摘　　要：本文将2020年我国提出“双碳”目标作为外生事件,构建双重差分模型研究高碳排放企业在“双碳”目标提出后审计费用的变化。研究发现,相较于低碳排放企业,高碳排放企业的审计费用在“双碳”目标提出后显著提高,即审计师在进行审计定价决策时充分考虑了企业面临的碳风险,并收取相应的“溢价”。进一步研究表明,企业碳风险的增加提高了企业经营风险,进而被收取更多的审计费用。此外,“双碳”目标提出后,审计师不仅充分考虑到了高碳排放企业面临的碳风险,也实质性加强了审计投入。同时发现,企业碳排放信息和环境信息的披露负向调节了碳风险与审计费用之间的正向关系。本文研究结论既丰富了碳风险与审计定价的相关研究,又为助力“双碳”目标的实现提供理论依据与政策参考。This study uses China’s dual carbon goals introduced in 2020 as an exogenous shock and employs a difference-in differences method to examine changes in audit fees for high-carbon emission firms.We find that audit fees for high-emission firms increase significantly following the introduction of dual carbon goals,compared to those for low-emission firms.This indicates that auditors takes carbon risks into account when determining audit fees and charge a“premium”to account for such risks.Further analyses show that heightened carbon risks increase the operating risks,which in turn results in higher audit fees.In addition,auditors not only consider carbon risks faced by high-emission firms following the introduction of dual carbon goals,but also increase audit inputs substantially.We also find that the disclosure of carbon and environmental information negatively moderates the positive relationship between carbon risks and audit fees.Our findings contribute to the literature on carbon risk and audit pricing,while offering theoretical and policy implications for achieving dual carbon goals.
