交通基础设施建设与审计质量

Transport Infrastructure Improvement and Audit Quality

本文以2005-2018年我国A股上市公司为研究对象,讨论了高铁开通对审计质量的影响。研究结果表明,高铁开通能够显著提高审计质量;区分可操纵性应计利润的方向,高铁开通能够抑制上市公司的正向盈余管理,对负向盈余管理则没有显著作用;相较于中心城市,高铁开通对审计质量的提升作用在非中心城市更为显著;相较于国际"四大"会计师事务所,高铁开通对审计质量的提升作用在非国际"四大"会计师事务所更为显著。此外,文章还发现高铁开通降低了审计延迟,为高铁开通促进审计效率提升提供了进一步佐证。本文扩展了交通基础设施经济后果的研究,也丰富了地理距离与审计质量关系的研究。

Using a sample of Chinese listed firms during the period of 2005-2018,this paper examines the influence of high-speed railway opening on audit quality.The findings show that the high-speed railway opening can significantly improve audit quality.Moreover,the high-speed railway opening can restrain the positive discretionary accrual of listed companies,but has no significant effect on negative discretionary accrual.Further analysis shows that the effect of high-speed railway opening on audit quality is more significant for companies in non-central cities and for non-Big Four auditing companies.In addition,the high-speed rail opening reduces audit delay,which provides further evidence for the promotion of audit efficiency.This paper extends the study on the economic impact of transport infrastructure,and enriches the literature on the relationship between geographical distance and audit quality.
