Comprehensive Evaluation Of The Profitability In China’s Electric Power Companies

The purposes of comprehensive evaluation of the enterprise’s profitability is to achieve the enterprise’s strategic objectives in the next time. Select appropriate indicators, then use scientific and reasonable method, determine the potential profitability and profitability of the enterprise. Profitability is the primary symbol of enterprise survival,and is closely related with investors, creditors and other interests.Therefore, make an objective and accurate evaluation to profitability of enterprises, is essential. Power industry are closely related to national economic development, in recent years, become the focus of attention, it is to evaluate the profitability Of China’s electric power companies.This article based on the current status of the power industry’s credit assessment, established credit evaluation index system of power industry. For the features of a large number of indicators, proposed based on rough sets and support vector machine credit evaluation model. Using rough sets of the attribute reduction algorithm to realize evaluation index reduction, Using support vector machine (SVM) is constructed, the regression algorithm has better generalization ability and the suppressing noise regression model, with real data index selection, weight calculation and comprehensive assessment, determine the electric power enterprise credit evaluation of comprehensive value, obtains each electric power enterprises optimized credit evaluation order rankings. And with the single support vector machine (SVM) model compared to verify the selected the effectiveness of the method, the results of the study show that the model is feasible, and good effects. Finally, based on the current situation of the electric power enterprise credit evaluation actuality and existing problems, and put forward some proposals.
