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. 相似文献

《欧洲风景公约》是第一个将风景作为规范对象的国际公约,这标志着“风景”概念从科学知识转化为行为规范,并成为跨国治理的政策工具。欧洲风景公约作为“软法”的本质特征是其规定性与确定性,精确的概念和严密的逻辑是公约文件的基石。从法规文本解读的角度全面阐释了公约的风景定义及其重要意义;深入解析了公约的总体措施与行动框架,评述了风景知识与风景行动的相互关系;并对公约在国家层面实施的干预机制、具体的实施方法进行了详细的阐述与解释。 相似文献

生态空间承载着人类、动植物和自然生态多种过程,是生态系统服务功能的策源地和枢纽区。以实施生态空间管控为导引,借助多源数据和ArcGIS、C-Plan系统工具,核心应用系统保护规划(SCP)技术,建立生态服务测度下市域生态空间管控体系的构建方法。基于此,以哈尔滨为例,以不可替代性为表征实现生态空间测度指标综合与功效评价,构建生态空间关键区识别、功能区优划以及网络格局优化模型,提出“重点保护-分区指引-格局优化”的市域生态空间管控体系,为新型城镇化及绿色发展战略的实施奠定科学基础和提供技术支撑。 相似文献

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year. 相似文献

杭嘉湖平原地区土地利用变化驱动机制分析 总被引:6,自引:0,他引:6
选择位于杭嘉湖平原地区社会经济快速发展的浙江省海盐县为研究区,利用遥感数据,对研究区土地利用类型的空间转移与格局变化进行分析的基础上,选取研究区土地利用变化的社会经济驱动因子,运用典型相关分析方法诊断各社会经济驱动因子对土地利用变化格局形成贡献作用的大小,同时运用典型相关系数和冗余度分析,检验了分析结果。研究结果表明,人口密度、单位面积工业总产值、单位面积农业总产值、城镇化水平、农民人均年纯收入等5个因子是影响研究区土地利用变化的主要社会经济驱动因子。 相似文献

从时空间行为视角切入,采用居民活动日志搜集成都市新、旧城区的绿地使用者时空路径数据集,辨识不同时间预算人群的潜在可用绿地分布及人群特征,并通过构建绿地时空享用量模型,从时空制约角度对成都市新、旧城区的绿地享用公平性展开分析。研究结果显示:1)成都市新、旧城区的绿地享用格局在辐射范围、享用强度和人群绿地享用时间预算方面具有时空间分异特征;2)日常出行链中固定性活动占比会对人群绿地享用时间预算产生影响;3)随个体时间预算不断被固定性活动所挤占,长距离通勤加班族、担负接送小孩上学的上班族等时间短缺型群体的绿地享用机会被深度制约,日益成为潜在的绿地享用弱势群体,在时间短缺型群体的潜在活动路径范围内增加绿地供给,有利于提高此类人群享用绿地的机会,从而提高片区的整体绿地享用公平性。 相似文献

The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies,
and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing
that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn
“productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path.
Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by
the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as
long term and endogenous outcomes. 相似文献

In little more than a century life expectancy has doubled in most parts of the world. Neither facts nor theory support the view that this Mortality Revolution is due to the Industrial Revolution and the era of rapid economic growth that ensued. Rather, both revolutions mark the onset of accelerated and sustained technological change in their respective areas. They occur largely independently of each other, the later occurrence of the Mortality Revolution being due to the later development of biomedical vis-a-vis physical knowledge. Comparative study of the two should prove fruitful. Although entrepreneurship is important in each, there appear to be differences in the underlying motivations and the role of private property and other institutions. Links between technological change, on the one hand, and scale of operation, capital inputs, and education, on the other, also offer promising possibilities for comparative study.The author is grateful to Donna Hokoda Ebata and Christine M. Schaeffer for excellent assistance, the University of Southern California for financial support, and to Eileen M. Crimmins, Samuel H. Preston, Morton O. Schapiro, Roger S. Schofield, and two referees for helpful comments. 相似文献

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and
policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological
economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy
and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist
ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition
to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning,
development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship,
equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.
