我国开放式基金业绩评价指标体系的构建 总被引:1,自引:0,他引:1
投资基金业的规范与发展要求建立一个健康的运行环境 ,同时也迫切地呼唤构建一个科学的评价指标体系 ,公平、合理地考核基金经理的经营管理能力。我国的投资基金才刚起步 ,目前对投资基金业绩评价的研究尚处于萌芽状态。如何借鉴国外成熟的评价方法和指标 ,结合我国证券市场的现实给出科学、合理的评价方法和指标体系是一件十分有意义的工作。一、开放式基金的收益评估由于开放式基金随时都要接受投资者的赎回 ,投资者买卖基金单位的价格基本上就等于基金最近公布的资产净值 ,因此用净值增长率来反映基金的投资收益对于开放式基金来说是比较… 相似文献

上海证券市场投资基金绩效评估实证研究 总被引:1,自引:0,他引:1
一、引言 无论是从中国股市的发展政策,还是海外成熟股市投资者结构来看,机构化是股市投资的不可逆转之势,而投资基金将成为这场机构化进程的主力“前锋”。参与基金投资的群体越来越大,市场亟需规范科学的基金绩效评价方法和体系,一方面为普通投资者在选择投资对象时提供参考,另一方面也为基金管理公司评价本公司的基金业绩提供依据。本文利用Jensen指数评估模型和Treynor-Mazuy模型,对沪市的10只投资基金绩效进行评估。实际上,要全面衡量一个基金的整体业绩是非常复杂的,基金业绩的好坏当然与整个证券市场的行情密不可分,因此,为客观公正地评估基金之间的业绩差异,剔除系统风险的影响是非常必要的。基金的投资对象及组合是影响基金业绩的关键因素,因此评价不同基金的绩效水平应以此作为分析对象。另外,导致基金业绩评估复杂的原因还在于不同的投资风格所带来的不同管理费用,从而使基金价格和它的净值通常是不一致的。因此,为更综合全面地评估各基金业绩,本文利用基金净 相似文献

This paper discusses the problematic relationship between technology education, consumption and environmental sustainability.
The emerging global sustainability crisis demands an educational response that moves beyond mere ‘tinkering’ with classroom
practices, toward technology education which embraces life cycle thinking and ‘eco-innovation’. It will argue that the urgent
transformation to technology education for sustainability citizenship must begin with a critical examination of existing practices and assumptions which underpin unsustainability.
The initial context for this discussion will be technological education in Canada and the United States, in particular a recent
national report on the assessment of technological literacy. The paper concludes by suggesting several ‘new paths’ forward
to move technology education toward more sustainable practices and more relevance for young people. 相似文献

At the center of Schumpeter's theory of competitive behavior is the assertion that competitive advantage will become increasingly more difficult to sustain in a wide range of industries. More recently, this assertion has resurfaced in the notion of hypercompetition. This research examines two large longitudinal samples of firms to discover which industries, if any, exhibit performance that is consonant with Schumpeterian theory and the assertions of hypercompetition. We find support for the argument that over time competitive advantage has become significantly harder to sustain and, further, that the phenomenon is limited neither to high‐technology industries nor to manufacturing industries but is seen across a broad range of industries. We also find evidence that sustained competitive advantage is increasingly a matter not of a single advantage maintained over time but more a matter of concatenating over time a sequence of advantages.

This paper identifies the importance of both creativity and environmental sustainability for developing individual learners
and society as a whole. It suggests that sometimes these two concepts appear to be in tension and that, politically, each
is often championed by different communities. The relationship between creativity and environmental sustainability is explored
in three separate contexts: in a design and technology schools context where teenage learners are being facilitated to develop
creative responses within design briefs that include environmental considerations; through interviewing student teachers who
have undertaken an ecodesign project; and through interviews with professional ecodesign practitioners. The tensions, compromises
and contradictions evident where there is limited experience of environmental issues is contrasted with the level of optimisation
and creativity engaged when designers have more maturity in this area. Finally, some suggestions are made for taking forward
creativity and environmental sustainability in technology education through an ecodesign capability approach.

We examined how managers' perceptions of different types of stakeholder influences in the Canadian forestry industry affect the types of sustainability practices that their firms adopt. Both influences involving withholding of resources by social and ecological stakeholders and those involving directed usage of resources from economic stakeholders were found to drive such practices. We found that the industry and its stakeholders have moved beyond a focus on early stages of sustainability performance such as pollution control and eco‐efficiency. However, more advanced practices, such as those involving the redefinition of business and industrial ecosystems where firms locate in a region so that they can exchange and utilize wastes generated by other firms, are in their infancy. Stakeholders and firms in the industry are focused on the intermediate sustainability phases involving recirculation of materials and redesign of processes including sustainable harvesting of lumber.

We examine the effect of a firm's relations with its nonfinancial stakeholders, including its employees, suppliers, customers, and communities, on the persistence of both superior and inferior financial performance. In particular, integrating and extending the resource‐based view of the firm and stakeholder management literatures, we develop the arguments that good stakeholder relations not only enable a firm with superior financial performance to sustain its competitive advantage for a longer period of time, but more importantly, also help poorly performing firms to recover from disadvantageous positions more quickly. The arguments are supported by the analysis of a series of first‐order autoregressive models. Our findings further suggest that the positive effect of good stakeholder relations on the persistence of superior performance is not as strong as that of some other firm resources, such as technological knowledge, but it is the only factor examined that promises to help a firm recover from inferior performance. Therefore, the role of positive stakeholder relations in helping poorly performing firms recover is found to be more critical than its role in helping superior firms sustain their performance advantage.

This paper shows how idiosyncratic resources can drive sustained profitability and persistent heterogeneity under competitive conditions. Generic inputs purchased in the market become idiosyncratic resources as the result of firms' investments in customization. Analytically, we show how heterogeneous firms coexist in equilibrium as a function of customization costs. Computationally, we show that sustainable profits can emerge without ‘monopolistic’ imperfections. We consider how capability heterogeneity, resource customization cost, and ease of expansion interact to drive short-run and sustainable profits. Our results illustrate that sustainable profits may represent a small part of the total wealth created over time by a firm or industry, and that changes in factors shaping a sector's evolutionary trajectory may be more important than changes in factors that determine profits' ultimate sustainability.

In recent years, both researchers and practitioners have devoted attention to environmental sustainability issues in the fashion industry, but, despite the topic's relevance, a structured analysis of the problem is missing.This paper presents the results of exploratory case-based research aimed at identifying three factors: the drivers that push companies to adopt “green” practices, the different practices that can be used to improve environmental sustainability, and the environmental KPIs measured by fashion companies. Results include a comparison of two approaches pursued by established international companies with green-positioned brands with the efforts of small firms that have adopted alternative supply chain models. 相似文献
