Dynamic Measurement Of Earnings Quality Of Listed Companies From Electronic Components Industry

Earnings quality is a indicators which can reflect the earnings of listed companies for both quantity and quality.Research about earnings quanlity focus on factors that can make influence on the earnings quanlity, the property features and the methods of earnings quanlity'measurement. Along with the gradual consummation of research content about earnings quanlity,people found than that we should do some different research for each industry,because every industry has some unique industry characteristics,which make them be exclusive from others. So the starting point we do research on earnings quanlity from is changing to doing specific research on each specific industy. Electronic components industry got a great development in the last ten years,however,it faced its disaster for improvement because of the financial crisis broken out in 2008,no longer after that, the Government introduced a series of policies to support and guide the development of the electronic components industry.So,this article choose the electronic components industry as the research object and try to do some research on the measurement of earnings quanlity,including with the changing trends of this industry from 2000 to 2009.Dynamic measurement of earnings quality should be able to fit well with the industry characteristics of electronic components industry . So, it analyzed and discussed the industry characteristics and current development situation of the industry first. On the basis of which it raised the attributes characteristics (cash protection, security, growth, profitability, innovation and sustainability) of the earnings quanlity of electronic components industry and the specific information each property contains. The quantitative of these properties all need the original financial or non-financial as a basis, In this paper, according to the specific characteristics of each attribute, select 12 financial indicators to quantify the these properties. It obtained the earnings quality composite score of listed companies from electronic components by factor analysis, and using the rate of total assets of the enterprise and total assets of all the industry as weights, then got the earnings quality composite score of electronic components industry from 2000 to 2009. In order to make the dynamic measurement results have more practical value, it use the point of fuzzy statistical, changed the traditional point prediction into range prediction, before that,it must taken by a series of methods to convert exact value into the fuzzy interval data. Then, using exponential smoothing to calculate and analyze the dynamic changes trends of earnings quality of electronic components industry over time, and forecast.the earnings quanlity in 2010 together.Finally, in order to ensure the reliability of prediction,it did a practice test between the the actual observation in 2010 and the predicted results, the results show that the difference between the forecast errors are both within the acceptable range, which proved that this research results is reliable and can be use to solve the practical problems.
