| At present,the development of information technology is entering a new stage,and the era of ubiquitous computing,software-defined everything,and all-embracing network has come.In this new situation,the accounting information disclosure environment has changed significantly.Traditional reports in PDF,EXCEL and other formats can no longer meet the needs of information users for timeliness and low cost.XBRL,with its advantages in data standardization and structure,helps enterprises to disclose information on the standardized platform.It only needs to prepare a statement once to extract information according to different needs,and even analyze the data,so as to maximize the efficiency of information transmission and reduce the transmission cost.As an important product of XBRL application in accounting information disclosure,XBRL financial report has become an inevitable trend of information disclosure in the new period.However,the application of XBRL in Chinese enterprises is still in the preliminary stage,and there are still many problems to be solved in the application process.As the first batch of XBRL pilot units,Chinese Petroleum Corporation began to apply XBRL in 2011,launched the construction of "XBRL + big data" project in 2015,and basically applied and implemented the "XBRL + big data" technology in2017.Therefore,it is necessary and of practical significance to study it deeply.Under this background,this paper selects Chinese Petroleum Corporation,which is in the leading position in XBRL application,as the research object and focuses on XBRL financial report from the perspective of accounting information disclosure.Firstly,the application status of XBRL in Chinese Petroleum Corporation is expounded from the aspects of XBRL expansion classification standard,XBRL financial report preparation and reporting process,information disclosure,etc.Secondly,questionnaire survey and time study were used to analyze the application effect of Chinese Petroleum Corporation XBRL from both internal and external aspects.Finally,the application status and effectiveness of Chinese Petroleum Corporation XBRL are combined.It is found that there are problems in Chinese Petroleum Corporation’s application of XBRL in three aspects: classification standard,enterprise application and external support,such as imperfect classification standard,insufficient application of XBRL financial report and inaccurate information disclosure.In view of these problems,this paper puts forward some Suggestions.Firstly,at the level of classification standards,the classification standards can be improved from the perspectives of integrity and efficiency.Secondly,at the enterprise application level,we can optimize the internal information monitoring environment,make good connection between ERP and XBRL,and establish a financial early warning system based on XBRL financial report.Finally,in the aspect of external support,enterprises can be encouraged to accelerate the cultivation of XBRL compound talents and encourage the development of XBRL supporting software.I hope to provide experience for other enterprises to apply XBRL,and contribute to the development of XBRL. |
