本文在分析国内外公允价值会计理论与实证研究文献的基础上,探讨了国际金融危机后我国学术界对公允价值会计研究的新机遇.本文首先提出:引入行为金融学中的“行为异化”概念,以此作为连接公允价值与金融危机等会计准则后果研究的逻辑纽带,从而实现将公允价值会计的经济后果研究从“黑箱”变为“白葙”.同时,本文也认为:结合中国企业和市场特有的转型经济特征来研究公允价值会计的经济后果,将是我国公允价值会计研究取得原创性研究成果的关键所在. 相似文献

以新会计准则实施后2007-2012年年报披露RD投入的3640家上市公司为样本,从RD资本化与费用化会计政策选择的视角,分别检验了RD资本化与费用化会计政策选择对企业财务价值和市场价值的影响。研究结果表明:RD会计政策选择对企业的财务价值和市场价值产生完全相反的作用,RD会计政策选择与财务价值负相关,与市场价值正相关。企业选择将RD投入资本化能够增加市场价值,但不会增加财务价值;相反,企业选择将RD投入费用化则能够增加财务价值,不会增加市场价值。由此推断,企业RD投入资本化与费用化的会计政策选择是对企业财务价值和市场价值权衡的结果。 相似文献

以2010-2014年年报披露RD相关信息的8427家上市公司为样本,从调节效应的视角,运用经典股票价格模型和拆分后的股票价格模型进行分层回归,实证检验政府补助对RD会计政策选择与企业市场价值之间关系的影响。结果显示,RD会计政策选择具有价值相关性,政府补助又正向调节RD会计政策选择与企业市场价值之间的关系,同时也正向调节资本化RD投入及费用化RD投入与企业市场价值之间的关系。结果说明,企业管理层将RD投入进行资本化会计处理增加了企业的市场价值,而政府补助又加强了RD资本化选择的这种价值相关性。 相似文献

会计政策在形式上表现为会计过程的一种技术规范,但其本质上是一项社会经济和政治利益的博弈规则和制度安排,不同的会计政策选择产生不同结果的企业会计信息,会对企业利害关系集团产生不同的利益分配结果;因此会计政策选择不仅具有广泛的经济后果,而且还是各相关利益集团为转移财富而进行的政治博弈和竞争。文章就此现象分析我国会计制度改革历程与各个利益关系之间的博弈过程以及新会计准则带来的变革,阐述了作者在会计政策改革中自身的理解和得到的启示。 相似文献

会计政策,是指企业在会计核算时所遵循的具体原则以及企业所采纳的具体会计处理方法。会计政策选择可以说贯穿了整个的会计核算过程,从会计确认、会计计量、会计记录到会计报告都离不开会计政策的选择。会计政策作为企业提供会计信息的重要依据和内在标准,会对会计信息质量产生根本的影响。企业选择不同的会计政策会引起会计信息质量的差异,从而影响信息使用者进行经济决策。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

The main premise of this article is that in information societies generally, and in virtual social contexts particularly, a distinctive style of interaction to facilitate the communication of difference, heterotopic communication , has emerged. It rests on two cultural foundations: an ideological belief in the positive, socially integrating power of communication, and a prevailing ethic of instrumental rationality, subjective individualism, and strategically practiced self-interest. The former is demonstrated by the use of simulation and spectacle as sources of information; exhibitionism/voyeurism as a communicative style; and the awareness of surveillance. The latter is seen in the competitive use of knowledge as a commodity; a surface globalism masking deep parochialism; lateral as well as vertical information inequity; and the use of public versus private as strategies for engagement rather than as spaces. Those who engage in heterotopic communication resort to their 'own devices' both in the sense of personal agendas, strategies, interests, and interpretations, and in the form of the telecommunication tools that help realize them. These personal and technological devices allow individuals with the right educational and technical resources to avoid exposure to disagreement, difference, or other information that does not serve their direct purposes or reflect their particular views of the world; yet they also help convey the appearance of openness, availability, and cooperation. This style of interaction is used strategically in combination with information and communication technologies to gain social or economic advantages, but it may encourage social separatism and parochialism, inhibit the negotiation of disputes, and emphasize competing interests. 相似文献
