企业技术创新风险的聚类分析:一项实证研究

技术创新已经成为许多企业在市场竞争中获得竞争优势的重要途径,但是各种风险因素的存在使得企业技术创新的成功率并不高。以问卷调查为基础,以有向聚类为工具,通过实证分析对各种技术创新风险因素进行了聚类,归纳出了相对重要的风险因素。对这些因素的提炼,有助于企业理解并缓解技术创新的风险。     

R＆D项目影响因素的筛选及优化分析

影响R&D项目成败的因素是多种多样的,来自于方方面面。在实证调研的基础上建立了影响因素初选集,之后针对不同类型的因素,分别运用字2检验、T检验及因子分析的方法对初始因素集进行优化,为项目的评价工作建立更为科学、有效的指标体系。     

农业自然资源与食物生产的类型迭置分析—以福建省为例

福建省粮食缺口逐年拉大,其它副食品也出现程度不同的短缺信号。在食物短缺的背后隐含着农业自然资源数量的短缺,并且随着人口的增长而日益严重。本文从农业自然资源与食物生产的内在联系入手,尝试对其丰乏程度进行定量的地域划分和迭置分析,进而探索各地域类型的食物发展方向与总体对策。     

上市公司审计收费影响因素的实证研究

本文利用我国深沪两市A股上市公司2003年年报中披露的数据,对可能影响我国上市公司年度审计费用的主要因素,运用多元线性回归进行实证分析。研究结果发现,上市公司资产总额、纳入合并报表的控股子公司数目、其他应收款占总资产的比例、公司和事务所是否位于经济发达地区和董事会规模与年度审计费用显著正相关,而独立董事人数与年度审计费用显著负相关;应收账款占总资产的比例、存货占总资产的比例、审计意见、当年和前一年度的盈利状况等因素对年度审计费用的影响并不显著。因此,我国上市公司审计费用主要由审计的产品费用所决定,从而会计师事务所的审计收费主要反映了现实的审计成本,而审计风险等潜在风险成本并没有在审计收费中体现出来。     

Revealed preference and differentiable demand

Summary. We prove that, for finitely many demand observations, the Strong Axiom of Revealed Preference tests not only the existence of a strictly concave, strictly monotone and continuous utility generator, but also one that generates an infinitely differentiable demand function. Our results extend those of previous related results (Matzkin and Richter, 1991; Chiappori and Rochet, 1987), yielding differentiable demand functions but without requiring differentiable utility functions.Received: 1 November 2001, Revised: 5 February 2004, JEL Classification Numbers: D11, D12. Correspondence to: Kam-Chau WongThis is a much revised version of Lee and Wong (2001). We are grateful to the Referee for valuable suggestions. We also thank Professor Marcel K. Richter for his comments.     

Declining Discount Rates: The Long and the Short of it

The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances are to be applauded, the practitioner is left with a confusing array of rationales and the sense that almost any discount rate can be justified. This paper draws together these different strands and provides a critical review of past and present contributions to this literature. In addition to this we highlight some of the problems with employing DDRs in the decision-making process, the most pressing of which may be time inconsistency. We clarify their practical implications, and potential pitfalls, of the more credible rationales and argue that some approaches popular in environmental economics literature are ill-conceived. Finally, we illustrate the impact of different approaches by examining global warming and nuclear power investment. This includes an application and extension of Newell and Pizer [‘Discounting the benefits of climate change mitigation : how much do uncertain rates increase valuations?’ Journal of Environmental Economics and Management 46 (2003) 52] to UK interest rate data.

我国城市商业银行的经营模式选择分析

自城市商业银行成立之初，其经营活动就被限制在所在城市。但是近几年来，单一城市制经营模式的负面效应日益显现，并成为城市商业银行进一步发展的障碍。随着地区经济一体化和金融一体化的发展，资金的跨地区流动日益频繁，客户对银行服务和产品的要求也日益多元化，尤其是需要商业银行能够跨区域为其提供金融服务。伴随着城市商业银行改革的向前推进，城市商业银行要求联合、跨区域发展的愿望越来越强烈。实行新的经营模式才能提高城市商业银行的整体发展水平和市场竞争能力。     

Evaluating flood risk management options in Scotland: A participant-led multi-criteria approach

The characteristics of flood risk management include complexity, large spatial scales, inter-temporal issues, plural values and conflicts of interests. It is argued that issues with such characteristics require public participation in the decision making process. This study builds on existing deliberative processes to develop a new participant-led multi-criteria method to evaluate flood risk management options in Scotland. The results show that participants preferred regeneration or planting of native woodland to other flood management options, and least preferred building flood walls and embankments. The design of the workshops allowed a rich dataset to reveal the thinking behind such results and provided a deeper understanding of why participants came to these conclusions.
