The effect of mandatory XBRL and IFRS adoption on audit fees: Evidence from the Shanghai Stock Exchange

Abstract

Purpose

The purpose of this paper is to evaluate the impact of the International Financial Reporting Standards (IFRS) and eXtensible Business Reporting Language (XBRL) on audit fees based on evidence from listed companies operating in an emerging economy. Whilst IFRS constitute high-quality accounting standards, XBRL represents a technology standard that can enhance the usability of IFRS and overall financial reporting transparency.

Design/methodology/approach

Multivariate analyses are used on a sample of 1,798 firm-year observations between 2000 and 2011 from companies listed in the Shanghai Stock Exchange that were subject to XBRL and IFRS adoption mandates.

Findings

The main results suggest that XBRL has a main negative effect on audit fees which is weaker for larger firms. Additionally, the authors find that IFRS increases audit fees for all companies. Whilst this effect is positive for firms of different sizes, it is weaker for larger firms.

Research limitations/implications

Whilst the findings are applicable to the selected sample and may or may not be generaliseable to other economies, they can provide important implications for both regulators and companies that are undertaking IFRS convergence and XBRL implementation projects in developing economies around the world.

Originality/value

This study offers a timely assessment of the economic consequences of IFRS and XBRL on listed companies operating in an emerging economy, in addition to providing an important basis upon which further research can be designed in order to extend the analysis.
