市场风险是证券投资领域中备受关注的主题,一直是理论界和实务界的研究热点。本文以沪深两市A股上市公司作为研究样本,从应计质量视角来度量上市公司的会计信息质量水平,运用面板VAR模型实证检验了会计信息质量对市场风险的影响。研究结果表明,上市公司会计信息质量水平在短期内与其市场风险呈现显著负相关关系,经过长期的调整过程,这种冲击效应逐渐弱化,逐渐趋向于0;通过方差分解得出,会计信息质量是市场风险的重要影响因素。在实证检验的基础上,提出了完善会计信息披露制度的政策建议。
市場風險是證券投資領域中備受關註的主題,一直是理論界和實務界的研究熱點。本文以滬深兩市A股上市公司作為研究樣本,從應計質量視角來度量上市公司的會計信息質量水平,運用麵闆VAR模型實證檢驗瞭會計信息質量對市場風險的影響。研究結果錶明,上市公司會計信息質量水平在短期內與其市場風險呈現顯著負相關關繫,經過長期的調整過程,這種遲擊效應逐漸弱化,逐漸趨嚮于0;通過方差分解得齣,會計信息質量是市場風險的重要影響因素。在實證檢驗的基礎上,提齣瞭完善會計信息披露製度的政策建議。

Market risk is a topic highly concerned in the field of securities investment, which has been a research focus of the theoretical and practical circles. This paper chooses the Shanghai and Shenzhen A-share listed companies as samples, measures the accounting information quality of listed companies from the perspective of accruals quality, and empirically tests the effect of accounting information quality on market risk using the panel VAR model. The results show that the level of accounting information quality of listed companies and its market risk presents a significant negative relation in the short term. After a long process of adjustment, this shock effect gradually weakens, and gradually tends to zero. The variance decomposition draws that the accounting information quality is an important impact factor of market risk. At last, we propose policy recommendations to improve the accounting information disclosure system based on the empirical test.
