“资源陷阱”成因与作用机制分析

自然资源包括矿产资源、土地资源、水资源和生物资源，这些资源对于区域经济增长均具有重要作用，是一国实现工业化和城市化的物质基础。但总体而言，在对物质财富创造的过程中。矿产资源的作用最为关键，往往是落后地区经济起飞阶段的主要依托和参与区际分工的比较优势所在。     

必须十分重视节约用电

节约用电,是指加强用电管理,采取技术上可行、经济上合理的节电措施,减少电能的直接和间接损耗,提高能源利用效率和保护环境. 能源等自然资源是人类赖以生存和发展的基础,是经济社会可持续发展的重要物质保障.我国人均能源资源占有量不足,石油、天然气和煤炭等资源的人均占有量远低于世界平均水平.能源资源供给不足已经成为我国经济社会发展的重要制约因素.同时,我国目前单位国内生产总值能源消耗又大大高于世界平均水平,许多行业和地区能源利用效率低、浪费大、污染重,靠大量消耗能源资源支撑经济增长,不仅使能源资源约束矛盾更加突出,环境压力加大,也制约了经济增长质量和效益的进一步提高.     

可持续发展视角下的土地资源用途规银——基于土地约束新古典经济增长模型的思考

从不存在土地约束的新古典经济增长模型和存在土地约束的新古典经济增长模型入手,说明了土地约束对于经济长期持续增长具有阻碍作用。在此基础上阐释了土地用途规制与土地资源可持续利用之间的内在逻辑,并从城市化对土地需求的助推、地方政府经济利益的驱动、农地产权制度的缺陷、土地征收制度的不健全和权力寻租的角度分析了目前我国土地用途规制的内在困境,并据此提出了相应的规制思路。     

资源约束下的经济增长研究

现有的经济增长理论对自然资源重视和分析不够深入,时经济增长可持续条件的研究忽视了自然资源的贡献。文章认为,探讨经济有效增长问题的出发点和立足点就在于重新认识自然资源,必须重视自然资源这一经济增长的基础变量,考虑自然资源约束。     

中国社会经济政策的主调

实现科学发展与社会和谐以及为此而进行的体制改革和制度建设,是中国当前乃至整个现代化建设时期社会经济政策的主调。中国20多年来经济发展和改革开放取得了重大进展,目前保持着良好的发展势头。与此同时,人们也越来越多地注意到,在中国经济和社会发展的潮流中,有许多令人眼花缭乱的矛盾:一是资源和环境的制约。一方面,现在经济发展的物质技术基础比过去雄厚得多,能源和原材料的生产量、交通运输能力的增长,是过去所不能想象的;另一方面,随着经济规模的扩张,能源、水、土地和其他重要资源的需求急剧增长,资源约束和环境压力比过去任何时候…     

《资源与增长》评介

我国在高速的经济增长中。资源的大规模消耗引发的资源供求矛盾越来越突出,环境问题日趋严重,对工业增长中的资源和环境约束问题自20世纪90年代开始受到重视。如何在资源环境强约束条件下实现中国工业的长期稳定快速增长,是一个亟待深入研究的重大理论和现实问题。作为国家社会科学基金重大项目的研究成果——《资源与增长》(金碚等著)一书已于2009年1月由经济管理出版社出版。该书在土地、水资源、能源、矿产资源、环境对工业增长影响进行深入分析的基础上。就资源环境对我国工业增长的总体影响进行了计量分析,对我国工业增长的性质、资源环境约     

农村土地整治的工程化及其成因

人口、环境、资源和发展已成为当今世界最关心的问题,而这些问题都离不开土地及其开发利用。从一定层面讲,土地资源能否实现可持续利用直接关系资源、环境和社会的可持续发展。土地资源的有限性、差异性、空间性和持续性也决定了其作为最宝贵的自然资源,是一切资源之首,一切安全之首。而我国农村人口基数大,增长速度快,耕地后备资源不足,人...     

中国经济增长的创新效应与能源效应驱动力研究 ——基于技术创新的视角

产能过剩、能耗过高是中国经济提质增效的核心阻碍,而技术创新是化解的关键。本文将结合耦合理论建构经济增长、创新效应及能源效应的逻辑分析框架,并引入VECM模型,分析在创新效应与能源效应单轮、双轮驱动下,经济增长的共同趋势及差异化特征。研究结果表明：（1）从单轮驱动看,创新效应与能源效应均是支撑经济增长的驱动力;（2）从双轮驱动看,创新效应与能源效应彼此作用、影响,形成“聚合”驱动力,共同推进经济增长;（3）从单轮与双轮驱动比较看,两种效应的“聚合”对经济增长的驱动效应更优。可见,中国经济的高质、高效增长需要双轮协同发力,应以技术创新为引领推进产业及能源的全面创新,以更好的发挥两者合力,实现经济可持续增长。     

曹远征:中国经济前景何在?

中国经济增长条件发生了深刻变化,出口导向型经济不可持续,低成本制造竞争优势受到挑战,投资驱动机制正在转换,能源耗费型经济难以为继,传统增长方式已失去支撑,中国经济增长环境进入了一个新阶段。     

尤化火电企业能源管理

能源是国民经济和社会发展的重要物质基础．资源不足造成的能源短缺已成为制约我国经济持续发展的重要因素。粗放型经济增长方式仍然是目前中国经济发展的根本约束;能源利用效率低、能耗高、能源严重浪费现象十分严重。能源的紧缺加上能源绝对消耗量的逐步升高,提高能源利用效率的呼声也随之越来越高,整个社会对能源管理的重视程度逐步提升。     

Divergent patterns of engagement in Internet standardization: Japan,Korea and China

This article analyzes the engagement of Japanese, Korean and Chinese participants in the development of Internet standards at IETF on the basis of four quantitative metrics: attendance, patenting, authorship and leadership. The results are strikingly divergent. Japanese involvement in Internet standardization began early and Japan was, for many years, second only to the U.S. in terms of IETF participation. Though Japanese participation has declined since the early 2000s, Japan remains a major contributor to IETF standardization. Korean involvement in IETF has always been significant, but below the levels of Japan and major European countries. Korean participation in IETF has also declined over the past decade, and has been dominated by one firm, Samsung. Though meaningful Chinese involvement in IETF did not begin until the mid-2000s, it has rapidly expanded in recent years. Today, China is a major player in numerous areas of Internet standardization in terms of three metrics (participation, patenting and leadership), and is rapidly gaining in terms of document authorship as well. Most of China׳s recent IETF involvement can be attributed to Huawei, though other Chinese firms have recently begun to increase their participation in the organization. Thus, contrary to some views that China׳s engagement with standardization is primarily one of indigenous innovation and “catching up”, China׳s experience with IETF demonstrates deliberate and effective engagement with a major Western standards-development organization on its own terms.

Whose Image is it Anyway?: Some Considerations of the Curricular Importance of Subject Image in Secondary School Design and Technology Education

This paper explores the idea that a sense of school subject image is a necessary feature of curriculum management and a potent force for change. The discussion centres on the view that all school subjects have an image and that if those intimately involved with the subject do not control the image then someone else does! In such circumstances the image is the product of past encounters and old euphemisms and is unlikely to hold the changed realities.The UK developments in Design and Technology education (the term Design and Technology is used to denote the school subject defined under this heading by the UK National Curriculum, 1995) have created something of an image problem which has interesting international parallels. Some of these problems are due to clearly discernible internal tensions and an ambiguous relationship with other subject areas.Through greater attention to subject image internal controversies might be acknowledged and resolved, relationships with other subject areas can be more meaningfully understood and practitioners can be helped to make sense of curriculum change.

Material power and normative conflict in global and local agrifood governance: The lessons of ‘Golden Rice’ in India

This special section aims to investigate the interaction of global and local forces in shaping agrifood governance. It starts from the recognition that a multitude of actors and norms shape today’s agrifood system. The resulting opaqueness of the systems makes it extremely difficult to understand and explain processes and outcomes of agrifood governance. Given the sustainability challenges facing the agrifood system, improvements in our understanding of what the interaction of global and local actors and norms means on the ground are urgently needed, however. The section, therefore, analyses agrifood governance in India across a selected group of cases. It does so by employing a systematic framework emphasizing the material and ideational dimensions of power and their interaction. The section has chosen India as the setting in which to analyze this interaction due to the crucial role the food demand and supply of this rising power plays in today’s agrifood system. This article provides the special sections’ analytical framework, which uses the interplay of material and ideational dimensions of power as a focal lens. In addition, the article applies this framework to an empirical study of the political conflict around GMO foods in India, specifically the case of ‘Golden Rice’.     

Diffusion and usage of public e-services in Europe: An assessment of country level indicators and drivers

We analyze the state of the art of indicators on e-government, e-health, e-procurement and e-participation. We survey the main methodological properties of these indicators, and highlight their heuristic potential. Further, we address empirically the issue of the explanation of the availability scores, i.e. how the supply of the various e-services in each country is affected by political, institutional and socio-economic differences, and is followed by actual usage. The econometric analysis uncovers the importance of broadband penetration and higher education as drivers for most of the types of e-services and users (citizens and businesses). Moreover, a corruption-free and agile public sector proves to be an important pre-condition for more effective supply and usage. Despite data limitations and the complexity of the underlying diffusion phenomena, our study is the first truly longitudinal contribution aimed at disentangling the common drivers of such an important phenomenon – the e-services availability and usage across European countries. As such, this work appears useful to inform the policy debate and practice, in a phase characterized by a prospective reorientation of the public e-services provision and policy agenda.
