Location selection plays a crucial role in the retail and service industries. A comprehensive location selection model and appropriate analytical technique can improve the quality of location decisions, attracting more customers and substantially impacting market share and profitability. This study developed a data mining framework based on rough set theory (RST) to support location selection decisions. The proposed framework consists of four stages: (1) problem definition and data collection; (2) RST analysis; (3) rule validation; and (4) knowledge extraction and usage. An empirical study focused on a restaurant chain to demonstrate the validity of the proposed approach. Twenty location variables relevant to five location aspects were examined, and the results indicated that latent knowledge can be identified to support location selection decisions. 相似文献

在改革开放中发展的中国物流事业 总被引:2,自引:0,他引:2
本文指出,进入新世纪以来,中国物流事业进入了全面发展的新时代,宏观物流管理得到加强,现代物流业快速发展,企业物流水平显著提升,交通运输和物流基础设施建设不断加强,物流教育规模迅速扩大,人才培养质量显著提高。但与经济快速发展、经济全球化及又好又快发展的要求相比,还存在很大差距。按照科学发展观的要求,处理好物流事业发展中的各种关系,包括处理好物流发展与环境保护和资源节约的关系,走绿色物流之路,是今后中国物流事业发展道路上,无论国家宏观层面还是企业微观层面,都要认真对待并努力解决的问题。 相似文献

This study investigated effects of codes of ethics on perceptions of ethical behavior. Respondents from companies with codes of ethics (n = 465) rated role set members (top management, supervisors, peers, subordinates, self) as more ethical and felt more encouraged and supported for ethical behavior than respondents from companies without codes (n = 301). Key aspects of the organizational climate, such as supportiveness for ethical behavior, freedom to act ethically, and satisfaction with the outcome of ethical problems were impacted by the presence of an ethics code. The mere presence of a code of ethics appears to have a positive impact on perceptions of ethical behavior in organizations, even when respondents cannot recall specific content of the code. 相似文献

The effect of advertising on consumer welfare has been the subject of dispute among economists, arising largely from disagreement among scholars regarding the persuasive versus the informative role of advertising. This paper reports two experiments that explore the welfare implications of advertising effects. Experiment 1 shows that the same advertisements can either increase or decrease prices paid for selected brands, depending on the degree to which the choice situation requires brands to be recalled in order to be considered. However, an increase in prices paid caused by advertising does not necessarily imply detrimental effects on consumer welfare. Experiment 2 shows that, even under circumstances in which differentiating advertising leads consumers to select brands with higher average prices, it can provide useful information to consumers that allows them to make purchases that are more in line with their personal tastes than are the choices of consumers not exposed to the advertisements. 相似文献

This paper shows that abnormal stock price returns around the date of open market repurchase announcements are four times higher in Germany than in the USA (12 ver. 3%). We hypothesize that this observation can be explained by national differences in repurchase regulations. Our empirical evidence indicates that German managers primarily buy back shares to signal an undervaluation of their firm. We demonstrate that the stringent repurchase process prescribed by German law attributes a higher credibility to undervaluation signals than do the lax US regulations, and thereby corroborates our hypothesis.Financial support from the E-Finance Lab, Frankfurt am Main, and from Freitag & Co., Frankfurt am Main, is gratefully acknowledged. We would like to thank two anonymous referees for their helpful comments 相似文献

This paper examines the out-of-sample forecasting properties of six different economic uncertainty variables for the growth of the real M2 and real M4 Divisia money series for the U.S. using monthly data. The core contention is that information on economic uncertainty improves the forecasting accuracy. We estimate vector autoregressive models using the iterated rolling-window forecasting scheme, in combination with modern regularisation techniques from the field of machine learning. Applying the Hansen-Lunde-Nason model confidence set approach under two different loss functions reveals strong evidence that uncertainty variables that are related to financial markets, the state of the macroeconomy or economic policy provide additional informational content when forecasting monetary dynamics. The use of regularisation techniques improves the forecast accuracy substantially. 相似文献

我国经济增长一直居于高位,但已有几种伴生现象,主要是商品过剩、资金过剩和失业率上升,正蕴育着一些风险或危机。这三者都是由生产过剩所引起。生产过剩意味着消费相对于生产已严重滞后。因此,要根治生产过剩,化解经济风险,关键是大力促进消费增长,并以消费启动经济运行全过程。坚持以消费带动投资增长,这是消费启动所固有的内涵和基本要求。 相似文献

本文从理论上分析了股权结构与公司价值间的关系,并通过实证研究考察上市公司所有权结构及由此而产生的代理成本与其市场价值之间的关系。检验结果与理论分析相一致:(1)上市公司存在控股股东,会使公司市场价值折价。(2)上市公司存在股权制衡,能够有效的减少公司代理成本,提升公司价值。(3)不同性质的控股股东所产生的代理成本不同,国家股东的非人格化使得公司的代理成本高于非国有股东。本文得出结论:我国的上市公司普遍存在控股股东,由此产生的代理成本减低了企业的价值,国有股东的代理问题尤为严重,股权制衡的模式能够在一定程度上缓解代理问题。 相似文献
