投资者情绪与股票收益——来自移动互联网的实证研究

移动互联网的高速发展使得越来越多的投资者通过移动互联网获取信息并做出投资决策。文章利用网络爬虫技术收集来自移动互联网的用户讨论信息，研究来自移动互联网的用户情绪对股票收益的影响，实证结果显示：移动互联网用户情绪存在显著不对称特征，其更倾向于表现积极乐观的情绪，且其正负面情绪差异大于PCs端；同时，移动互联网用户情绪越乐观，下一期股票收益越高。进一步实证结果表明，处于较差信息环境（如散户持股较高，分析师跟踪人数较少）的公司，移动互联网用户情绪对其股票收益的影响更加显著；此外，对于流动性越差的公司，移动互联网用户情绪对其股票收益的影响也越显著。文章研究结论为移动互联网时代的投资者优化投资决策提供了新的视角，也是对行为金融学中传统媒体定价领域的重要补充。

Commercial B2B Web Site Attributes Within the Perishable Sector

ABSTRACT

This study examines the factors determining the quality of a business-to-business web site using data from the perishable industry. Data from two time periods are used to identify the persistent trends in web features that support customer interaction. A binomial probit model is used to assess the contribution that various features have on the probability of a web site being included in the Forbes listing of prominent web sites. The results indicate that features such as customer support, promotion, proprietary software availability, and the duration of web site operation play an important role in determining the probability of a website being listed in the Forbes list.     

International Web Development

Abstract

Throughout the world, use of the Internet is growing exponentially and bringing mankind closer together. The Internet has become a powerful force in people's lives bringing information from around the globe to the tip of one's fingertips, changing the way the world purchases products and services, and creating new means of communication and media. The possibilities created by the Internet would seem limitless. Unique to each region of the world though is the degree to which the Internet has been adopted and is being utilized. The progression of Internet development has been shown to occur in three stages: acquisition of Web literacy, Web use as an information medium, and Web use for purchasing goods and services. In each of the following geographical regions, North America, South America, Africa, Europe, Middle East, Asia and Oceania, countries can be described as existing in one of these stages. A sampling of the countries within each region analyzes how and to what degree the people of that nation utilize the Internet and who provides the services offered, what services are offered, and obstacles presented in offering those services. Furthermore, the role the Internet plays in commerce, and the extent to which the government of that country has taken in regards to its polices in either regulating and/or promoting the Internet is examined. The factors have been shown to be important in Web development. Today the United States is at the forefront of Internet use and technology; however, it will not be long before that position is challenged by Japan and other countries in Europe and Asia as the Internet becomes more pervasive across the globe.
