在客户资源越来越受重视的今天,客户关系管理(CRM)作为一种"以客户为中心"的营销理念,正被越来越多的企业所采用。而随着客户数据的不断扩充和膨胀,要求有一种更为有效的工具对这些数据进行采集和管理,这一有效手段就是数据仓库技术。文章论述了数据仓库的内涵及其对CRM的重要意义,并对如何运用数据仓库技术为CRM服务提出了一些看法和见解。 相似文献

We consider the estimation of autocovariances using panel data with incidental trends under double asymptotics. The conventional autocovariance estimator suffers from a bias whose value is approximated by twice the long-run variance. We propose a bias-corrected estimator. 相似文献

This is an empirical study on the growth impact of Information and Communication Technologies using industry-level data for the US and the EU industries over the period 1980-2000. A panel data approach is employed to estimate the ICT effect using the system GMM and the pooled mean group panel data estimators. The results vary depending on the period, the region, and the type of industry considered. The GMM estimates suggest a significant ICT effect on growth during the 90s both in the US and in the EU. This effect for the EU was strong in the early 90s and weakened afterwards, as opposed to the US where it strengthened in the late 90s. The results of the pooled mean group estimator confirm that the long run growth contribution of ICT was significantly positive in the industries of both regions and over the entire period 1980-2000. However, it seems that the productivity effects of ICT are mainly present in the industries which are either ICT producers or heavy ICT users. 相似文献

在基于利益相关者理论建立衡量房地产业履行社会责任的指标体系和用托宾Q值衡量企业价值的基础上,分别对2000—2009年房地产业履行社会责任和企业价值进行评估,并利用面板数据模型对中国2000—2009年房地产业履行社会责任和企业价值的关系进行实证研究。研究表明:企业社会责任履行情况越好,越被社会公众认同,企业价值就会越高。但是社会责任的综合表现对企业价值的提升作用十分微弱,整个社会对企业社会责任的履行情况关注程度还十分有限。 相似文献

基于2000-2009年我国西部地区省际面板数据,使用TSLS工具变量法,运用面板数据单位根检验,协整检验和误差修正模型,对西部大开发战略实施十年以来西部地区金融发展与经济增长的长期关系和短期关系进行了实证研究。实证结果表明,西部各省份经济增长的金融贡献度存在差距;西部地区金融发展、控制变量与区域经济增长具有长期稳定的均衡关系,而金融支持的短期效应并不明显。为此,在推进新一轮西部大开发的过程中,须进一步深化金融体制改革,加快转变经济增长方式,提高区域经济增长质量。 相似文献

This study contributes to research on the impact that consumer buzz has on movie distribution and box office success by examining the impact of buzz generated about the individual stars and about the movie itself. The results indicate that movie buzz is instrumental in boosting box office revenue throughout the theatrical release, not just in the later run, as has been suggested in previous studies. Star buzz can enhance box office receipts during the opening week and can contribute to the public's anticipation of the movie pre-release. However, early buzz can have a negative impact on revenue during subsequent weeks if the movie fails to resonate with the audiences. Model simulations reveal that, even for poorly received films, the overall impact of star buzz is positive because the initial revenue boost normally outweighs the later decline. Thus, this study empirically demonstrates the positive impact of star buzz on revenue, which helps shed light on the long-standing debate regarding the importance of star participation in the success of a movie. 相似文献

Air cargo demand is an important aspect of the operation and planning of private and public agencies responsible for airports. While most existing studies in this field include only geo-economic characteristics of airports and their hinterlands as explanatory variables, this study develops a gravity model of air cargo flows by trying to incorporate more factors that might influence international air cargo flows of an airport. The model is developed based on the panel data of air cargo services on scheduled routes at Taiwan Taoyuan International Airport during the years 2004-2007. The results indicate that population, air freight rate and three dummy variables, including the regional economic bloc of the “Chinese Circle”(an informal partnership between Hong Kong, Macao, Taiwan and mainland China), the Open Sky Agreements and long established colonial links, are key determinants of international air cargo flows from/to Taiwan. These results suggest a wider array of factors needs to be considered in policy. 相似文献
