＣＥＰ／ＮＣＡＲ（Ｎａｔｉｏｎａｌ Ｃｅｎｔｅｒ ｆｏｒ Ｅｎｖｉｒｏｎｍｅｎ－ｔａｌ Ｐｒｅｄｉｃｔｉｏｎ／Ｎａｔｉｏｎａｌ Ｃｅｎｔｅｒ ｆｏｒ Ａｔｍｏｓｐｈｅｒｉｃ Ｒｅｓｅａｒｃｈ,美国国家环境预报中心／美国国家大气研究中心）再分析辐射资料估算了全球月平均地表反照率．从所得结果的时空分布来看,用ＮＣＥＰ／ＮＣＡＲ辐射资料得到的全球地表反照率基本     

论冷战后国际政治的基本态势及世界政治地理的研究任务与重点

本文立足于政冶地理学的基本理论，从冷战后国际政治基本态势的分析入手，系统阐述了当前世界政治地理研究的基本任务，并在此基础上提出了当前及今后一段时期世界政治地理研究应以世界政治地理格局的演变、国家形成与消亡的地理政治背景、国际领土及边界争端和各国行政区划的基本原则为重点。

中国区域经济差异变化的空间特征及其政策含义研究

采用了种省区人均国内生产总值与全国平均值的离差和比离两个指标，分别判断１９９０￣１９９５年我国区域经济绝对差异和相对差异变化的空间状态，并进一步阐明了其调控区域经济差异的政策含义。     

The knowledge–space dynamic in the UK bioeconomy

The loss of manufacturing employment to lower cost economies has meant that countries like the UK have sought to promote innovation in areas such as biotechnology. The emergence of the 'bioeconomy', however, has been highly uneven, with concentrations of activity in certain countries and particular regions in those countries. In the UK, for example, there are four major concentrations of the bioeconomy. Each of these concentrations exhibit distinct patterns of knowledge and spatial inputs into the innovation process, meaning that it is important to consider the knowledge–space dynamic in and of each region.

平遥古城民居之门的形态变迁及其家的观念表征

新旧文化地理学者对物质空间与文化观念的关系有着不同的理解,是引发人文地理学文化转向的主要动力,而“文化超机体”的概念正是其争论的焦点。民居及其空间构成记载着城市历史,传递着城市记忆,是形成中国城镇历史特征的文化空间主体。通过解读平遥古城民居大门的文化属性,探究其文化过程发现：一方面,“家”作为文化超机体概念借由大门这一特定空间符号不同程度地留存于民居当中;另一方面,不同民居大门本身的文化特征,通过空间过程的追溯得以呈现。将文化的空间分析与空间的文化研究融入到微观形态分析的范式中,是对文化地理学超机体概念的批判性继承做出的呼应。     

产业结构高度化对城市生产性空间的影响研究

以产业结构升级的主要途径--产业结构高度化为切入点,在分析产业结构高度化实现的两种方式,即产业结构横向高级化和产业结构纵向高级化的基础上,仅以空间经济为视角,运用阿隆索(W.Alonso)的竞标地租理论,分析了产业结构横向高级化、产业结构纵向高级化分别对城市工业和服务提供空间的影响,指出了城市生产性空间布局的演变有其内在规律性,以及违背产业发展规律而强行重组城市空间的危害性.只有根据产业结构高度化的实现方式并结合产业类型,有针对性地提供发展空间才有助于社会经济发展.
