Abstract: As the important mechanism of internal governance, the exit threat of non-controlling large shareholders will have a significant impact on the comparability of accounting information. Based on the sample of A-share listed companies from 2007 to 2020, this paper empirically tests the impact of the exit threat of non-controlling large shareholders on the comparability of accounting information. It is found that the threat of exit of non-controlling large shareholders has significantly improved the comparability of accounting information of listed companies. The exit threat of non-controlling large shareholders has a more significant impact on the comparability of accounting information in enterprises that are non-state-owned, have a high credibility of the exit threat, have no appointed directors, supervisors or senior managers, have less attention from analysts and face high environmental uncertainty. The mechanism test shows that the exit threat of non-controlling large shareholders mainly improves the comparability of accounting information by suppressing the agency problem of the management. The economic consequence test finds that the exit threat of non-controlling large shareholders promotes the comparability of accounting information and increases the enterprise value.
The research results of the paper confirm the governance role of the non-controlling large shareholders' exit threat, and provide new enlightenment for the expansion of corporate information governance channels. Enterprises should pay more attention to and give full play to the corporate governance role of non-controlling large shareholders, further promote the reform of the equity structure, highlight the equity balance and its governance effect, protect the reasonable right to know and the participation of non-controlling large shareholders, and create a better internal environment for strengthening corporate governance. At the same time, internal and external coordination is needed to further improve the external resource allocation, government supervision and other market environment while optimizing the internal equity structure and the governance environment, so as to effectively protect the interests of investors and promote the high-quality development of the market.
