【摘要】：新世纪以来,随着网络信息技术的潮流不断向前推进,社会的信息化程度也越来越高,能够高效快速地使用信息成为企业的核心竞争力之一。然而想从现如今信息爆炸的环境中准确、快捷地找出企业所需要的财务信息再有效地加以利用并不是那么容易。正是在这样的背景之下,XBRL(Extensible Business Reporting Language,可扩展商业报告语言)应运而生,其出现引领了会计信息披露方式的革命,弥补了传统财务报告方式的局限性。XBRL依靠其无可比拟的优势在其诞生的短短十几年受到了各国会计界的重视和推崇,并得到了迅猛的发展。我国于2006年启动了XBRL项目,并于2009年要求所有的上市公司应用XBRL财务报告进行信息披露。经过了十年的不懈努力和探索,我国的XBRL在理论和实践方面都有了一定的规模。然而,高速的发展同时也带来了一系列的问题,比如在理论方面,XBRL的相关实证研究不足,在实践方面,一些上市公司出于应付,XBRL应用流于表面。本文正是看到了这些问题,想要通过站在市场反应的角度上对上市公司应用XBRL财务报告进行信息披露所产生的应用效果进行研究,希望以此为解决上述问题贡献绵薄之力,同时大致了解当前环境下我国XBRL的应用状况,总结经验,为更好地应用推广XBRL提供建议。本文主要采用事件研究法对应用XBRL所产生的应用效果进行研究,以2009年上市公司全面应用XBRL财务报告作为研究事件,以上市公司对外披露财务报告的披露日作为事件日,并确定相应的事件窗口期和事件估计期对本文提出的三个假设进行研究。应用SPSS软件进行了描述性统计分析、均值比较分析等实证分析方法之后,得出了本文的研究结论,即上市公司在对外披露财务信息时会在股票市场上产生反应,股票成交量会有有所增加,而当上市公司在应用XBRL财务报告进行信息披露之后,在股票市场上所产生的反应也会进一步加深,股票成交量相比于应用之前会有更为显著的增加,且市场反应的滞后性相比应用之前也有明显的削弱。希望以这些结论证明上市公司是值得在XBRL上投入资源的,以此推动XBRL在我国的再推广。
[Abstract]:Since the new century, as the trend of network information technology continues to advance, the degree of information technology is becoming more and more high, and the ability to use information efficiently and quickly becomes one of the core competitiveness of enterprises. However, it is necessary to find out the financial information needed by the enterprise effectively and effectively to make use of the financial information in the environment of the information explosion now. It is not so easy. It is in this context that XBRL (Extensible Business Reporting Language, extensible commercial Reporting Language) came into being, and its emergence leads to the revolution of accounting information disclosure, which makes up for the limitation of the traditional financial reporting mode,.XBRL with its unparalleled advantage in its birth. In 2006, the XBRL project was started in China, and in 2009, all listed companies were asked to use the XBRL financial report for information disclosure. After ten years of unremitting efforts and exploration, China's XBRL has a certain scale in both theory and practice. At the same time, the development of high speed also brings a series of problems, for example, in theory, the empirical research of XBRL is insufficient. In practice, some listed companies are on the surface of XBRL application out of dealing with them. This article is to see these problems and want to apply the XBRL financial report to the listed companies from the point of view of the market reaction. In order to solve the above problems, we hope to make a great contribution to solve the above problems. At the same time, we can roughly understand the application situation of XBRL in our country under the current environment, summarize the experience, and provide some suggestions for the better application of XBRL. This paper mainly uses event research method to study the application effect of the application of XBRL, 20 In the past 09 years, the listed companies used the XBRL financial report as the research event. The disclosure date of the listed companies' disclosure of financial reports was taken as an event day, and the corresponding event window period and the event estimation period were determined to study the three hypotheses. The descriptive statistical analysis was carried out with the SPSS software, and the mean comparison analysis was used. After the analysis, the paper draws the conclusion that the listed companies will react in the stock market when disclosing financial information, and the stock turnover will increase, and when the listed companies use the XBRL financial report to disclose the information, the reaction in the stock market will be further deepened. There will be a more significant increase in the volume of traffic than before the application, and the lag of the market reaction has been significantly weakened before the application. It is hoped that these conclusions can prove that the listed companies are worth investing in the XBRL in order to promote the re promotion of XBRL in our country.
