Quality evaluation of enterprise environmental accounting information disclosure based on projection pursuit model

摘要

To strengthen China's supervision of the quality of environmental accounting information disclosure and improve this quality, this paper established a set of evaluation systems. Based on the principles of "relevance" and "reliability", 28 evaluation indicators were selected, and a projection pursuit model was innovatively introduced according to the characteristics of the evaluation data in this study. This model can not only overcome the artificially weighted interference and restrictions on the data structure of the traditional evaluation method but also can achieve better robustness, anti-interference ability and accuracy when processing high-dimensional nonlinear data. To test whether the method is simple and effective, the study selected 34 thermal power listed companies in China as a sample. The evaluation results of the key quantitative indicators showed that the disclosure level of the whole sample is low, which indicates that the information disclosed by each enterprise is not substantial. After verification, the results are basically consistent with the original data. Finally, this paper analyzed the problems in the disclosure of the evaluation results and proposed feasible suggestions. (c) 2020 Elsevier Ltd. All rights reserved.
