Corporate integrity, external assurance and sustainability reporting quality: evidence from the Malaysian public listed companies

PurposeThis paper aims to examine the effect of corporate integrity and external assurance on Sustainability Reporting Quality (SRQ) of Malaysian public listed companies.Design/methodology/approachThe study uses a longitudinal sample of 2,463 firm-year observations of non-financial firms listed on the main board of Bursa Malaysia from 2015 to 2019. The study employed panel regression that is, Fixed Effect (FE) Robust Standard Error estimation technique to test its hypotheses.FindingsThe panel regression results reveal that corporate integrity and external assurance positively and significantly influence the quality of sustainability reporting. Though the positive association shows an improvement in the SRQ of the sampled firms, it needs an improvement as the disclosure is more general and qualitative than quantitative. The present improvement in SRQ might result from some regulatory changes like the Sustainability Practice Note 9 Updates of Bursa Malaysia 2017 and the Revised MCCG Principle A to C within the same period.Research limitations/implicationsThe study adopts a purely quantitative approach and call for a qualitative investigation in the area in the future.Practical implicationsThe study has policy implication for the government and regulators to strengthen compliance with the sustainability reporting guide and the Practice Note 9 Updates. It also has implication for corporate integrity and external assurance for companies, to enhance SRQ and achieve sustainable development.Originality/valueThe study bridged literature gaps by offering new insights and empirical evidence on the role of corporate integrity in SRQ, which has received no empirical attention in the Malaysian context.
