中文摘要：

文章研究了费用粘性对上市公司盈余信息质量的影响,并进一步研究了费用粘性在不同情形下对盈余信息质量影响的差异。文章发现,费用粘性越大,公司会计盈余持续性越低,盈余反应系数也越小。研究结果同时表明,当公司管理层预期较为乐观以及在2008年金融危机之前,费用粘性对盈余反应系数的负向影响更大。最后,文章也发现有效的外部监督机制会抑制费用粘性的作用,国际四大审计公司的费用粘性与盈余信息质量的负向关联相对较弱。文章的结论对拓展费用粘性经济后果研究具有一定的理论价值。

英文摘要：

The paper investigate the impact of cost stickiness behavior on earnings information quality,and we further argue that the relationship between cost stickiness and earnings information quality depends on different settings. The findings indicate that more sticky cost induces lower earnings persistence and lower earnings response coefficients. We further find that managers＇ opportunistic expectation,firms＇ adjusted costs and agency costs moderate the relationship between cost stickiness and ERC. Overall,our findings can contribute to the research of economical consequence in related literatures.
