中国城镇化地区贡献的内陆化演变与解释——基于1982-2008年省区数据的分析

改革开放30 年来,中国持续快速的经济发展和城镇化受到了世界关注.由于政策环境和地理基础的差异性,地带间差异成为中国城镇化空间差异的主要特征:在多元动力的共同推动下,东部十省的快速城镇化为全国的城镇化进程贡献了49%.新世纪以来,随着西部大开发、东北老工业基地振兴和中部崛起三大区域发展战略的相继提出,政策和地理基础的地带间差异逐步缩小,国内外投资重点向内陆转移,外出务工人员的回流与创业成为人口流动的新特征,带动中西部地区对全国城镇化的贡献迅速提升,中国城镇化的重心向内陆转移,省区城镇化趋同现象比较明显.这些新现象在2005 年以来更加强化.实证结果表明,区域发展战略的提出促进内陆省份对全国城镇化的贡献率提高了8.7%,但并没有对中国省区城镇化的动力机制产生影响;沿海地区产业转移和国际市场的开拓将成为内陆地区城镇化的重要依托.     

A Twilight Zone: Identity Crisis in French Geopolitics

The paper initially describes some of the most important historical processes that have conditioned France's geopolitical position in the contemporary world. It discusses the current changes in France's geopolitics as a changing reality of international relations and as a changing discourse of scholars and experts, that reflects those real world changes. The paper focuses on French politics in Africa and on France's policy in Europe after the end of the Cold War. In Africa the French post-colonial empire with its close ties between domestic regimes, French business interests and the French state becomes unsustainable after the bipolar rivalry has been suspended. In Europe French policy can no longer be presented as either an independent view among a series of others (Europe des patries) nor as a successful effort to press French views by way of a larger European entity. The paper presents an overview of geopolitical literature written in France as a reflection of these conditions.     

多水平/尺度的驱动力变化与沙漠化之间的关系——以内蒙古乌审旗为例

沙漠化是土地退化形式之一,它是自然因素和人类活动相互作用的结果。本文以内蒙古乌审旗为研究区,在多种空间数据基础上,基于等级理论,使用多水平统计模型构建了从局地到区域的模型,揭示不同尺度的影响因素与该地区沙漠化的关系。对遥感影像的分析表明该地区1977—2007年沙漠化扩展的趋势减缓并逆转;多水平统计模型分析表明,多尺度的驱动因素可以解释该地区近30年的沙漠化变化,特别是政策因素对该地区沙漠化逆转影响较大。本研究可为乌审旗及类似地区沙漠化变化机理研究提供参考。     

Back to the Future? Planning for environmental outcomes and the new Caring for our Country program

The Australian government Caring for our Country (CfoC) program, first announced in 2008, has sought to build on and enhance previous experience with Australian natural resource management policy. This paper critically examines the initial design, planned delivery, and first round of competitive funding outcomes of the new program. This analysis shows that the initial design and delivery of the CfoC model was ad hoc, politicised, and lacking in transparency. The paper concludes that a more systematic and transparent approach for achieving sustainable environmental outcomes is required in order for this new program to achieve its intended objectives. These implications are of interest to Australian and international geographers, natural resource planners, scientists and policy makers concerned with the design, delivery and outcomes of large natural resource and environmental management programs.     

Disaster Declarations and Major Hazard Occurrences in the United States∗

This article examines the potential geographic inequities between major hazard events and U.S. presidential disaster declarations at the county level from 1965 through 2004. The previous literature suggests that the disaster declaration process is highly politicized and not necessarily based on need. We hypothesize that there is a spatial inequity between the receipt of disaster declarations and the distribution of major hazard events. The results indicate that the geographic distribution of disaster declarations is not totally explained by the spatial pattern of major hazard events. In some locales, state experience in submitting disaster requests and achieving success translates into more disaster declarations (holding everything else constant), providing further evidence of the political nature of the process.     

Older People and Transitions from Employment to Nonemployment: International Perspectives and Policy Issues

The Organization for Economic Co-operation and Development (OECD) has identified population aging as one of the most important challenges facing OECD countries and has highlighted the need for people to work longer and for job prospects for older workers to be enhanced. This article provides a summary review of a recent OECD report, Ageing and Employment Policies—Live Longer, Work Longer, as a platform to highlight differences between countries in demographic profiles and projections and in patterns of formal labor market participation among older workers. Drawing on selected information from a broader evidence base, it unveils important differences between countries in the scale of demographic and associated labor market challenges. It also explores factors affecting labor market transitions among older workers and age-related and other barriers to paid work among older people, emphasizing the diversity of experience between individuals. Finally, it highlights some strategic challenges for policy.     

How good is good? Human values and Europe's proposed Marine Strategy Directive

The adoption of the proposed European Marine Strategy Directive is an opportunity for a comprehensive policy for protecting, improving and sustainably using Europe's environmentally degraded seas. It calls for an ecosystem-based approach to management where humans are regarded as a key system component. Although the proposed wording has been the subject of fierce debate, the central policy goal remains achieving "Good Environmental Status". The interpretation of "good" is key to implementation and relates to human values and worldviews. We demonstrate how these vary widely across Europe. Solution of fundamental considerations such as the assignation of reference states, the balance between precautionary and evidence-based action, the degree of subsidiarity, and conservation strategies including marine protected areas, will ultimately depend upon public understanding, involvement in and support for the Directive. The social element, critical to effective adaptive management, requires greater attention within the context of a regional seas geographical framework.     

中西部地区承接产业转移的影响因素研究

将中西部地区划分为东北、中部、西北、西南4个区域,采用1995—2013年的相关数据,分析各区域在承接东部发达地区产业转移过程中的主要影响因素。选取的影响因素包括资本存量、经济规模、劳动力成本、人力资源和路径效应。结果发现:4个区域的路径效应、资本存量与产业转移承接地均存在显著正相关关系;人力资源与产业转移承接地存在正相关关系,但东北、西北地区不显著;劳动力成本与产业转移承接地存在负相关关系,但对东北地区不显著;除中部地区外,经济规模与产业转移承接地并不存在显著相关关系。中西部区域地方政府和企业家在促进产业转移进程中应充分发挥比较优势,根据不同影响要素制定宏观政策与微观引资策略。     

Air Quality,Climate, and Policy: A Case Study of Ozone Pollution in Tucson,Arizona

This article addresses the need to better understand the complex interactions between climate, human activities, vegetation responses, and surface ozone so that more informed air-quality policy recommendations can be made. The impacts of intraseasonal climate variations on ozone levels in Tucson, Arizona from April through September of 1995 to 1998 are determined by relating variations in ozone levels to variations in atmospheric conditions and emissions of ozone's precursor chemicals, volatile organic compounds (VOCs) and nitrogen oxides (NO_x), and by determining month-specific atmospheric conditions that are conducive to elevated ozone levels. Results show that the transport of ozone and its precursor chemicals within the Tucson area causes the highest ozone levels to be measured at a downwind monitor. The highest ozone levels occur in August, due in part to the presence of the North American monsoon. Atmospheric conditions conducive to elevated ozone concentrations differ substantially between the arid foresummer (May and June) and the core monsoon months ( July and August). Transport of pollution from Phoenix may have a substantial impact on elevated ozone concentrations during April, May, and June, while El Paso/Ciudad Juarez –derived pollution may contribute significantly to elevated ozone concentrations in August and September. Two broad policy implications derive from this work. Regional pollutant transport, both within the U.S. and between the U.S. and Mexico, is a potential issue that needs to be examined more intensively in future studies. In addition, spatiotemporal variations in sensitivities of ozone production require the adoption of both NO_x and VOC control measures to reduce ozone levels in the Tucson area.
