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.

区位决策视角下的集群生命周期分析 总被引:1,自引:0,他引:1
本文在对当前产业集群生命周期研究述评的基础上,将集群周期划分为成长、成熟、衰退、再发展四个阶段,并从企业区位决策的视角对集群生命周期的不同阶段进行分析。然后通过考察企业区位决策因子的动态变化和集群区核心产业的区外出口量增长率、主导产业的企业数量、修正后的空间基尼系数来对生命周期阶段进行划分,分析不同阶段下政府的决策行为。 相似文献

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal
portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of
investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual
employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement
savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic
model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses
and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas
for further research identified.

Economists are increasingly interested in forecasting future costs and benefits of policies for dealing with materials/energy fluxes, polluting emissions and environmental impacts on various scales, from sectoral to global. Computable general equilibrium (CGE) models are currently popular because they project demand and industrial structure into the future, along an equilibrium path. But they are applicable only to the extent that structural changes occur in or near equilibrium, independent of radical technological (or social) change. The alternative tool for analyzing economic implications of scenario assumptions is to use Leontief-type Input-Output (I-O) models. I-O models are unable to endogenize structural shifts (changing I-O coefficients). However, this can be a virtue when considering radical rather than incremental shifts. Postulated I-O tables can be used independently to check the internal consistency of scenarios. Or I-O models can be used to generate scenarios by linking them to econometric macro-drivers (which can, in principle, be CGE models). Explicit process analysis can be integrated, in principle, with I-O models. This hybrid scheme provides a natural means of satisfying physical constraints, especially the first and second laws of thermodynamics. This is important, to avoid constructing scenarios based on physically impossible processes. Process analysis is really the only available tool for constructing physically plausible alternative future I-O tables, and generating materials/energy and waste emissions coefficients. Explicit process analysis also helps avoid several problems characteristic of pure CGE or I-O models, viz. (1) aggregation errors (2) inability to handle arbitrary combinations of co-product and co-input relationships and (3) inability to reflect certain non-linearities such as internal feedback loops. 相似文献
