The opinion proposes to strengthen the responsibility of intermediary institutions as gatekeepers. Promote the intermediary institutions' practice evaluation mechanism with the quality of listed companies and bond issuers as the guiding principle. Supervise intermediary institutions such as sponsoring institutions, accounting firms, asset appraisal institutions, and law firms to strengthen quality control. Strengthen the supervision and inspection of intermediary institutions. If an intermediary institution finds any fraudulent behavior by securities issuers or listed companies, it must promptly report to the financial and securities regulatory authorities. If an intermediary institution takes the initiative to report fraudulent behavior, it will be punished lightly or mitigated in accordance with the law. Establish the credit record of intermediary institutions and their practitioners, and supervise relevant agencies and personnel to be diligent and responsible. For intermediary institutions with significant illegal or irregular acts, they will be suspended or prohibited from engaging in securities business in accordance with the law, and the revocation of practice licenses and prohibition of personnel entry into the industry will be strictly enforced.
