摘　　要：随着企业盈余宣告的多元性,非一般公认会计准则的收益信息(非准则收益信息)披露对社会产生的影响一直是学术界和实务界探讨的问题。了解非准则收益信息是否具有企业经营的真实含义,能够协助投资人对企业运营前景有更进一步的认知。基于此,文章以医疗行业的股价风险为对象,同时采用会计盈余与非准则收益信息进行影响分析。实证结果表明,会计盈余变动与非准则收益信息变动对股价风险产生了影响,其中会计盈余变动与股价风险呈现显著负相关关系,企业盈余越高,股价风险越低;非准则收益信息变动与股价风险呈显著正相关关系。With the diversification of corporate earnings declaration,the impact of non-GAAP income information(non-standard income information)disclosure on society has always been discussed by the academic and practical circles.Understanding whether the non-standard income information has the true meaning of enterprise operation can help investors to have a further understanding of the prospect of enterprise operation.Based on this,this paper takes the stock price risk of the medical industry as the object,and uses accounting earnings and non-standard income information for analysis.The empirical results show that the changes of accounting earnings and non-standard earnings information have an impact on stock price risk,in which there is a significant negative correlation between accounting earnings changes and stock price risk,that is,the higher the enterprise earnings,the lower the stock price risk,and there is a significant positive correlation between the change of non-standard earnings information and stock price risk.
