In 2005, the Shenzhen Stock Exchange promulgated and implemented the "Measures for the Assessment of Information Disclosure by Listed Companies on the Shenzhen Stock Exchange" and began to rate the quality of information disclosure of listed companies. The Shanghai Stock Exchange began this process in 2016 Work.
In terms of scoring standards, the Shanghai Stock Exchange and the Shenzhen Stock Exchange are slightly different. The Shenzhen Stock Exchange from 2005 to 2010 respectively evaluated the timeliness, accuracy, completeness and legality of the daily information disclosure of listed companies. We conducted a multi-dimensional evaluation of the information disclosure work of listed companies over the past year, taking into account factors such as rewards and punishments received by listed companies, cooperation with securities regulatory agencies, investor relations management and other factors. , and finally formed: Excellent, good, passing, failing, a total of 4 types of evaluation results.
In 2011, the Shenzhen Stock Exchange revised the "Shenzhen Stock Exchange Listed Companies' Information Disclosure Assessment Measures" and adopted a points addition and subtraction model to add or deduct points based on a unified assessment benchmark score. points, and combined with the negative list indicators, determine the assessment rating of listed companies. The basic score for the information disclosure assessment of listed companies is 100 points. The assessment ratings are divided into four levels from high to low: A, B, C, and D. The number of companies rated A accounts for no more than 25% of the total number of companies assessed strong>.
AndSince 2016, the Shanghai Stock Exchange has graded the quality of information disclosure of listed companies from July 1 of each year to June 30 of the following year, using the method of benchmark score plus approved increase or decrease scores, the evaluation benchmark is 80 points. In accordance with the prescribed evaluation standards and the scoring standards stipulated in the attachment, various contents of the information disclosure work of listed companies are evaluated, and points are added or subtracted based on the benchmark score to obtain the final evaluation score of the listed company. The final evaluation scores of each listed company form the annual evaluation results according to the following standards: (1) Those with 90 points (inclusive) and above are A; (2) Those with 80 (inclusive) and 90 points are B; (3) 60 (inclusive) and above A score of 80 is C; (4) A score below 60 is D.
With regard to the proportion of each grade in the rating results, the Shanghai Stock Exchange issued the "Measures for the Evaluation of Information Disclosure of Listed Companies on the Shanghai Stock Exchange (2017 Revision)" in June 2017, and considered that the assessment model with rigid delineation of proportions cannot reflect the The actual situation of the branch.
The original "Evaluation Method" stipulates that the evaluation results are divided into four grades A, B, C, and D. Among them, the proportion distribution of the first three grades is divided into 3:5:2, and the proportion of grade D is combined with grade C. From a practical perspective, the level of a company's information disclosure mainly depends on its own efforts and performance in information disclosure. Dividing evaluation results according to established rigid proportions may result in the evaluation results of some companies not reflecting their actual situation. For example, in practice, there may be situations where the number of Class B companies exceeds or falls below 50%. However, according to the rigid proportion, this part of Class B companies can only be classified into Class C or Class A. In view of this, the rigid proportional restrictions in the "Evaluation Methods" need to be revised.
CnOpenData summarizes and organizes the above data to form information disclosure scoring data of A-share listed companies for scholars to conduct detailed research on the quality of information disclosure of listed companies.
