风险投资的中止决策研究综述

目前国际国内对风险投资中止决策研究很少,已有的文献对风险投资的中止行为进行了探讨,发现这是影响风险投资收益的非常重要的因素,通常对于可以成功的项目而言,众多的风险投资公司的投资决策并无很大的差异,而对那些已经投资的但不能成功的项目而言,中止投资能力是影响公司长期绩效的一个重要指标.通常是那些对不良项目能及时果断采取中止投资行为的公司从长期来说,能显示出更高的投资收益.     

新形势下企业投资风险与防范以房地产企业为例

风险管理的意义不仅在于风险预测,而且在于通过科学的分析,合理的鉴别,拟订预防风险的措施。有效地控制风险不仅会降低风险发生的可能性、减少不必要的损失,还可以科学合理的应对已经发生的风险事件,进而降低风险损失。研究钢材消费的重要领域房地产企业投资风险与防范,分析房地产公司投资风险的分类和指标,选取F地产为研究对象,对实际调查中搜集到的相关数据进行处理,并在此基础上分析房地产投资风险的现状,而后分别制定了权衡投资收益与风险,优化负债结构提高资金周转率,坚持多元化投资战略,合理确定负债率和融资结构的应对措施,确保企业投资利益得到保障。     

利用产业投资基金促动房地产抵押证券化

一、我国产业投资基金的发展 产业投资基金是一种以直接投资产业为主,汇集不特定多数且具有共同投资目标的投资者的资金,委托专门的投资机构进行投资,借以分散风险并享有投资收益的一种基金。我国的基金业起步于1991年,经过十几年来的发展,绝大部分的投资基金是证券投资基金,真正属于产业投资基金的很少。到1994年4月,《产业投资基金管理暂行办法》形成送审稿并报国务院法制局审理,我国产业投资基金的发展才有所突破。

不同资本结构与所有权安排下的投资效率测度——来自我国A股市场的经验证据

本文研究了中国上市公司不同资本结构和所有权安排对投资收益和投资效率的影响,并就我国企业过度投资现象进行了测算和说明。实证结果发现,上市公司财务杠杆水平显著影响着公司投资效率和投资收益,但在影响方式上却因所有权安排的差异而有所不同。财务杠杆水平的提高对地方国有企业和非国有企业的投资收益影响不大,但显著降低了这两类企业的投资效率;中央国有企业财务杠杆水平的提高能够显著降低投资收益,但对投资效率的影响并不敏感。研究还发现,低杠杆水平的非国有企业和地方国有企业几乎不存在过度投资情况,高杠杆组该类企业过度投资却很严重;而对于中央国有企业来说,无论财务杠杆水平如何,投资效率均十分低下,过度投资普遍存在。     

增值税转型对风电建设经济评价影响及评价方法研究

增值税转型改革对我国风电项目的发展影响深远。增值税转型改革后．由于增值税抵扣,风电项目总成本费用减少,在项目投运初期,以增值税为计费基数的城市维护建设税和教育附加费也相应降低,改善了项目的财务状况。同时,论文对增值税转型前后的风电项目评价方法进行了研究,结论表明：在增值税转型后,项目的盈利能力和抗风险能力有较大提升。论文提出了风电项目经济评价中针对财务指标的两种计算方法,并进行了对比分析,指出以不含增值税的投资为基数进行计算,同时增值税不再进行抵扣项目收益的方法在不影响结果的同时大大简化了计算过程,在风电项目经济评价过程中推荐使用该方法。     

谈企业投资效益分析及管理

在市场经济条件下,每个企业做为参与平等竞争的独立的经营主体,受各种不确定因素的影响,各项经营活动无不与风险并存,特别是在投资方面,风险更大,而且往往是预期收益越高,风险越大,企业时常面临两难选择。而多种投资方案的选择又无不进行投入与产出的比较,最终都要落实到投资效益的分析及管理上,通过分析影响投资效益的各种因素,论证投资项目的可行性,慎重进行投资决策,以使企业获得最大的投资收益,提高企业投资的经济效果。

对投资组合理论分散化投资缺陷的探讨

投资组合就是将资金分散地投资于多个证券资产,以减少投资风险。1952年美国经济学家马柯维茨在《投资组合的选择》一文中提出均值-方差证券的现代投资组合理论。在证券市场上,对于机构投资者,面临着如何提高投资收益和降低投资风险的问题。从已有研究结果来看,在证券市场上当组合数量增加到一定程度后,组合收益的变动范围基本上保持不变甚至会转而下降。根据现代投资组合理论,投资组合只能降低非系统风险,而无法降低系统风险。从我国证券市场面临的风险来看,即使投资者持有一个与市场完全相同的投资组合,但是无法规避系统风险,持有一个完全的市场组合仍会面临比较大的投资风险。

Comparing FTTH access networks based on P2P and PMP fibre topologies

There is an ongoing discussion in the market which Next Generation Access (NGA) architecture best suits future needs and which investment and cost differences exist. The discussion can be subsumed as P2P vs. GPON, which is somewhat misleading as this article reveals. The discussion is driven by the fact that the high capital cost and the long asset life time of fibre mean that the technology choices made today will dominate the opportunities for telecommunication business of all market players, incumbents, competitors, content providers and business and residential users for many years in the future.The paper analyzes the cost and other differences between Fibre-to-the-Home (FTTH) access network architectures and their related different wholesale approaches by using the well-known and understood steady state approach applied in other NGA analyses in the past. In addition to the steady state analysis a dynamic cost evaluation is included taking into account the different investment behaviour of the FTTH architectures over time. The results describe investment and cost differences between architectures, incumbents and wholesale based competitive operators. The analysis has been performed for different geotypes (clusters) of decreasing population density in a representative European settlement structure.

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.     

Indigenous peoples’ nutrition transition in a right to food perspective

In indigenous communities the nutrition transition characterized by a rapid westernization of diet and lifestyle is associated with rising prevalence of chronic disease. Field work and literature reviews from two different policy environments, Argentina (Jujuy) and Canada (Nunavut), identified factors that add to indigenous peoples’ disease risk. The analytical framework was the emerging human right to adequate food approach to policies and programmes. Indigenous peoples’ chronic disease risk tends to increase as a result of government policies that infringe on indigenous peoples’ livelihoods and territories, undermining their economic system, values and solidarity networks. Policies intended to increase food security, including food aid, may also fuel the nutrition transition. There is a need to explore further the connection between well-intended policies towards indigenous peoples and the development of chronic diseases, and to broaden the understanding of the role that different forms of discrimination play in the westernization of their lifestyles, values and food habits. Food policies that take due account of indigenous peoples’ human rights, including their right to enjoy their culture, may counteract the growth of chronic disease in these communities.     

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.
