Research On Extension Of XBRL Classification Standard

With XBRL technology is used and promoted, classification criteria as its most important component, the research of accounting standards for XBRL is particularly important. In October 2010, the ministry of finance issued 《The accounting standards for enterprises general classification standard》, prepared to improve financial reporting and use. However, general classification standards whether can meet the requirements of enterprise voluntary disclosure of information? Is it necessary to extend general classification standards? Enterprise classification standard extension will be influenced by what factors? This paper is based on the theory of classification standard and extension methods, adopts the method of combining empirical study and normative research, evaluates general classification standards of efficiency, studies the influential factors of the general classification standard extension, and advances some suggestions on the expansion of the general classification criteria. This paper provides the basis for the expansion of the XBRL general classification standard, provides a theoretical basis for the research of relevant theories. The main conclusions of this paper are as follows:(1) The usage of general classification standard in the enterprise financial disclosure is low, general classification efficiency remains to be improved, general classification standard is needed to extent. This paper compares companies to disclose financial information element with general classification standard element, the results shows that all samples enterprise general classification standard element reuse the mean rate of just 40.13%, general classification standard has larger expansion space.(2) In 2011, our country issued extension classification standards of oil and gas industry, based on the classification criteria of the extension element this paper lists of general classification standard element list to get new elements table, from three aspects from the completeness, accuracy and comparability this paper shows that classification standard extension will improve the quality of enterprise. Classification standard needs to be extended.(3) The empirical study, this paper assumes the eight elements which influence greatly the total extension elements, uses multiple linear regression. Test results show that the factors affecting enterprise classification standard extension, whether the degree of monopoly industries, management holding, equity concentration, total assets, return on equity, and revenue growth for extension elements have a significant impact on total classification standards.(4) To promote the extension and application of the classification criteria of XBRL in our country, following measures should be taken:developing high quality standard of general classification, enhancing the completeness and accuracy of the classification criteria of general, making and perfecting the extended standard of the industry, improving the quality of XBRL taxonomy standard, improving the level of XBRL supply chain personnel, raising the level of general education classification standard.
