新时期珠江三角洲城市群发展战略的思考   总被引：5，自引：3，他引：2  

周春山  金万富  史晨怡 《地理科学进展》2015,34(3)

近年来,国内外经济形势发生显著变化,以传统制造业为主的珠三角城市群面临新的挑战,珠三角下一步如何发展成为必须解决的新问题。现状,将其与国内外城市群对比,提出了珠三角发展战略思路。研究结果表明:2000-2013年期间,珠三角城市群经济发展速度有所降低,区域经济发展差距逐渐缩小;人口红利面临枯竭;产业结构向高级化转变,经济全球化程度下降等;珠三角城市群发展水平和竞争力与国外世界级城市群相比差距较大;与国内长三角、京津冀城市群相比,总体发展势头下降。在此背景下,应将产业技术创新、土地节约集约利用、人口政策创新、区域合作与人文引领作为新时期珠三角城市群发展战略的主要方向。  相似文献   

How to increase technology transfers to developing countries: a synthesis of the evidence     

Ana Pueyo  María Mendiluce  María Sanchez Naranjo  Julio Lumbreras 《Climate Policy》2013,13(3):320-340

The existing United Nations Framework Convention on Climate Change (UNFCCC) has failed to deliver the rate of low-carbon technology transfer (TT) required to curb GHG emissions in developing countries. This failure has exposed the limitations of universalism and renewed interest in bilateral approaches to TT. Gaps are identified in the UNFCCC approach to climate change TT: missing links between international institutions and the national enabling environments that encourage private investment; a non-differentiated approach for (developing) country and technology characteristics; and a lack of clear measurements of the volume and effectiveness of TTs. Evidence from econometric literature and business experience on climate change TT is reviewed, so as to address the identified pitfalls of the UNFCCC process. Strengths and weaknesses of different methodological approaches are highlighted. International policy recommendations are offered aimed at improving the level of emission reductions achieved through TT.  相似文献   

中国淡水和近海鱼类的生态对策研究     

陈刚 《广东海洋大学学报》1996,(2)

通过渐近体长（Ｌ∞），渐近体重（Ｗ∞）、生长系数（Ｋ）、初次性成熟年龄（Ｔｍ）、最大年龄（Ｔｍａｘ）、瞬时自然死亡率（Ｍ）和种群繁殖力（ＰＦ）等七个生态学参数的比较，研究１９种淡水鱼类和１５种近海鱼类的生态对策。根据ｒ—选择和ｋ—选择的典型特征以及各参数间相互关系的显著性，３种鲟鱼类属ｋ—选择；牙鲆等５种近海鱼类偏向ｋ—选择；青鱼、勒氏笛鲷等９种鱼类偏向ｒ—选择；鲤、黄鲫等１７种鱼类为ｒ—选择。对ｒ－ｋ选择的资源特征及其对捕捞的反应做了分析，只有合理控制捕捞强度和起捕年龄，才能保护资源，获得较好的经济效益。  相似文献

Research on regional comprehensive development in developed regions —The case of Shanghai-Nanjing-Hangzhou area     

Xinxian Lu 《中国地理科学(英文版)》1992,2(3):256-265

The developed regions are faced with the problems of regional comprehensive development, and the research on regional comprehensive development has become a trend in the world. To optimize regional industrial structure and to select and determine scientifically the spatial development strategy of regional industries are the central themes to be solved for the research on regional comprehensive development in the developed regions. This paper proposed the basis for optimizing regional industrial structure, and the main factors of selecting and determining the regional leading industries. Based on this, the paper puts forward the leading industries and the spatial development strategy in Shanghai-Nanjing-Hangzhou area in the future ten or more years. Combined with the situation of Shanghai-Nanjing-Hangzhou area, the paper also discusses some problems of locating superior developing axis to benefit the rational distribution of regional productive forces.  相似文献   

RESEARCH ON THE COASTAL DEVELOPMENT STRATEGY IN CHINA: TAKE SHANDONG PROVINCE AS AN EXAMPLE     

李兴弟 《中国地理科学(英文版)》1992,2(1):80-86

Nowadays in China, the coastal development strategy (CDS) aims to make the region (with population 160 million) ahead of developing export-oriented economy and to promote the inland economic prosperity at the same time.The paper analyzes the CDS based on the background of coastal area and the situation at home and abroad, and mainly discusses the relevant tactics in Shandong Province, China.  相似文献

Development and the Household: Missing the point?     

Edward?R.?CarrEmail author 《GeoJournal》2005,62(1-2):71-83

Over the past two decades development has been shifting its focus toward smaller scales and particular problems. As a result, the household has become an increasingly important institution for development, and has come under increased scrunity as development practitioners and scholars seek to better understand this institution’s functions and foundations, trying to ‘get the household right’. These efforts, rather than clarifying the character and the function of the household, have contributed to its indeterminacy by reifying the very institution they seek to analyse. Arguing that these efforts fundamentally miss the point of examining the household, this paper introduces a different framework of analysis that addresses the household not as a fixed object of research, but as a local construction that embodies flows of power and knowledge both within and transcending the local. Using the example of varying constructions of the household in two villages in Ghana’s Central Region, this article illustrates how such an approach allows us to address the various functions of the household as particular embodiments of these flows, an approach that better explains the endurance or ephemerality of these functions. Such an approach provides a stronger foundation for the consideration of how particular constructions of this institution may have troubling implications for issues like gender equity and sustainability.  相似文献
