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

雇佣关系是企业所有者和劳动者以市场为导向的经济合约模式,与社会制度没有必然联系。面对组织变革,传统的长期雇佣在降低成本、技术进步、战略调整等因素作用下逐步解体。对传统雇佣关系的否定并意味着对长期雇佣的否定,构建好新型雇佣关系对企业和员工都是必要的。 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

二元经济是发展中国家在发展过程中最基本的经济特征.从信息和知识的角度看,任何经济系统、组织、个人都是信息和知识生产、收集、传递及利用的装置,二元经济形成的关键在于不同区域在信息和知识的生产、收集、传递及利用能力及效率上的差异.因此,二元经济如何发展和转换完全取决于该区域内与信息和知识利用相关能力的形成和发展. 相似文献

利用第三、四和五次全国人口普查资料,对长江三角洲、珠江三角洲和京津唐地区人口增长和空间分布的变化过程进行分析.研究表明,自1980年代以来,各城市密集区人口增长速度加快,人口规模不断扩大;空间分布变化幅度大,总的趋势是集中化、不均衡化;人口变动状况具有阶段性差异;外来人口的迁移流入是人口变动的主导因素.在此基础上,探讨了城市密集区发展过程中的人口演化趋势以及人口变动规律,其结论是:城市密集区人口变动遵循逻辑斯蒂增长规律、波动推进规律、圈层扩散与等级扩散规律,人口增长将由高速到低速,人口分布将由集中化迈向相对地均衡化. 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

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.

Productivity Growth, Efficiency and Outsourcing in Manufacturing and Service Industries 总被引:8,自引:1,他引:8
Almas Heshmati 《Journal of economic surveys》2003,17(1):79-112
This paper is a survey of recent contributions to, and developments of, the relationship between outsourcing, efficiency and productivity growth in manufacturing and services. The objective is to provide a thorough and up–to–date survey that provides a significant discussion on data, as well as on the core methods of measuring efficiency and productivity. First, the readers are introduced to the measurement of partial and total factor productivity growth. Different parametric and non–parametric approaches to the productivity measurement in the context of static, dynamic and firm–specific modelling are discussed. Second, we survey the econometric approach to efficiency analysis. The issues of modelling, distributional assumptions and estimation methods are discussed assuming that cross–sectional or panel data are available. Third, the relationship between outsourcing and productivity growth in manufacturing and services is discussed. The correspondence between a number of hypotheses and empirical findings are examined. Examples of varieties of relevant empirical applications, their findings and implications are presented. Fourth, measurement of inputs and outputs in manufacturing and services are discussed. Finally, to promote useful research, a number of factors important to the analysis of outsourcing, efficiency and productivity growth in the service sector are summarised. 相似文献
