Study On Reliability Evaluation Model Of Accounting Information And Its Application For Chinese Listed Companies

In the stock market, accounting information is an important basis for investment decisions, according to statistics, 150 million, nearly half the number of investors use accounting information of listed companies for stock trading, but the reliability of face recognition difficulties and accounting information lack of independence of the audit opinion, the dilemma of the government regulatory delays, lack of effective protection of the interests of investors. The accounting profession at home and abroad reliability of accounting information a lot of qualitative research, and achieved rich results. But from the perspective of investor protection, quantitative measurement of the reliability of accounting information research is still very weak, yet to establish a scientific measure index system and model. Therefore, from an investor point of view, building an index of accounting information system and model of reliability measures, has a strong practical and theoretical significance.This paper attempts to balance sheet, income statement and cash flow statement articulation between projects, to select indicators measure the reliability of accounting information. Based on this idea, the paper design of the 25 first evaluation, and strive to fully reflect the reliability of accounting information. Secondly, this collection from 2007 to 2009 listed companies in the sample and the authenticity of the information distortion in the total sample of 500, on the evaluation index system of empirical test and optimization, are the current assets / current liabilities, total accruals / operating income, net profit / total assets, operating income / gross profit, net profit / operating income, income / gross profit indicator system consisting of six indicators. Construction of accounting information for the reliability evaluation, we use principal component analysis to give weight to the index constructed by the linear weighted evaluation model. And in 2007-2009 a sample of 954 companies, an empirical test of the model, test results show that model to evaluate the accuracy rate was 79%, the model accuracy is slightly higher compared to similar research at home and abroad. Finally, the application of the model, select a total of 13 companies in the agricultural sector to apply the sort. Sort results show that the model with reliability measures the value of the value of profit manipulation means of monitoring and early warning value.
