| In recent years,financial fraud cases continue to occur,and the quality of accounting information of listed companies has always been the focus of attention.Accounting information is the medium for outsiders to know about the company’s operating conditions,and financial report is one of the channels favored by outsiders to know accounting information.The auditor is the gatekeeper of the last procedure before the financial report is disclosed to the public.If the auditor fails to handle the last step and the quality of the audit service provided is lacking,the quality of the financial report will be affected,and the accounting information will be distorted,thus affecting the major decisions of external personnel and even the healthy and orderly development of the whole market.Therefore,the auditor plays an irreplaceable role in the quality of accounting information.As a tradable commodity,audit service also conforms to the "supply and demand" theory in essence,that is,the quality of audit service depends on both the auditor who provides audit service and the client company that accepts audit service.Therefore,this paper takes both supply and demand sides of audit service market as the breakthrough point to study the impact of mismatches between customers and auditors on the quality of accounting information.Through a series of theoretical analysis and empirical tests,this paper draws the following two conclusions:(1)The mismatch between customers and auditors has significant impact on the quality of accounting information,among which the upward mismatch improves the quality of accounting information,while the downward mismatch weakens the quality of accounting information.(2)Regional social trust and management ability can play a moderating role in the impact of mismatch between customers and auditors on the quality of accounting information.In the regions with low social trust or weak managerial ability,the downward mismatch between customers and auditors weakens the impact on the quality of corporate accounting information.In regions with high degree of social trust or managers’ ability,the upward mismatch between customers and auditors has an increased impact on the quality of corporate accounting information.Compared with the existing literature,the contribution of this paper mainly includes three aspects: First,it confirms the influence of the mismatch between clients and auditors on the quality of accounting information,and enriches the influencing factors of the quality of accounting information;Second,it is not limited to the single company or audit perspective that the existing research affects the quality of accounting information,but from the audit service market,combining the supply and demand sides of audit services to analyze the impact on the quality of accounting information,enriching the economic consequences of the mismatch between customers and auditors;Third,it provides a reference angle for external accounting information users to judge the quality of accounting information and make a series of related business decisions. |
